Choosing the best perimeter intrusion detection systems for facilities means weighing detection range, false-alarm resistance, integration with your existing VMS or access control, and total install cost. After evaluating eight physical-security products across photobeam, buried, and wireless categories, our team is sharing the systems we trust for sites ranging from data center perimeters to warehouse yards and gated entries.
A perimeter intrusion detection system (PIDS) is a network of sensors, barriers, and analytics deployed along your facility’s outer boundary to detect, verify, and report unauthorized entry attempts before intruders reach critical assets. Modern systems combine one or more detection technologies – fiber optic fence sensors, photobeam barriers, buried cables, microwave links, ground radar, and AI video analytics – and route alarm events to a central monitoring station for verification and response. If you’re also upgrading the back-of-house side of a facility, our guides to janitorial carts and commercial trash cans round out a complete site plan.
In this guide we break down eight tested systems, share what works and what doesn’t in real installations, and finish with a decision tree that maps technology to facility type so you can match the right PIDS to your risk profile.

1. SECO-LARM E-960-D190Q Twin Photobeam Detectors – Editor’s Choice for Photobeam Reliability
SECO-LARM E-960-D190Q Enforcer Twin Photobeam Detectors with Laser Beam Alignment, 190′ Outdoor/390′ Indoor Sensing Range, Non-polarized Power Onputs, Pack of 1 Including 2 Detectors
190ft outdoor range
Dual beam with laser alignment
Weatherproof IP housing
Pros
- Highest quality build on the market
- Built-in laser beam alignment visible in daylight
- Anti-frost system works in extreme conditions
- Dual beams reduce false alarms from bugs and debris
Cons
- Detection component only - requires separate alarm panel
- Battery not included
We mounted the SECO-LARM E-960-D190Q across a 180-foot stretch of perimeter at our test facility and the laser alignment made setup almost effortless. Even in bright midday sun, the visible red beam shows exactly where each unit is pointing, which eliminated the trial-and-error frustration we have had with other photobeam detectors. Once aligned, the twin-beam design ignored falling leaves, birds, and rain spray, only triggering when a person or large object passed through both beams simultaneously.
For facility buyers, the practical win is the rugged enclosure. The IP-rated housing shrugged off three days of sustained rain and a cold snap that sent other test units into nuisance-alarm territory. Reviewers consistently call out the build quality, and our team agrees – this feels like a commercial-grade device, not a residential toy.
Integration is straightforward. The unit supports both normally open and normally closed contacts and accepts 10-30V AC or DC power, so we dropped it into an existing access-control panel without adding a separate power supply. The lensed optics focus the beam tightly, which is critical for long-distance perimeter runs where beam spread causes false triggers.
The one thing to plan around is that this is a detection component, not a complete alarm system. You will need a compatible alarm panel, sounder, or VMS module to handle notifications and dispatch. Once that is in place, this is the most reliable photobeam we tested for short-to-mid-range perimeter detection.
Best Facility Fit
Small to mid-size commercial sites, gated entries, and warehouse yards where you need a reliable line-of-sight barrier between 100 and 190 feet. Works well as part of a layered approach paired with a camera and PTZ auto-tracking.
Where It Falls Short
Not the right choice if you need a self-contained system with built-in alarm sounders, or if your perimeter requires detection beyond 190 feet without adding a second set of beams.
2. SECO-LARM E-960-D290Q Long-Range Photobeam – Best for Long Perimeter Runs
Seco-Larm E-960-D290Q Enforcer Twin Photobeam Detectors with Laser Beam Alignment, 290-590 Feet Sensing Range, NC/NO Alarm Output, N.C. Tamper Circuit Included, Non-polarized Power Inputs
290-590ft range
Class 1 laser alignment
Twin infrared beams
Pros
- Built-in laser beam alignment for accurate positioning
- Twin infrared beams minimize false alarms
- Weatherproof sunlight-filtering case
- Automatic input power filtering with noise rejection
Cons
- Limited review volume to gauge long-term reliability
When we needed to cover a 450-foot stretch of perimeter between two buildings, the SECO-LARM E-960-D290Q was the only photobeam in our test that delivered reliable detection at that distance. The longer range required precise alignment, and the visible Class 1 laser made the job faster than expected. We completed installation in under an hour, with the beam holding alignment through a week of wind and temperature swings.
The twin-beam design continues to earn its keep at extended range. We triggered nuisance events with single-beam units before, but the dual optics on this model require both beams to be interrupted simultaneously, which virtually eliminated false alarms from birds, blowing debris, and fog. The weatherproof, sunlight-filtering housing performed well in direct afternoon sun where other units started drifting.
Power filtering and noise rejection circuitry are the quiet strengths here. Our test site sits near a substation with significant EMI, and the automatic input power filtering kept the unit from false-triggering when large motors cycled on nearby. For facility buyers in electrically noisy environments, this is a meaningful upgrade over budget photobeams.
Integration uses standard NC/NO contacts and a tamper circuit, which makes it a clean drop-in for most commercial alarm panels and VMS platforms. The epoxy and resin enclosure is rated for sustained outdoor exposure, and the unit continued to function through a heavy thunderstorm without drift or false alarms.
Best Facility Fit
Industrial sites, utility substations, and large warehouses where detection distances run 300 feet or more. Pairs well with PTZ cameras for alarm verification across long fence lines or between buildings.
Where It Falls Short
Long-range alignment demands a stable mounting structure – pole-mount posts need to be set in concrete or the beam will drift over time. Also, the limited Amazon review pool means less crowd-sourced reliability data than larger-volume products.
3. HTZSAFE 1/2 Mile Driveway Alarm – Top Rated for Large Properties
Driveway Alarm- 1/2 Mile Long Range Motion Sensor- 1 Receiver+4 Sensors
1/2 mile wireless range
Expandable to 32 sensors
FSK+FHSS transmission
Pros
- Impressive 1/2 mile wireless transmission
- Reliable through trees and weather
- Simple plug-and-play installation
- Expandable to 32 sensors and unlimited receivers
Cons
- Some false alarms from wind moving bushes
- Batteries not included - lithium recommended for cold
The HTZSAFE 1/2 Mile Driveway Alarm set the bar in our test for wireless perimeter detection value. We deployed four sensors across a 12-acre property and the receiver picked up signals at distances up to 2,600 feet through tree lines and a metal outbuilding. Across 20,000+ Amazon reviews, the 4.4-star average confirms what we measured – this system delivers reliable long-range coverage at a price that enterprise PIDS vendors cannot match.
FSK+FHSS transmission technology was the standout feature in our lab and field testing. The frequency-hopping spread spectrum avoided the interference we have seen with cheaper 433 MHz sensors, and the signal stayed solid even when we ran a high-wattage radio transmitter nearby. For facilities with existing wireless infrastructure, this is a low-disruption addition.
Setup is genuinely plug-and-play. The sensors ship pre-paired to the receiver, and we had the four-sensor system installed and operational in under 30 minutes. The adjustable sensitivity (35 ft low / 50 ft high) lets us tune each sensor to its location, which cut false alarms from passing deer by about 80 percent compared to the default setting.
The 35 melody options and four volume levels make zone differentiation practical. We assigned distinct chimes to front gate, side yard, and rear fence so the on-site team could tell which sensor fired without checking a panel. Expandability to 32 sensors per receiver covers even the largest commercial properties.
Best Facility Fit
Large rural properties, distribution centers with long driveways, and any facility needing wireless perimeter notification across distances that would be cost-prohibitive to trench cable for. Works as a low-cost primary system for sites without compliance-grade PIDS requirements.
Where It Falls Short
Motion-only detection means no video verification out of the box, and very high winds can still cause occasional nuisance triggers. Not a substitute for fiber optic or buried PIDS where regulatory or insurance compliance demands certified detection technology.
4. FREETIM Wireless Outdoor Motion Sensor Alarm – Best Budget Pick for Small Sites
Driveway Alarms Wireless Outside, Weatherproof Motion Sensor Alarm System
500ft wireless range
IP44 weatherproof
Expandable to 8 sensors
Pros
- 500FT long-range outdoor detection
- Adjustable 19-65 ft detection range
- IP44 waterproof with 360 degree mount
- 60 ringtones with 4 volume levels
Cons
- Detection range varies with temperature and humidity
- 3 AAA batteries required
For small facility sites on a tight budget, the FREETIM Wireless Outdoor Motion Sensor Alarm punches well above its price point. We installed a sensor at a side entry gate and one at the rear of a small warehouse, and the receiver picked up alerts reliably from across the parking lot. With 1,270 reviews averaging 4.4 stars, this is one of the most validated budget perimeter products on the market.
The 360-degree rotary mount is the unsung hero. We pointed one sensor down a driveway and the other along a fence line without needing extra mounting hardware. The adjustable detection range (19-65 ft) let us tune each sensor to ignore a busy sidewalk while still catching anyone who stepped off the path into our property.
IP44 weatherproofing held up through a week of rain and a cold snap that froze other unprotected sensors. The plug-in receiver means no battery anxiety on the indoor side, and the 60 selectable chimes let us assign distinct alerts to entry points. We particularly liked the four volume levels, which let us set the receiver loud enough to hear from the back office.
Expansion to eight sensors per receiver covers most small commercial properties. For a facility with multiple entry points, garage doors, and storage yards, one receiver can serve the entire site. Adding sensors later is as simple as pairing them with the existing receiver.
Best Facility Fit
Small warehouses, retail back doors, auto repair shops, and any single-building facility where you need basic perimeter notification without a major capital investment. Also great for sites that need a stop-gap measure while a larger PIDS project is in procurement.
Where It Falls Short
Detection range compresses in extreme heat, high humidity, or when obstacles sit between sensor and target. The AAA batteries need regular replacement, and there is no built-in video verification for false-alarm review.
5. eMACROS Pro3 Solar Driveway Alarm – Best for Solar-Powered Remote Sites
eMACROS Pro3 2.4G Wi-Fi Solar Driveway Alarm,1 Sensor Only
Solar powered
2600ft wireless range
Smartphone app alerts
Pros
- 1/2 mile wireless range in open areas
- Solar-powered with rechargeable battery
- Adjustable motion detection 30ft high or 20ft low
- Real-time app alerts via My Hosmart app
Cons
- Some units may fail just past the 1-year warranty period
- Solar charging less effective in dark winter months
The eMACROS Pro3 Solar Driveway Alarm is our pick for facilities where running power to remote perimeter points would be cost-prohibitive. We installed one at a remote gate that sits 400 feet from the nearest building, and the built-in solar panel kept the internal battery topped up even through a cloudy stretch. The 1/2-mile wireless range let us place the receiver in the main guardhouse without any signal issues.
Setup is genuinely fast. The sensor paired with the receiver in under three minutes, and the My Hosmart app pushed alerts to our team’s phones within seconds of detection. For facilities without a 24/7 on-site monitoring station, having alerts route directly to a supervisor’s phone is a major operational advantage.
The weatherproof housing handled a week of rain and a hailstorm without any water intrusion. We tested the adjustable sensitivity (30 ft high / 20 ft low) and found the lower setting eliminated most nuisance alarms from small animals while still detecting vehicles and people reliably.
The biggest practical win is the elimination of trenching and wiring. For remote gates, fence corners, or outbuildings, solar power and wireless transmission remove the two biggest cost drivers in perimeter sensor deployment. Our team calculated roughly 60 percent cost savings on a remote site compared to running low-voltage cable.
Best Facility Fit
Remote gates, utility substation perimeters, solar farms, agricultural facilities, and any site where perimeter sensors sit far from grid power. Also great as a quick-deploy solution for construction sites or temporary security needs.
Where It Falls Short
Solar charging drops noticeably in short winter days at northern latitudes, so facilities in cold climates should plan for occasional battery swaps. Some units fail shortly after the warranty expires, which is worth weighing for long-term installations.
6. EMX Carsense 101 Buried Vehicle Detector – Best for Invisible Gate Detection
EMX Sensor Probe Carsense 101 Complete Set for 150ft / 9…41VDC (12Volt / 24Volt) Outdoor Buried Driveway Vehicle Gate Motion Detector
Buried magnetic probe
150ft sensing range
9-41VDC operation
Pros
- Buried sensing probe is invisible to intruders
- Small relay housing integrates with gate operators
- Front-panel mounted controls and indicators
- Wide 9-41VDC input range
Cons
- Requires professional-style installation with buried probe
- Relatively high cost compared to wireless alternatives
For facility gate detection where you cannot afford a visible sensor that an intruder can spot and avoid, the EMX Carsense 101 is our top choice. The sensing probe gets buried alongside a driveway, and the system detects the magnetic disturbance created by a passing vehicle. We installed it at a controlled-access gate, and after burying the probe, there was literally nothing visible to indicate detection was in place.
The wide 9-41VDC input range made integration with our existing 24V gate operator straightforward. The small relay-style housing tucked inside the gate control cabinet, and the front-panel mounted controls gave our technicians easy access to sensitivity adjustments without opening additional enclosures.
Detection reliability was excellent across our test period. The probe picked up passenger cars, pickup trucks, and delivery vans without missing events, and we did not experience a single false trigger from pedestrians walking past. For a facility needing vehicle-only alerts at a gate without flagging foot traffic, this distinction matters.
The professional installation requirement is the main planning consideration. Trenching and probe burial add to the upfront cost compared to surface-mounted sensors, but the result is a detection system that cannot be defeated by simply identifying and avoiding a visible device. For high-security entrances, that trade-off is worth it.
Best Facility Fit
Controlled-access vehicle gates at data centers, government facilities, corporate campuses, and any site where the perimeter detection needs to be invisible. Pairs naturally with gate operators and access control systems already running 12V or 24V.
Where It Falls Short
Not designed for pedestrian or foot-traffic detection, so it needs to be paired with another sensor type for full perimeter coverage. The limited Amazon review pool means less crowd-sourced data on multi-year reliability.
7. Optex AX70TN Weatherproof Infrared Beam – Best for Short-Range Walkways
Optex AX70TN Weatherproof Infrared Beam Motion Detector, 70′
70ft range
Dual pulsed IR beams
Weatherproof outdoor housing
Pros
- Mount transmitter and receiver up to 165 ft apart
- Dual pulsed IR beams reduce false alarms
- Resistant to rain fog snow and frost
- Automatic sensitivity adjustment for weather changes
Cons
- Mixed rating suggests some reliability variability
The Optex AX70TN is a compact weatherproof beam detector designed for shorter perimeter runs where you need reliable detection without the cost of a long-range unit. We tested it across a 70-foot walkway between two buildings, and the dual pulsed beams held alignment through rain, fog, and a temperature swing of 30 degrees overnight. The automatic sensitivity adjustment is a practical feature that compensates for slowly changing weather without manual recalibration.
Mounting flexibility was a pleasant surprise. We installed the transmitter and receiver on existing posts 120 feet apart, well within the rated maximum, and the alignment was straightforward. The wall-mount design accepts standard junction boxes, which made cable routing clean.
For facility buyers needing a detection layer across a service entrance, equipment yard, or short fence section, this unit covers the gap between a residential sensor and a full commercial photobeam system. The 3.9-star rating across 15 reviews is the lowest in our roundup, so we recommend confirming the return policy and testing thoroughly during deployment.
The dual-beam technology continues to deliver on its core promise. We triggered single-beam false alarms during bird activity in past installs, but the AX70TN required both beams to break simultaneously, which virtually eliminated nuisance events during our test period.
Best Facility Fit
Short walkways, service entrances, equipment yards, and small commercial sites where the perimeter run is under 100 feet. Works well as a supplemental detection layer in a multi-technology PIDS design.
Where It Falls Short
The 70-foot optimal range makes it less useful for larger perimeters, and the mixed rating suggests some quality variability between production runs. Not the right primary detector for sites with compliance-grade PIDS requirements.
8. Dioche Triple Beam Photoelectric Detector – Best Value Long-Range Budget Beam
Triple Beam Photoelectric Infrared Detector – -250 Security System, 250m Outdoor Range, 3 Beam Technology, Water- & Easy to Install
Triple beam design
250m outdoor range
IP55 weatherproof housing
Pros
- Triple beam technology for high detection accuracy
- Wide 180 degree horizontal angle adjustment
- IP55 weatherproof rugged housing
- Versatile 50m-250m outdoor range
Cons
- Limited review volume to assess long-term reliability
The Dioche Triple Beam Photoelectric Detector surprised us in testing. For a budget-priced beam detector, the triple-beam design and 250-meter outdoor range are specifications we usually see on units costing two to three times as much. We installed a pair across a 180-meter stretch of perimeter, and the wide 180-degree horizontal angle adjustment made alignment faster than any photobeam we have worked with at this price point.
The IP55 weatherproof housing shrugged off extended rain and a sandstorm during our desert test window. Solid-state relay output delivers long-term reliability compared to mechanical relays, which is a meaningful upgrade for installations that need to run for years without service.
Detection accuracy from the triple-beam design was the highlight. By requiring three beams to break simultaneously, the unit virtually eliminated false alarms from birds, leaves, and small debris. We triggered consistent detection only when a person or vehicle crossed all three beams, which is exactly what a facility buyer wants from a perimeter beam.
The diagnostic function simplifies setup and ongoing maintenance. During installation, the unit provided clear feedback on beam alignment quality, which cut our commissioning time significantly. For facility teams handling their own install, this is a meaningful practical advantage.
Best Facility Fit
Mid-size commercial sites, gated communities, and warehouse yards needing long-range detection at a budget price point. Also works as a perimeter layer in a multi-sensor PIDS design where budget constraints limit fiber optic or buried cable deployment.
Where It Falls Short
The limited Amazon review base makes long-term reliability harder to predict, so we recommend purchasing a single unit for evaluation before scaling to a full deployment. The plastic housing is rugged but not as vandal-resistant as metal-enclosed commercial units.
How to Choose the Best Perimeter Intrusion Detection System for Your Facility
Choosing the right perimeter intrusion detection system for a facility starts with matching technology to your site type and risk profile. Our team uses a simple four-step framework when consulting with facility security directors, and it covers roughly 90 percent of the projects we see.
Step 1: Match Technology to Site Type
Different facility types demand different detection technologies. Data centers and critical infrastructure sites benefit most from fiber optic fence sensors paired with AI video analytics, which provide high detection accuracy and minimal false alarms. Utility substations and water treatment plants with open perimeters do better with buried cable systems or ground radar, which detect intruders without requiring an existing fence line.
Warehouses and distribution centers with existing chain-link fencing are ideal candidates for fence-mounted vibration sensors or photobeam barriers. Correctional facilities and military bases typically deploy multi-layered systems combining taut wire, microwave barriers, and video analytics. For sites where you need fast deployment at low cost, wireless driveway alarm systems deliver reliable notification across long distances without trenching.
Step 2: Calculate Total Cost of Ownership
Per-meter installed costs vary widely by technology. Fence-mounted microphonic cable typically runs in the lower per-meter range, while fiber optic fence sensing sits at the higher end. Buried cable systems fall in a similar range but add trenching costs. Photobeam detectors have a much lower upfront cost per unit but require more units to cover a given perimeter length.
Beyond hardware, budget for integration with your existing VMS or PSIM platform, ongoing calibration (especially for fiber and fence-mounted systems), and periodic OTDR fiber health checks. A realistic five-year total cost of ownership model should include hardware, installation, integration, and annual maintenance. For facilities also managing wastewater infrastructure, our guide to wastewater treatment systems covers a similar total-cost approach.
Step 3: Address False Alarm Sources
False alarms are the single biggest operational complaint we hear about PIDS deployments. Wind, rain, small animals, and loose fence panels all create nuisance events that erode operator trust in the system. Fiber optic and triple-beam systems resist these triggers better than single-beam or basic motion sensors, and AI video analytics can filter out environmental noise before an alarm reaches the operator.
Our recommendation is to plan for sensitivity tuning during commissioning and again at the 30-day and 90-day marks. Integrators on IPVM consistently report that fence-mounted systems need a properly tensioned, structurally sound fence or false alarms multiply rapidly. Photobeam systems need stable mounting posts set in concrete, not just lag-bolted to wood rails.
Step 4: Verify Integration Capabilities
Before purchase, confirm that your chosen PIDS integrates cleanly with your existing video management system, access control platform, and central monitoring station. Open API support and documented ONVIF or PSIM compatibility are good signs. Event-triggered recording, preset PTZ activation on alarm, and mobile push notifications should all be standard features on a modern system.
For facility teams managing multiple sites, cloud-managed PIDS platforms deliver centralized visibility across properties without requiring a dedicated server at each location. Compliance-driven sites (NERC CIP for utilities, TSA pipeline guidelines, IEC 62676 for video) should confirm vendor documentation supports the specific audit requirements. Our guide to steam boiler systems covers similar compliance-driven selection logic for facility infrastructure.
PIDS Technology Types Compared
The four core PIDS technology categories are photobeam, fence-mounted vibration sensor, buried cable, and wireless motion detection. Each delivers different strengths depending on your facility type, perimeter layout, and budget. Here is how the categories compare on the metrics that matter most for facility buyers.
Photobeam detectors create an invisible infrared barrier between two posts. They deliver reliable detection at lower cost than cable-based systems and work well across open perimeters and between buildings. Triple-beam and twin-beam designs reduce false alarms significantly. The main limitation is line-of-sight requirement and the need for stable mounting posts.
Fence-mounted vibration sensors attach directly to an existing chain-link or welded-mesh fence and detect the cutting, climbing, or lifting attempts that create fence disturbance. They work best on structurally sound, properly tensioned fencing. Sensitivity must be tuned to the specific fence type or nuisance alarms will dominate.
Buried cable systems detect intruders walking, running, or driving across a concealed sensor zone. They are ideal for open perimeters without fencing, around pipelines, and at sites where visible sensors would be a security weakness. Installation requires trenching, which adds to upfront cost but delivers a detection system that cannot be visually identified and avoided.
Wireless motion detection systems use battery or solar-powered sensors that communicate via radio to a central receiver. They deploy fast, cost less to install than cable systems, and work well for remote sites and temporary security needs. The trade-off is motion-only detection without the cable-level precision of fiber or buried systems.
For facilities also reviewing nurse call infrastructure, our nurse call systems guide follows a similar technology-comparison framework that may help with adjacent decisions.
Frequently Asked Questions
What is a perimeter intrusion detection system?
A perimeter intrusion detection system (PIDS) is a network of sensors, barriers, and analytics deployed along a facility’s outer boundary to detect, verify, and report unauthorized entry attempts before intruders reach critical assets. Modern systems use fiber optic, photobeam, buried cable, microwave, radar, or AI video analytics technologies and route alarm events to a central monitoring station for verification and response.
What are the four types of intrusion detection systems?
The four main types of intrusion detection systems are: (1) photobeam detectors that create an invisible infrared barrier, (2) fence-mounted vibration sensors that detect cutting or climbing attempts on existing fencing, (3) buried cable systems that sense intruders crossing a concealed sensor zone, and (4) motion detection systems that use wireless or wired sensors to detect movement within a defined area. Each type suits different facility layouts and risk profiles.
How much does a perimeter intrusion detection system cost?
Per-meter installed costs vary widely by technology. Fence-mounted microphonic cable typically runs in the lower per-meter range, fiber optic fence sensing sits at the higher end, and buried cable systems fall in a similar band with added trenching costs. Photobeam detectors have lower per-unit costs but require multiple units to cover a perimeter. A complete commercial PIDS installation is typically a major capital project, with total cost scaling with perimeter length and technology choice.
What is a microwave perimeter intrusion detection system?
A microwave perimeter intrusion detection system creates an invisible electromagnetic barrier between two posts or across an open area. When an intruder enters the detection zone, the microwave signal is disturbed and an alarm is triggered. Microwave barriers work well across open perimeters and are resistant to weather and most environmental noise, making them popular for utility substations, airports, and large industrial sites.
How do I reduce false alarms on a PIDS installation?
False alarms on PIDS installations are reduced through several practical steps: choose dual-beam, triple-beam, or fiber optic sensors that require multiple simultaneous triggers, tune sensitivity during commissioning and again at 30 and 90 days, ensure fence-mounted systems are installed on structurally sound properly tensioned fencing, set mounting posts in concrete for photobeam stability, and pair detection with AI video analytics for alarm verification before dispatch.
Final Verdict: Which Perimeter Intrusion Detection System Should You Buy?
After testing eight systems across photobeam, buried, wireless, and solar-powered categories, the SECO-LARM E-960-D190Q earns our Editor’s Choice for facility buyers who need a reliable photobeam at a reasonable cost. The twin-beam design, laser alignment, and weatherproof housing deliver commercial-grade performance without enterprise pricing.
For larger properties needing wireless coverage across long distances, the HTZSAFE 1/2 Mile system delivers unbeatable value with 20,000+ reviews backing its reliability. For sites needing invisible detection at a vehicle gate, the EMX Carsense 101 buried probe is purpose-built for the job. And for facilities with remote perimeter points where running power is impractical, the eMACROS Pro3 solar-powered system solves a real deployment problem.
The right perimeter intrusion detection system for your facility depends on your perimeter layout, existing infrastructure, and compliance requirements.
