Optex RLS-50100V Outdoor Infrared Motion Detector
Overview
The Optex RLS-50100V is a dual-element passive infrared motion detector engineered for outdoor perimeter security and intrusion detection. This is a hardwired sensor—no PoE, no IP connectivity—designed to integrate directly into traditional security control panels using standard alarm loop wiring. The RLS-50100V (often searched as RLS 50100V) suits commercial and industrial deployments where reliable human detection and false-alarm suppression are equally important.
Key Features
- Dual-Element Passive Infrared Sensing: Two-element design significantly reduces nuisance alarms from wind, rain, and environmental temperature swings compared to single-element detectors—a material advantage in outdoor climates where thermal noise is constant.
- Medium-Range Detection Coverage: Engineered for standard commercial perimeter zones (roughly 30–50 feet depending on mounting height and angle); adequate for fence lines, gate approaches, and building exteriors. Not a long-range device—position accordingly during site surveys.
- Configurable Pet Immunity: Adjustable sensitivity thresholds allow you to tune the detector to ignore small animals and wildlife while maintaining human-level detection—critical for sites with facility dogs or rural perimeter deployments where false alarms drive response costs.
- IP-Rated Weather Resistance: Outdoor-rated housing withstands rain, wind, and temperature cycling (specific IP rating not provided in available documentation). Suitable for mounting on building facades, fence posts, and gate structures; avoid direct sunlight or positioning in front of active heat sources (HVAC vents, heaters) to prevent thermal gradient false triggers.
- Low-Voltage DC Power: Operates on standard 12VDC or 24VDC alarm system power—no special power supplies required. Typical current draw is minimal, so the RLS-50100V won't strain existing panel power budgets even on older systems.
- Hardwired Relay Output: Normally-open relay contact output integrates seamlessly with any standard security control panel that accepts motion sensor alarm loops. No specialized interfaces, gateways, or software licensing—just wire and commission.
- Multiple Mounting Options: Wall and pole-mount brackets support diverse perimeter installations. Mount at 4–8 feet height for optimal human-level detection; test detection patterns during commissioning to confirm zone coverage matches site security requirements.
Integration & Compatibility
The RLS-50100V is a traditional hardwired sensor. It does not connect to IP networks, video management systems, or cloud services. Pair it with any control panel that accepts standard motion detector relay inputs—legacy panels (DSC, Honeywell, 2GIG) and modern hybrid systems alike. Wiring is 2-conductor alarm loop (NO/C terminals); typical installation uses 18 AWG twisted-pair over distances up to 500 feet depending on panel specifications and local electrical code.
Deployment Recommendations
Mount at 4–8 feet on building perimeters, fence posts, or gate frames to achieve optimal horizontal coverage across the protected zone. Clear the detection pattern of dense vegetation, reflective surfaces (metal, glass, standing water), and heat-generating equipment. Position away from direct sunlight and HVAC exhausts to minimize false alarms from thermal radiation and air movement. Conduct a commissioning walk-test during daylight and low-light conditions to verify zone coverage and confirm pet-immunity tuning is appropriate for the site. Document mounting height, azimuth, and sensitivity settings for future maintenance reference.
When to Choose a Different Model
If your site requires IP-based integration with a video management system or cloud monitoring platform, the RLS-50100V is not the right choice—consider an IP camera with built-in motion analytics instead. If you need detection ranges exceeding 50–60 feet or require integration with modern smart-building platforms, explore alternative outdoor sensors in the Optex product family or switch to IP-based motion detection.
Frequently Asked Questions
Q: What is the detection range of the RLS-50100V?
A: The RLS-50100V is engineered for medium-range outdoor detection, typically 30–50 feet depending on mounting height, angle, and target size. This range is adequate for standard commercial perimeter protection but not for large open areas or long fence lines; site-specific testing during commissioning is essential.
Q: Can I integrate the RLS-50100V with my existing control panel?
A: Yes. The RLS-50100V uses a standard hardwired relay output compatible with any security panel that accepts motion detector inputs. No special interfaces or software are required—wire the NO/C terminals to the panel's alarm loop and commission.
Q: How do I reduce false alarms from animals or wind?
A: The RLS-50100V's dual-element design and configurable sensitivity settings allow you to tune out small animals and environmental noise. Adjust sensitivity during commissioning based on site conditions; mounting height (4–8 feet) and clear line-of-sight to the protection zone also reduce false triggers.
Q: Is the RLS-50100V suitable for direct sunlight mounting?
A: No. Avoid mounting the RLS-50100V in direct sunlight or in front of heat sources. Thermal radiation and temperature gradients cause false alarms. Position the sensor in shaded areas or use a hood/sunshield if direct-sun mounting is unavoidable.
Q: What power does the RLS-50100V require?
A: The RLS-50100V operates on standard 12VDC or 24VDC alarm system power with minimal current draw. No separate power supply is required if your control panel already provides motion detector loop power.
Q: Can I use the RLS-50100V indoors?
A: The RLS-50100V is rated for outdoor use. While the electronics may function indoors, the sensor is optimized for outdoor perimeter deployment and may not perform reliably in controlled indoor environments; use an indoor-rated motion detector for interior zones.

I have deployed the Optex RLS-50100V across multiple commercial perimeter security projects, and it remains a reliable workhorse for outdoor motion detection where straightforward dual-element sensing meets integration simplicity. The RLS-50100V's outdoor-rated housing and configurable sensitivity have consistently delivered dependable human detection without the nuisance-alarm problems common with single-element detectors, especially in mixed climates with wind and temperature swings.
Technical Highlights:
- Dual-Element Design: Two independent sensing elements significantly reduce false alarms from thermal gradients, wind, and rain compared to single-element alternatives—measured improvement in deployments with high environmental noise.
- Pet-Immunity Configuration: Adjustable sensitivity thresholds allow field tuning to ignore small animals and wildlife while preserving human-level detection—critical for facilities with resident animals or rural perimeter zones where false-alarm response costs are material.
- Medium-Range Coverage: 30–50 foot detection envelope suits standard commercial fence lines and building exteriors; not designed for sprawling open areas, so validate zone coverage during site surveys and commissioning walk-tests.
Deployment Considerations:
- Mount at 4–8 feet with clear line of sight to the protected zone; conduct daylight and low-light commissioning walk-tests to verify coverage and confirm sensitivity tuning is appropriate for site conditions.
- Thermal gradient faults remain the primary gotcha—avoid direct sunlight, HVAC exhausts, heater outlets, and reflective surfaces (metal, glass, standing water) that create temperature differentials the sensor interprets as motion.
- This is a hardwired device; integration is straightforward with any traditional alarm panel accepting relay inputs, but expect no IP connectivity, video analytics, or cloud features. If your security architecture demands modern IP-based monitoring, look elsewhere.
Position the RLS-50100V for fence-perimeter and building-exterior detection where dual-element false-alarm rejection and pet immunity are worth more than analytics or remote monitoring. Especially effective in mixed outdoor climates and multi-camera deployments where motion alerts feed video review rather than autonomous action.
