Digital Watchdog DW-DTLA500 Outdoor Laser Perimeter Sensor
The DW-DTLA500 is an eye-safe infrared laser detector designed for outdoor perimeter protection and intrusion detection. It delivers 500-meter detection range with ±1 decimeter positional accuracy—critical when you need to pinpoint exactly where a breach occurs across loading docks, fence lines, or secured compounds. The 905nm wavelength is Class 2 eye-safe, meaning it meets international laser safety standards without requiring exclusion zones or warning labels.
Overview
This sensor operates as a standalone detection device or integrates into larger security systems via relay contacts (NC/NO, max 30V 200mA) and Ethernet reporting. The 250 Hz update rate catches fast-moving intrusions; the narrow 2.0 × 2.0 millirad beam divergence keeps false alarms low in high-traffic or weather-prone areas. Power via standard PoE (802.3af at 48 VDC) or dedicated 12 VDC supply—4W consumption fits either infrastructure without strain. IP66 rating handles direct rain, dust, and salt spray; operating range -30°C to +60°C covers most climates.
Compatibility
The DW-DTLA500 integrates with any security system that accepts relay switch inputs—traditional analog panels, modern access control hubs, and ONVIF-capable video management software via its Ethernet port and TCP/IP interface. Web browser configuration allows remote zone setup without field visits. Relay output (NC and NO contacts) connects directly to door controllers, sirens, or NVR alarm inputs.
Installation Notes
Mount the sensor in clear sight lines across the protected boundary—trees, vehicles, and dense brush degrade detection. The narrow beam requires precise aiming; use the web interface to verify coverage after installation. Enclosure dimensions are 130 × 120 × 250 mm (gray shell, black sensor head); weight is 2.4 kg, suitable for pole, wall, or tripod mounting. Operating temperature swings between -30°C and +60°C without recalibration. Configure up to 20 fully adaptable alarm zones per sensor to ignore trusted paths (delivery gates, maintenance corridors) while protecting perimeter.
