Tired of blind spots that let intruders slip by? The Hikvision DS-2TD2138-25/QY Wired IP Security Camera Outdoor 35 mK 0.48 mRad gives you clear thermal vision even in total darkness. It is built for tough outdoor sites where normal cameras fail, so you can see heat signatures, stop theft, and catch fire hazards before they become emergencies.
Hikvision DS-2TD2138-25/QY Wired IP Security Camera Outdoor 35 mK 0.48 mRad
Large facilities often struggle with perimeter defense and early fire detection because traditional video cant see through fog, rain or darkness. Missing a heat source can mean a costly breach or a dangerous blaze. This camera solves the problem with a high-sensitivity thermal sensor, anti-corrosion coating, and IP67 protection, delivering reliable images in any weather and alerting you to temperature changes instantly.
Benefits
- Detects human and vehicle heat signatures up to 3.2 km, giving you early warning.
- Thermal sensitivity of 35 mK shows even the smallest temperature differences.
- Works day and night, in rain, dust, or extreme temperatures.
- Integrates with Hikvision iVMS-4200 and Hik-Connect for easy monitoring.
- Low power draw and PoE support keep installation simple and cost-effective.
Usages
Install the camera at airport runways to spot unauthorized vehicles at night, on railway lines to catch trespassers before they reach tracks, or around prison walls to prevent escapes. Power stations benefit from early fire detection, while 4S stores use it to protect valuable inventory in outdoor parking lots. Anywhere you need reliable heat detection in a harsh environment, this camera fits the job.
