S15D
The flexible video cabling, weatherproof design and tiny footprint allows the two S15D thermal sensor modules to be installed into any location up to two meters away from a single S15D core unit. The advantage of using thermal sensor modules is that they can visualize heat radiating from vehicles and persons, for the purpose of accurate movement detection up to 400 meters away from the camera, even under the most challenging lighting and environmental conditions.
