Thermal triggers on DS-2TD2628-10/QA bi-spectrum camera 

Accurate perimeter protection with AI Line crossing & Intrusion detection with the thermal lens.
The colour low-light lens provides the hi-res colour or B/W images for identification.
The triggers outside the fence will initiate the pre-recorded audio message and flashing white light (or constant on).
Off-site monitoring will then address the intruder live.
If not detered, armed response will be called and guided to the intruder.
