The DeepinView DS-2TD2117-3/V1 Outdoor Thermal Network Bullet Camera from Hikvision uses a vanadium oxide uncooled focal plane array to capture 160 x 120 resolution video that can be upscaled to 320 x 240 resolution. The camera's 3.1mm fixed thermal lens provides a 50 x 37.2° field of view. Smart features include line crossing, intrusion, region entrance/exit with human and vehicle filtering, temperature exception, early warning fire prevention, advanced fire detection, and cigarette smoking detection. Two-way audio communication is possible thanks to an audio input and output. An onboard memory card slot accepts microSD/SDHC/SDXC cards up to 128GB (available separately). Integrated PoE technology simplifies connectivity by enabling the transfer of power and data through a single cable.
