The Hikvision iDS-2CD7A86G0-IZHSY(2.8-12mm)(C) is an 8MP DeepinView bullet camera that records at 3840 x 2160 from a 1/1.8" progressive scan CMOS sensor, with DarkFighter technology giving colour images down to 0.002 lux. Its motorised 2.8-12 mm P-iris lens covers a horizontal field of view from 112.3° to 41.2° and can identify people at up to 21.6 m, while 850 nm smart IR reaches 50 m and 120 dB true WDR handles strong backlight. On-board deep learning detects human bodies, faces and vehicles simultaneously and compares faces against up to 150,000 entries across 10 libraries. Further analytics include perimeter protection with line crossing and intrusion detection, multi-dimension people counting, queue management, heat maps and hard hat detection. It offers H.265+ compression across five streams, electronic image stabilisation, a built-in heater, audio in and out, 2 alarm inputs and outputs, RS-485 and microSD storage up to 1 TB. Rated IP67, IK10 and NEMA 4X, it operates from -40°C to 60°C and is powered by PoE (IEEE 802.3at) or 12 VDC.
