This Hikvision PTR dome captures 4MP images at 2688 × 1520 from a 1/2.9-inch progressive scan CMOS sensor through a fixed 2.8mm lens with a 100.2° horizontal field of view. Its SMC+ 30% glass fibre polymer housing carries C5 and NEMA 4X anti-corrosion ratings alongside IP68 water and dust resistance and IK10 vandal resistance. ColorVu with Smart Hybrid Light combines 850nm IR and white light with a range of up to 40m for colour imaging down to 0.001 lux, while 130dB WDR keeps detail against strong backlight. Motorised pan, tilt and rotate allows the view to be adjusted remotely, and deep learning perimeter protection covers line crossing, intrusion and region entrance or exit, filtered to humans and vehicles. An active white strobe light and built-in speaker (105dB at 10cm) warn intruders off, and two built-in microphones support clear two-way audio. The camera is powered by 12V DC or PoE (IEEE 802.3at, max 21W) and supports ONVIF Profile S, G and T, ISAPI and ISUP.
