Hikvision DS-2CD3766G3T-IZSU(B) 6 MP Motorized Varifocal Dome Network Camera
This 6 MP dome network camera combines a motorized varifocal lens, 130 dB WDR, an integrated dual-microphone array, perimeter protection analytics and memory card support.
Product description
The camera uses a 1/2.4" progressive-scan CMOS sensor and supports a maximum resolution of 3200 × 1800. At this resolution, the main stream is specified at 25 fps with the 50 Hz setting and 30 fps with the 60 Hz setting. Image processing includes 130 dB WDR.
The camera combines a motorized varifocal lens with auto-iris. For the 2.7-13.5mm lens of this variant, the technical table specifies an IR illumination range of 40m; the illumination rating depends on the lens configuration.
Perimeter protection covers line crossing, intrusion, region entrance and region exiting, with alarm triggering for human and vehicle targets. Face capture and people counting are supported. Smart events also include scene change, audio exception and defocus detection.
An integrated dual-microphone array and environmental noise filtering support audio capture. The main stream offers H.265/H.264/H.264+/H.265+ compression. The card slot supports microSD/microSDHC/microSDXC cards up to 512 GB, alongside documented NAS and ANR network storage functions.
The camera has a metal enclosure and can be powered by 12 VDC or IEEE 802.3at PoE. The technical table specifies IP67 and IK10 protection ratings. Startup and operating conditions are -30 °C to 60 °C, with humidity of 95% or less, non-condensing.
