Model Code: DS-2CD3746G3T-IZSUY(Black)(B)
Hikvision DS-2CD3746G3T-IZSUY(Black)(B) Black 4 MP Motorized Varifocal Dome Network Camera
4 MP dome network camera with a motorized varifocal lens, 130 dB WDR, IR illumination and alarm triggering by human or vehicle targets. Includes a built-in dual-microphone array and local memory card storage.
Product description
The maximum image resolution is 2688 × 1520. Image processing includes 130 dB WDR, BLC, HLC and 3D DNR. An IR cut filter and automatic or scheduled day/night switching are supported.
A motorized varifocal lens, auto-iris and smart IR illumination are supported. The technical table lists field-of-view and IR illumination values by lens configuration.
Line crossing, intrusion, region entrance and region exiting detection support alarm triggering by human and vehicle targets. A built-in dual-microphone array captures audio, with line input and line output also provided. Scene changes, audio exceptions and defocusing can also be detected.
The main stream supports H.265, H.264, H.264+ and H.265+ compression. The built-in card slot accepts microSD/microSDHC/microSDXC cards up to 512 GB. Protection ratings are listed as IP67 and IK10. Anti-corrosion protection is specified as NEMA 4X (NEMA 250-2018).
