Model Code: DS-2CD3746G3T-LIZS
Hikvision DS-2CD3746G3T-LIZS 4 MP Dual-Light Motorized Dome Network Camera
A dome camera with HIK AI-ISP image processing, a motorized varifocal lens and dual illumination. It offers electronic image stabilization, perimeter analytics and local memory-card recording.
Product description
The camera provides a maximum resolution of 2688 × 1520. Its 130 dB WDR is complemented by backlight compensation, highlight compensation and defog functions. The main stream supports H.265, H.264, H.264+ and H.265+ compression.
The motorized varifocal lens has a specified range of 2.7 to 13.5 mm. Infrared and white supplemental illumination provides a range of up to 40 m, with smart supplemental lighting also supported.
Line crossing, intrusion, region entrance and region exit detection support alarm triggering for human and vehicle targets. Face capture and people counting are also available. An integrated microphone array is accompanied by line-level audio input and output.
Local recording supports microSD/microSDHC/microSDXC cards up to 512 GB. Power options are 12 VDC and PoE. The manufacturer lists IP67 water/dust protection and IK10 impact resistance.
