Hikvision DS-2CD3746G2H-LIZSU/SL(Y)(PTRZ) 4 MP Motorized Dome Camera with Light and Audio Warning
This dome camera combines remote angle adjustment, a motorized varifocal lens and dual illumination. It includes built-in microphones and a speaker, plus audible warning and white flashing light.
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. The manufacturer specifies a maximum of 1000 cycles for remote angle adjustment.
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. Built-in microphones and a speaker are provided, with audible warning and white flashing light supported.
Local recording supports microSD/microSDHC/microSDXC cards up to 512 GB. Power options are 12 VDC and PoE. The manufacturer lists IP66 water/dust protection and IK10 impact resistance.
