Hikvision DS-2CD3746G2HT-LIZSUY(256G)(7-35mm) 4 MP Motorized Dome Network Camera with SSD Storage
A dome camera with SSD storage configurations and motorized lens options. Dual illumination, built-in microphones and human/vehicle perimeter functions combine local recording with event-based monitoring.
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 specification table lists 2.7 to 13.5 mm and 7 to 35 mm motorized varifocal lens options. Infrared and white supplemental illumination supports a range of up to 40 m. Automatic, semi-automatic and manual focus modes are available.
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 are accompanied by line-level audio input and output.
The storage table specifies a built-in 1 TB SSD for the 1T model and a built-in 256 GB SSD for the 256 GB model. Both configurations support 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. The NEMA 4X claim in the corrosion-protection table applies only to the -Y version.
