Product description
Hikvision specifies a maximum resolution of 2688 × 1520 for DS-2CD3746G2HT-LIZSU(1T). When assessing the detail required in a scene, compare this figure with the image stream options documented in the technical table.
The manufacturer describes the lens configuration as: Varifocal lens, motorized lens, 2.7 to 13.5 mm and 7 to 35 mm optional. Check the lens configuration when planning the mounting position and coverage area; options listed for the family do not imply simultaneous lenses.
The listed supplementary illumination type is IR,White Light. The manufacturer gives the illumination range as: Up to 40 m. Assess these specifications alongside lighting conditions and objects that may obstruct the view at the installation site.
Basic event functions include motion detection supporting alarm triggering for human and vehicle target types. Plan detection areas and alarm notifications around the events that the installation needs to monitor.
The manufacturer lists a protection rating of IP67. Before installation, check the housing, connection points and mounting conditions against the official product documentation; the rating should not be treated as an unconditional guarantee for every operating environment.
