Monitor fixed security zones with 4MP network video from a compact dome camera built for installed surveillance coverage. INSIGHT S245ZI combines a high-resolution image sensor with infrared illumination, giving security teams a camera option for areas that require identifiable detail in daylight and usable coverage after ambient light falls. Its dome format suits ceiling or wall positions where the camera needs a contained, directional field of view. The motorized 2.7–13.5 mm varifocal lens distinguishes this camera from fixed-lens dome options. Adjusting the focal length changes the field of view and image magnification without opening the enclosure or physically moving the unit. That capability is useful when final camera positioning is constrained by mounting locations, conduit paths, or existing coverage requirements. The lens can be set wider for an approach or tighter for a gate, doorway, or distant point of interest. Infrared illumination reaches up to 30 m for low-light observation. Pair the camera with Ethernet network infrastructure and a compatible video-recording or monitoring platform to add it to a monitored IP surveillance environment. Its combination of 4MP resolution, IR operation, motorized framing control, and dome form factor makes it suited to locations where fixed coverage must be tuned accurately after installation.
