Indoor PTZ Camera
The CNB S1765N is an indoor speed dome PTZ camera built for CCTV surveillance systems that rely on analog infrastructure. It suits installers and facility managers who need remote directional control and zoom capability from a single ceiling-mounted unit. Buyers who want more storage or network streaming will not find those functions here.
27x Optical Zoom
The single specification that decides fit is the 27x optical zoom combined with 10x digital zoom for 270x total magnification. This range lets operators close in on distant detail without moving the camera. If the site requires wider zoom reach or a different optical ratio, this model will not match the requirement.
Sustained Operation
Under continuous pan, tilt and zoom activity the 1/4" Sony Super HAD CCD maintains 480 TVL resolution while the ICR and DSS functions adjust for changing light. The camera supports 128 presets and 8 swing patterns for automated tours. Protocols include PELCO-D and P Protocol for integration with existing controllers.
