How to use

Install the camera on a firm ceiling or wall surface positioned to cover the intended area. Connect the device to a LAN switch or PoE port according to your network design and assign an IP address via DHCP or a static configuration. Configure framing and zoom through the camera’s web interface or your video management software to set pan, tilt and zoom presets. Adjust image parameters such as exposure, white balance and bitrate to match lighting conditions and recording requirements.

Recommendations

For optimal results, mount the camera at a height that gives an unobstructed view of the scene and allows the 2.8–12 mm range to capture required detail. Use a PoE-enabled switch to simplify power and network cabling, and define recording schedules and motion detection zones in the VMS to reduce storage and false alarms.
