Setup
1. Planning Installation Location
Choose a suitable location for your camera, considering the desired viewing area, proximity to an NVR or PoE switch, and protection from direct impact. The camera is IP67 weatherproof, making it suitable for outdoor use in various conditions.
2. Mounting the Camera
- Use the provided positioning sticker to mark the drill holes on the mounting surface.
- Drill holes according to the marks. Insert wall anchors if mounting on masonry.
- Secure the camera base to the mounting surface using the screws.
- Adjust the camera angle to cover the desired area.
3. Connecting the Camera
The LP8MEF8 camera uses Power over Ethernet (PoE) for simplified connectivity.
- Connect one end of an Ethernet cable to the camera's PoE port.
- Connect the other end of the Ethernet cable to a PoE-enabled NVR (Network Video Recorder) or a PoE switch.
- Ensure the NVR/PoE switch is powered on. The camera will receive power and transmit data through this single cable.
