Setup and Installation
The PJ-Cam1 camera is designed for easy installation on your bicycle's seat post. Please follow these steps carefully:
- Prepare the Seat Post: Ensure the seat post area is clean and free from obstructions. The camera mount is suitable for seat post diameters between 16-40 mm.
- Remove Old Camera (if applicable): If you are replacing an existing camera, carefully dismantle it from the seat post.
- Mount the New Camera: Slide the new camera mount onto the seat post. Position the camera approximately 5-10 cm (2-4 inches) below the top of the seat post, ensuring it is outside the saddle clamping area.
- Connect the Cable: Connect the AHD cable from the camera to your PARKVISION BK-430 screen. Ensure the connection is secure.
- Adjust and Tighten: Power on your BK-430 system and adjust the camera lens to achieve the desired viewing angle. Once satisfied with the angle, tighten the camera mount securely to prevent movement during rides.
