- Strip the outer jacket and braided shield from the end of the main cable.
- Cut the branch cable to the desired length.
- Strip the outer jacket and braided shield from the end of the branch cable.
- Use a coaxial cable splice connector to connect the branch cable to the main cable.
- Wrap the splice with electrical tape.
Connecting the Splice to the Camera
Once the splice is complete, you need to connect it to the camera. This involves attaching a coaxial cable connector (BNC or RCA) to the end of the splice.
Attaching a BNC Connector
To attach a BNC connector:
- Cut the cable to the desired length.
- Strip the outer jacket and braided shield from the end of the cable.
- Twist the central copper wire to the center pin of the BNC connector.
- Use a wrench to secure the connector to the cable.
Attaching an RCA Connector
To attach an RCA connector:
- Cut the cable to the desired length.
- Strip the outer jacket and braided shield from the end of the cable.
