I am installing CCTV cameras and I'm using a 3A adapter to supply power to the cameras, but I have very messy results when trying to join together very small wires with electrical tape.
Is there any clean way of doing all this? For example, how can I join together the wires of 3 power supply cables? Also, how to join the Audio/Video lead to the normal wires? I find it very hard to first cut the A/V cable and then use electrical tape to join them.
I want to make something like this, but it's not as clean. It looks messy with electrical tape.
