My pleasure, I assume you are ok with using a volt meter and such. We aren’t talking about anything sophisticated. Basically, find a USB power cable that you know works with the WyzeCam. You want to make sure it is working before you start so you aren’t trying to troubleshoot a bad cable.
- Take a working USB power cable (I would suggest minimum of 12 inches) and cut it in half
- Strip back the wire approximate 1 inch on each half, you may need more later depending on how you splice in you existing wiring
- Plug the power side (not the end that goes into the camera) into your power source, making sure that your 4 or 5 wires are touching each other.
- Using your volt meter confirm which two are the 5 volts, most likely it will be the red and black wire. You need to make sure you know which is positive and which one is negative
- Once you determine that, you can now pick two wire from your internal wiring to connect the USB positive and negative to. (of course, you must make sure you have disconnected the other end from your alarm panel or where ever it was connect to be fore you start this step)
- I would start with the power end of the cable (the part that plugs into the USB power block.
- Ensuring that the two wires on the camera end of the cable aren't touching, plug in the power in and use your volt meter to confirm that you have the right two wires and that you are getting 5 volts, also confirm which one is positive and which is negative.
- Once you confirmed you have power at the camera end, disconnect the power, splice in the cable that plugs into the camera
- Plug in the power end, then I would plug in the camera. That way you can watch the camera and make sure it powers up
I hope that helps. It is only 5 volts but you want to make sure that you don't have a short anywhere. I have been good up to about 75 feet but that has only been a guess.
I have 6 (3 inside and 3 outside) cameras and 2 Amazon Dots wired this way without any problems. I plan on adding about 5 more using this same method. 2 of my inside cameras are actually daisy chained off each other without any issues at all.
Please feel free to post again if you have any questions or if I can help with anything else. By the way, I get my cables from Monoprice, they are cheap and I can get short ones in either white or black…
