OK - here's a question for the more technically inclined folks out there.
I have been looking for an affordable
rear-view camera to install on the back of the TT. If anyone else out there has looked for an affordable
unit like this, they know that they don't exist.
So, I've been brainstorming a way to do this with less expense. Here's my idea. If anyone out there can tell me why it might not work - and if so how to make it work, I'd appreciate it.
Harbor Freight tools sells these little outdoor security cameras:
The specs indicate that they run on 9 VDC /200mA.
Radio Shack sells the following 12v to 9v adapter:
This unit runs at 1000mA.
I'd plan to run a line to the tow vehicle with a seperate wiring plug to handle the power and the video feed.
I'd run the video into a small LCD monitor that I'd attach to the dash or the window (similar to the GPS mounts) lsimilar to this:
Total cost on this will be about $150.
Here are the questions I have:
1. Is there an issue running an adapter that puts out 1000mA when the camera runs at 200mA?
2. With the very long run from the rear of the TT to the tow vehicle (probably around 40+ feet) will I have an issue with the power over such a long line, or with the video signal?
If anyone sees any other potential technical issues, I'd love the feedback.
