There is no +12v feed from the head unit plug that is used for the DVD override unfortunately, or I would have spliced into that for you. You could tap into the +12v for the reverse camera.
Out of interest, how long does it take the wireless transmitter / receiver to sync up and start showing a stable picture (assuming that the video signal is already on)? Is it stable from the beginning, or does it take a short while to settle down?
Sorry, i didn't mean it that way around
Im not expecting a power feed
just the speed sensor and hand brake...
I was thinking more of attaching the switch (when i finally get my hands on one) to a relay of some sort to activate a multitude of sins including the bypass and handbrake ground and also to provide an on/off power switch too.... (maybe a stretch too far but I am on mission now
As for the sync time it is almost instant for my testing so far, however 9v battery life is Very short and even a small loss in power degrades the picture quality dramatically and had me thinking i had broken the camera in some way.... it was only during my fault finding, I swapped the battery and it came back to full quality!
so for your "bird watching"
you may want a mains feed to your remote cam
position or shares in duracell for the batteries... (or a solar charging station for it! OT but interesting concept)
I have actually bought two more wireless kits myself to set up security cams for covering my garage and garden as the quality was so good!
