the placement of the monitor on the car dash/windshield seems to be a hit-or-miss operation for a 2.4GHZ device needing to transmit a signal no more than 8-9 feet. BTW- i do not use a bluetooth device or have aftermarket electrical accessories or a license plate cover. i tested and do not have alternator/ignition interference. i did not cut/shorten the length of the wires in case the wire length could/may add to transmission/reception, but bundled the extra length to prevent the wires from being exposed or dragged along the pavement (using the zip tie provided).
at first i tried placing the wireless camera on the lower part of my license plate and used the cig lighter power adapter for the monitor. i mounted the monitor's swivel base onto the front window - behind the rear view mirror. i installed the camera power to a 12V license plate light line (used the provided clips and covered all in electrical tape) to give me more frequent use of my investment. (this thing is not inexpensive.) i had good reception and enjoyed the wide-angle view across 3 lanes of traffic. BUT, i had to put up with very annoying horizontal lines and 1-2 second screen shutoffs at least every minute. additionally, when i'm in a covered parking garage, passing under highway bridges, or going under some (not all) overhead, city street electrical lines, there is interference.
i often wonder, which direction is this camera transmitting it's signal? are there vulnerable signal transmission points along the wiring? does the monitor need something 'extra' (like a directional antenna) to work right in a wireless mode - even at only half the distance of recommended/limited operation (9 ft. vs. 19 ft.)?
so next, i moved the camera to the top part of the license plate to shield it from "whiteouts" caused by the (not-so-harsh, but too-bright-for-the-camera) winter sunshine when the sun is over the back of my car. i like the camera placement and plan to keep it at the top of the license plate. since the monitor is now placed at eye-level at the far left side of the windshield, i hard-wired it to my interior fuse box (using the turn signal terminal) and grounded it to an unpainted, metal body section w/bolt. hard-wiring was necessary since the cig lighter power adapter cord is too short to be of any use for left-side dash monitor placement.
now i am totally frustrated because the reception is "snowy" and the horizontal lines and screen shut-offs are quite frequent. BTW-the monitor still has the freedom to move on it's stand, but re-aiming it never makes a difference.
so they got me...another 20 bucks for the "proprietary" hard-wire plugs for the monitor. what's the use of this "wireless" camera if it cannot broadcast a 2.4GHZ signal 10 feet? i'll also be interested to see if the tech support people automatically consider this post to be "solved" since i ended up buying something extra to get it to work (i hope).
Update 3/13/08 - wasted my money ($20) on the proprietary cord they sent me. it does not come with a separate power supply line, so it is basically useless! the tiny lcd monitor only has one connector, and it is for power only, not for signal transmission! inside the lcd is the receiver with a 2-inch, 16-guage wire antenna. the transmitter is a 1d foot, 18-guage wire in the camera cable and is covered by tough plastic. so, there is no easy way to use the cord to connect the transmitter to the receiver!!!! aaaahhhhhhhhh!! bad customer service to tell me that it will work!!
