This page will describe my work with yet another new transmitter and receiver purchased from Lawmate Technologies.  The units operate at  2.4ghz and the transmitter puts out 50mw.  A Panasonic CX161 Color CCD camera with pinhole lense is built in, and the whole shebang is powered by 9v.  The receiver is the same one included with Lawmate's 100mw transmitter and is powered by 12v.
Transmitter and Receiver: first impressions
I have come to the conclusion that pictures can never do a product justice, and you really need to hold it in your hand to appreciate it.  I say this because the integrated camera/transmitter was a lot smaller than I thought it would be.  I don't know why I thought it would be bigger but I did, and I was surprised.  Also, the case of the unit is heavy guage steel which gave it a good heft.

I've seen this unit offered by other companies and on ebay, and I believe they are all one and the same.  The only difference would appear to be the receiver that is bundled with them.  The hacks I talk about on these pages should apply to those other units, but I'm just guessing!
First mug shot of the camera/transmitter.  It's hard to see the ruler, but the marks on the side toward the camera are inches (it is 2.5 inches long)
Front shot of the camera/transmitter.  Pinhole lense is pretty tiny.  It's hard to tell from this picture, but there are two 'dents' on either side of the lense to facilitate focusing, since there really isn't anything else to grasp.
Back view of the camera/transmitter shows the 4 position switch for changing the frequency, SMA connected antenna, and power jack.
Here we jump right to the fully hacked system.  The transmitter pretty much falls right out of the case after removing the four screws on the sides of the camera that are hidden by the label.  Two small nuts held the power jack and antenna connector to the back part of the case, and unscrewing these allowed the back to easily come off.  The pinhole lense is integrated into the front of the case, so it remains attached to the CCD camera and actually affords a nice amount of protection for the CCD's components.  The white plastic cover on the antenna was hacked off to reveal a standard dipole, which was then covered in a length of heat shrink tubing.
I probably didn't gain much by removing the white plastic cover of the antenna, but it definitely made the antenna narrow enough to slip through a small hole in the plane's body.  All up weight of the system, minus the battery, is 1.6 ounces!  Not bad for just pulling the case off.
