I have my receiver upstairs and I can not pick up ANY signal AT ALL from my motion detectors outside for my cameras.... your help is greatly appreciated...............thanks!!!!

Motion sensors are outside and on all four corners of the house. The reciever is upstairs. so signal has to go through the floor and at least one wall
-
My newest TM751 [was in a bundle deal] has the same receiver PC Board in it as the CM15A, but with the metal antenna. Beats the CM15A by a long shot. :)%
The mod for the CM15A found on accessha.com is not accessable any more. I believe the site has closed down. :(

Here is a CM15A mod similar to the one on accessha.com had on their site.

Maybe we should have a section in our Forum or somewhere else for all those great shots and step by step pics that some are so dependable on including myself. Telling me how to do something is one thing, show me is much more effective.

Thanks for the new link. Yes they sure look similar. Just a few added photos of details.

1. I don't know of any mods for the CM19A.
2. Even if the CM19A does receive the RF signal from [say] an "eye" motion detector.... the CM19A doesn't put a signal on your power line (PLC). Camera power supplys respond to the PLC... not RF. So there would be no way for the [eye] motion sensor to turn a camera on.

when a motion sensor is triggered in the Vanguard software, the camera that is currently selected is powered off and the one that is assigned to the motion sensor that is tripped turns on, and you can have stills or video recorded and emailed.
Problem is, I cant get the signal from the motion sensor to the CM19A......I got 2 of them to work, but no go on the other 2.

The CM19A is USB and the MR26A is serial port connected.
The CM19A is both a receiver and transmitter for X10 RF signals. By what the web page said and I found a schematic on the FCC site that also shows both a receiver and transmitter section.
The MR26A is a receiver only. There was no data on the FCC site for the MR26A.
Since the CM19A also transmitts. You would have to be careful not to detune it as X10s output section is kind of skimpy on parts and you would void the FCC Acceptance. Probably would send farther though
