AHP only recognises the VA11A!
I think you may have miss read a post which suggested using a module to turn on/off the video receiver, or create modules for cams if one didn't have the iWitness plug-in.
Now you could use thirdparty software to view your cams and trigger those to open when motion was sensed.
You could get
X10dispatcher to send the pics to a site,e-mail,MSN
You can also find the VA11A on E-bay for about $7-$15
