Would have to agree. You could go with an all IR system and use Xantech products, which include power, video, audio, voltage, light, and temp sensors. Take a look at the http://www.xantech.com and find the GateKeep-ir system. This set-up would end costing slightly more than an IRF-6 with modules. E-mail me for pricing if it's attractive to you.
