"Often does not work, needs to connect units by wire."0.5 starson by mbtbd
Pros: Easy to install, but wasted time as the unit often does not work.
Cons: Very unreliable, even though this is not even wireless.
Summary: Very disappointed with this product and thought at least my wasted time in installing it would be worth something if I could give you all a warning: quite simply the audio often does not work, and when it does, the sound of anyone outside is very quiet, even if they are speaking right into the mic. The video will also sometimes turn of when you push the talk button, Push to talk button often won't work, etc. Very unreliable, don't waste your time like I did! (Only by knowing that I have given others fair warning, can I feel this was not a complete waste of time)
