vvhbad thing is that they didnt print product no. & sr no. on the box. I wrote them why it is? I checked manufacture date on cap of remote & it was oct 2010. I cant open a/c on it.As you mention when you recharge your a/c & inform to cc they activated recording service. You mean no need of any technical person to activate the service? It is my first time. Then why they dont active my DVR services?Thanks.
