A:AnswerHi! Yes, you can connect your antenna to this converter box and then to an HDMI jack on the TV. To get a better picture, please check page 9 of the user manual available on Best Buy's website.

A:AnswerNo... This is a digital receiver that is basically the same as your buit-in TV reciever but meant to connect to devices like projectors that do not have built-in digital receivers. With digital, you either have a usable signal or you have no reception.
A:AnswerI do not use the converter box to play VHS tapes. I connect the VHS player directly to the tv. I only use the converter to take the digital tv signal from the air and convert it to analog for my old analog tv.
A:AnswerMy Vizio TV has only HDMI slots. I hooked an antenna to the coaxial input on the box with RG-6 cable & an HDMI cable from the box to HDMI 1 on the TV & it works fine. It sounds like it would work fine for your camera system if you need a coaxial input. I hope this helps you.
