  4. Works Great!!!

    Posted by N******t on 11th Dec 2012

    First of all, shipping was REALLY fast! I paid for expedited shipping which according to this website usually takes a week. But, the item arrive to Tennessee in the United States in 2 DAYS! It was really fantastic!

    Before I go into my personal use of the board, I want to say that everything on the board works EXACTLY as it should, it's a fantastic product!

    I used this product to control a garage door opener. Basically, I set it to the same address as the users PTZ camera. The PTZ camera doesn't have an iris adjustment. I have a 24v AC to 12v DC adapter connected to the Iris and Common terminals on this board. Then the 12v DC is connected to a relay that closes a connection to the switch on the garage door opener. So when the user presses one of the iris buttons, his garage door opens.
