Door Entry Systems, Special Circuits

You'll find here everything you need to set up a door paging or entry system, with the exception of electronic door locks. Typically, you would get these from your local locksmith and more than likely have them mount them in the appropriate spot as it is not easy for the do it yourself. The idea here is a person comes to the door, they hit a button, and, the button rings a phone or phones. When you answer, you are talking to the person at the door. With the nicer controller, you can then enter a code (which can only be done INSIDE, not from a tone generator outside) which allows them entry by unlocking the door. Optionally, you can hook up a security camera so you can also see them. You can save quite a bit of money buy buying the items online even if you hire someone to install all of the equipment.
