How to Tell if Your Home is Pre-wired for Security Many times a new homeowner is unaware that their home is pre-wired for security. In the video below, you will discover how to spot the alarm pre-wire.
As a reminder, what you are looking for in the bottom of your window frame is a small button looking contact, that is a little bit bigger than the end of your pinky. Sometimes, you may not see the contact, but will see a glob of silicone instead. If you see the silicone, you can be quite sure that the contact is below.
Hopefully this will help you determine if your home is pre-wired for security. If you are pre-wired, you should definitely install a hardwired system. A wireless unit will not make use of the existing contact points.
