Door phone systems are one of the best ways to protect your home from intruders. They give you the ability to speak with someone at all times of day, to check in on your home, or make sure no one is inside. Door phones also give you peace of mind when you’re away from home or otherwise unable to be present for an event that might require a response.
When installing door phone systems, it’s important to consider how they will be used. Will you need to call out and talk? Or will you only need to listen in? Regardless, it’s important that they work as intended throughout their lifetime. If they ever stop working, it could mean trouble for you and your family.
The most common type of door phone system is a traditional analogue dialing system . This means that the door phone will have a big rotary dial with numbers on it. To make a call, you would turn the dial until the number you wanted was lit up. The other end would then pick up the call, and dial the number back manually if necessary. This type of system requires a dedicated line for each phone, so if there are any additional phones in your home, they must have their own separate lines as well.
