What to know if you bought a home with a security system


If you bought a home with a security system, it may be possible to reprogramme it and save money by replacing outdated technology with modern equipment like motion sensors and add equipment that you can be monitored.

You might have already done this when moving into the property; however, if not then it’s worth doing so now. Reprogramming involves making sure that all of your sensors are working and linked up correctly on your network as well as making sure any new additions (such as additional motion detectors) are connected to the network too.

Update the system – modernize.  A modern system is likely to have a variety of components that work together to protect your home. You’ll probably have motion sensors, which detect movement in specific areas; cameras, which can be used for surveillance or monitored by an operator; a smartphone app that allows you to arm and disarm the system remotely; and even video doorbells (sometimes called “door viewers”) that let you see who’s at the door from anywhere in the world on your phone or computer. 

These components can be added to the existing equipment saving money from purchasing an entire new system.

In many cases, you will be able to use the entry and motion sensors from the original system.  If they need replaced though, they are relatively inexpensive.  You may also want to update your security system’s hardware to make it more efficient. For example, if the keypad is old and unable to handle newer features, consider replacing it with a new one that does have those capabilities.


Monitoring is the process of having a security company remotely monitor your alarm. If there is an intrusion, they will alert you and/or law enforcement. You can also control the system yourself from your phone, tablet or computer through the app that comes with the system. I highly recommend this option as it is convenient and inexpensive; however, if you do not have a cell phone or internet access but still want monitoring services they do offer landline options as well.
