Upgrade existing wired home security system

If your alarm system is proprietary, your system is programmed to function correctly only as long as you continue paying the original company that sold it to you. For example, no other company can monitor a SimpliSafe, Cox, Brinks Home, or Xfinity Home system .

In most cases old equipment can be monitored to some degree , but there may be limitations, such as some features not being supported.

If your existing alarm security system is still in good condition, you can use it as is . For example, if you have an ADT system already installed you can sign up for their monitoring service. For some people, this option is a straightforward way to protect their homes.
