A digital security system is any system that integrates digital data for the purpose of creating, sending, or recording information that can be used to protect something. That’s a pretty broad definition, but then again digital security system is a pretty broad phrase.
Since most security alarm systems primarily deal with on/off states (door open/door closed) we could consider them to be inherently digital, but that’s not really what we mean here. What we mean by digital security system is a video security system that operates on the basis of digital data transfer as opposed to an analog system.
If you’re looking for no-hassle security alarms that are easy to install and operate, try using wire free security alarm systems. These security alarm systems detect and notify just like their “wired” counterparts, however the sensors used in these systems do not require a communication wire installed from each sensor to the control panel.
