Volume, volume, volume.
Your regular TV DVR is designed to record at most five or six things, while a security DVR could record 24 or more camera feeds at the same time. On the other hand, a security DVR is not designed to decode the feeds from your cable or satellite company. They really are two different things even though they have the same name.
If you need a security or surveillance system, Solid Signal has a wide variety of security DVRs
in many different price ranges designed to meet whatever your need is, whether it's simple office surveillance or something really complex with multiple cameras, motion detection and the ability to alert your smartphone to what's going on.
If you need a complete system, you might want to consider the pre-packaged kits
we have available as well. Whether you just need something like a babycam or something capable of watching your whole warehouse, we have the parts and accessories you need!
