The HD security camera DVRs are hybrid CCTV DVRs that work with the following types of cameras: analog CCTV, AHD, and HD-TVI. Users may configure each channel for any of these camera types. For example, you may have an analog CCTV camera connected to channel one, a 720p AHD camera connected to channel two, a 1080p AHD camera connected to channel three, and a HD-TVI camera connected to channel four (720p and 1080p is also supported for HD-TVI cameras). These hybrid CCTV DVRs are the best choice for users that have existing standard definition CCTV cameras and want to upgrade to high definition surveillance cameras. They are also a great choice for customers that want a 100% HD surveillance system because all channels can also be configured for high definition cameras if you choose.

If you are looking for one of the best security DVRs on the market that offers remote camera viewing for every major computer and mobile platform including MAC, Windows, iPhone, iPad, and Android, then the iDVR-PRO is the right choice for you
