HD-over-Coax DVRs work with HD-AVS and HD-SDI systems. They record and store high definition footage from surveillance cameras over a coaxial cable such as RG59. The video quality of HD-over-Coax rivals that of IP systems without costing quite as much. We offer systems that have resolutions between 720p and 1080p. Each DVR has plenty of storage space and users can monitor footage remotely from a PC or mobile device. We offer DVRs that are compatible with up to 32 different surveillance cameras. High resolution video is becoming more and more in demand as users are realizing that clear footage can be beneficial in identifying criminals, license plate numbers and potential threats. Also, it is often easier for users to upgrade their existing analog CCTV systems to HD-over-Coax because they use the same cables and set up.
