What kind of cabling do I need to run from a surveillance camera to the IZON DVR?
A Standard coaxial cable such as the one which runs in your home to connect with the cable company is highly recommended (RG59U). You need to connect BNC connectors on the DVR end and BNC or RCA connectors on the camera end depending on the camera type. Try to keep cable length under 300ft and avoid close proximity to fluorescent fixtures or other electrical devices that may cause interference. For longer distances, there are a variety of other solutions from RG56U to fiber.
