A definition of frames-per-second (FPS)
FPS is a term that describes the processing speed of a series of still image frames. More specifically, for example, 15 FPS means that a processor can record a series of 15 still image frames in one second so that when the frames are played back for a viewer, in one second of time, the viewer sees all 15 frames in the sequence in which they were recorded, giving it the appearance of motion.

Although the cable used for digital video security systems does not carry a high voltage charge, coax surge protection is still required to protect your system from lightening and even overzealous power outages, and power surges. If a surge makes its way to the camera or to the DVR your system could be destroyed.
While power outages and other non-lightening power surges are highly irregular for digital video security camera systems, coax surge protection is needed much more often, especially if you have outdoor cameras that could be a target for a random lightening bolt hit.

One of the benefits of selecting our DVRs are the various video outputs available. The biggest advantage is the HDMI video output. This output allows you to connect the DVR to an HD television or monitor using the HDMI input. This provides great detail since HD video is higher resolution than standard VGA. Additionally, some televisions only have RCA and HDMI inputs and this means that for most DVRs, you would need to convert from BNC to connect. With the Elite and Ultimate DVR you can connect directly just using an HDMI cable.
The next option on all of our DVRs is VGA. The VGA output will allow you to connect the DVR to a standard LCD monitor. Next, there is a BNC output which you can use to connect to a security monitor or the RCA input of a standard TV. Lastly, is the spot monitor output. The spot monitor uses BNC which can connect to a security monitor or a standard RCA input of a TV. The Elite and ultimate DVRs have a built in Matrix which allows you to have a separate sequence of cameras displayed on the spot monitor. This can be a very useful feature.
On the Elite and Ultimate DVRs there are also loop outs for every channel. The loop outs use BNC for the video outputs and are a convenient way to connect individual cameras to spot monitors that will display only one camera.
Unlike most DVRs, all the video outputs can be used at the same time. So essentially, you can have 3 main monitors, 1 Matrix spot monitor and then 1 spot monitor for each channel of the DVR.
