There are two types of Digital Video recorders used for CCTV system applications. There is the single channel device capable of recording a single video signal, which is similar in function to the conventional VHS VCR.

Secondly there is the digital recorder combined with a multiplexer, which can record a number of cameras, one after the other in rapid succession. VHS VCR and Multiplxers are now classed as old technology and is surpassed by the market leading Avermedia Range of DVRs.

MAS are Main Distributors for the market leading AverMedia Range of DVRs which incorporate the latest hybrid technology - they can record analogue, IP cameras and other remote DVR's.

Is it possible to operate the DMR range of digital recorders remotely?

Yes, it is possible to operate the DMR range of digital recorders remotely. This is achievable in two ways;

1) By using a RS232 connection to a PC you can remotely operate the functions of the DMR using the ASCCII code software package (see downloads). Please note this does not allow you to remotely view images from the unit.

2) By adding a simple network device (DMRNET) to the DMR range, live or pre-recorded images can be viewed from any PC connected to the same LAN, or via the internet from any location in the world. It also gives you full control.

How do I transfer information from a DVR to a tape?

As long as your DVR features a composite monitor output for playback then all you need to do is loop the video through the VCR, for example Monitor Output to VCR IN, VCR OUT to Monitor IN. Whatever you view on the system you can now record on the VCR. If you're using a domestic VCR you may require a scart to BNC cable.
