Investigated further 6204U only seems to over recording at upto 720x288.

 

So not ideal

 

How about - 760A Real Time 4 CH Digital Video Recorder?

When you ask about a particular DVR, you'll want to tell us what

brand it is in addition to the model so there's no confusion.

Doesn't appear to be badged up as a particular brand!

 

I'm guessing its based on or is a unbadged Avtech

Alternatively what about the 4 channel version of this DVR

Specifically I'm concerned about the quality of playback from a recording with regards to the compression. As whilst they both offer resonable resolution, if the compression is poor so will the recorded image.

 

Do these offer a decent picture in playback compared to similar priced DVRs?

Hey there.

 

I'm no expert, in fact a novice like yourself, however, I've just purchased a DVR and so had to do some research in the meanwhile - so I've got a couple of tips for you in a nutshell...

 

The first thing I tried to understand, were what all these recording modes were all about. i.e. D1, CIF, Half CIF etc... D1 is 720x576- and the rest are lower resolutions - so in essence, I tried to find a recorder that was at least able to record in that mode.

 

MPEG4/H.264 is the latest compression codec in widespread usage that offers the best compression/picture quality thus far.

 

The other thing to look at is the IPS of the unit. They usually give that as a total, i.e. for a four channel system it might be 100IPS (on a PAL system), which means 25 IPS (images per second?) per channel.

 

So ideally, a system that's MPEG4, records in D1, and at least at 25IPS should be a good basis as a benchmark.

 

It's hard to find those features on one unit on a budget. My budget was around (£500/$700USD).

 

I've finally plumped for a unit that records at D1, but only in one channel mode. In 4 channel mode it drops to CIF (360x288) - so I guess you need to query the suppliers of the units you're interested in - to see if those units record 4 channels simultaneously in D1, or if that only happens in 1 channel (full screen) mode.

 

Hope that helps.

 

ps. my other posts show the units I was considering, and the one I went for.
