Thanks rory, Yep I'll assume it's a typo, since they specified lan in the description. Cheers Duncan

MJPEG is just a collection of JPEG images combined into a single file. This means that frame captures look good (jpegs were designed for static images), but compression suffers as it cannot compress across frames. MJPEG does compress across frames, but is meant to be viewed in motion, so stills don't look quite so crisp. Settings can sometimes be tweaked so it's not quite so black and white as this, but that's the general theory. "MJPEG is an outdated and inefficient codec, whose main advantages are low processor overhead, ease of editing, ease of implementation by developers using existing JPEG algorithms or libraries, and broad compatibility." http://en.wikipedia.org/wiki/Mjpeg Duncan

I have found a Kalatel on an auction site, listed as: KALATEL CALIBER DVMR-4CT LAN BASED RECORDER Will this be triplex and talk to WaveReader over the lan like my 16CT or is it possibly an earlier model with lower specs? Duncan

A TCP/IP port capture should be completely transparent from the client side. Could take you a while to add code to pull all the relevant info from the data stream though. Shouldn't be any technical issues though. http://www.wireshark.org/ is very useful for analysing network comms. Duncan

Sorry about that! Bummer, and I still can't post links, will try again later if anyone's interested... Duncan (p.s. Looking for an SDK for a GE DVMRe if anyone can help. Not for commercial use, just want to write some software for a unit I picked up cheap and have running at my factory.)

Jobs so far have been to order, so we don't have a flyer or a demo up yet. I'll see if I can get the sales guys to put one up. Really just posting my experience in case I can help others with any questions / issues that I may have already dealt with. Here are some links for you though: Duncan (p.s.

We have done a few jobs in this area. Only small ones so far (bars etc) with 16-32 cameras. Have used both serial capture on till receipts (on old non-ethernet tills), and database integration on some ethernet tills. Database integration obviously gives far more information, and gives many more searchable fields. All our projects so far are on Panasonic DVRs. We have gained Panasonic preferred partner status here in New Zealand, and Panasonic has been quite helpful in pushing our product here. The Quest tills used in our latest projects are based on custom micro boards, and report their data back to the office PC where it is stored in an Access database. We do a decent amount of supermarket work in our day-to-day business and have been looking at trying to get a foot in the door there, but with limited success so far. Duncan

Rory, Do you have an SDK for the DVRMe? Looking to get video playback/searching into a custom app on my PC. Duncan
