It is a completly new model. It no longer has the JPEG option.

It is MPEG recording, and MPEG over the internet.

Video Viewer can connect to the older DVRs. Video Server E cannot connect to the newer DVR.

You can download Video Viewer here:

Is there anything that you need from me to help you with the new model?

Thanks!

I've read this thread many times, but hadn't gotten around to playing with the app until today. I have a Lorex 16ch DVR (model: DXR216). The "driver" disk (not a driver, but app) is titled PCD-732E and comes with Video Server E (v1.0.6.6). That gave me a hint about the true background of the DVR. I now know it's an AVTECH OEM'd device.

Unfortunately, I can't find any info on the web about it. I've owned it (brand new) for about 2 months. I've called Lorex, but the support folks didn't even know that I could go to the AVTech site and get stuff that would work with this DVR - go figure.

Anyway, after debugging Steve's app for a while (some variables were inititalized improperly), I've gotten as far as the InitSerialCmd function. When the app starts, it gives my DVR a "777W" ID, then the b_V732E flag = True. After that, it thinks that it's an n_Device=5, which is a "9CH DMR."

Based on everything I've read, I think this Lorex device is actually an AVC760 jpeg (thus the 732E disk that came with it.)

Anyone know anything about it? Am I just wasting my time trying to get this app to work on it? It just seems so close, yet so far.

Thanks in advance!

Thanks scorpion. I looked through your site, and read some of the documents, but didn't find much that would help me identify my DVR. However, in doing more web searches, I did run into a manual for this device at the following site (can't post URLs yet): lorexstore (dot) lorextechnology (dot) com (slash) pdfs (slash) DXR216_MANUAL_EN.pdf.

It's really worthless though since everything in it refers to Video Server S, when this DVR only works with Video Server E. I did confirm though that it uses both JPEG and MPEG, so I continue to believe that it was based on the AVC760. It's possible the Steve's app doesn't work because of the dual compression format support.

I'll continue with my search, but if you can think of something else, please let me know.

Thanks again..

Your DVR is an AVTech DVR model number AVC 777. If it has an internet connection then it would be the AVC 777W.

I am surprised that you did not see your DVR on this page:

http://scorpiontheater.com/cpcamtechsupport.aspx

When this DVR first came out it did in fact use Video Server S.

AVTech came out with a model of DVRs at the time, and the newer DVRs used Video Server E.

AT that very moment in time they changed some of the chips on the board, and then updated the AVC 777, and the AVC776 to use Video Server E.

It was kind of confusing at the time for some dealers as you might get some of the stock that they were trying to deplete of the Video Server S models, or you might get a Video Server E model.

If your DVR does in fact use Video Server E, then you might be able to use Video Viewer.

http://scorpiontheater.com/videoviewer.aspx

I am surprised that Steve's AP did not work with your DVR if it does use Video Server E. Then again it may not surprise me as it may have a different chip set on the PC board compared to the AVC 760 style boards.

If you can use Video Server E then it should take Steve's AP. I just do not know why it would not.

I would not worry about the 9CH DMR(AVC 776) as the two DVRs are kissing cousins. They are identical machines except for 9 verses 16 channels. Everything else is exactly the same. Same menu, same functions, ect.

Now you are up to date! What do you think?

My app is the java applet from the web page with an application wrapped around it to provide the buttons etc. It's not based on Video Server E, and it is entirely possible that Video Server E has broader support. That makes sense as the applet on which my application is based would normally only be run for my specific machine, and so should only be expected to support it, whereas Video Server E would need broader compatibility.

Thanks for helping me figure this out! I now have a much broader set of options. It turns out that I didn't read all the 16ch documents that you had on your site and didn't get to this particular one. It does have internet connection, btw.

I tried video viewer, but it doesn't seem to work. I get a "login failed" error. Because of all the changes you mention, I wouldn't be surprised if AVTECH did some specific change at the request of Lorex.

This means that Steve's app is recognizing the DVR at initialization, but gets confused later. It may be because of the number of the channels. I have yet to figure out all the details, but I'm working on it. It helps to know what I'm working with :)

Steve, yes, I am aware of this, but technically it should work with all the DVRs you listed earlier. Mine is on that list.

Just for kicks, I extracted the java app from my machine, and decompiled it. It turns out that, aside from some parameters and function name differences, the main app is very similar to yours. AVTech seems to use the same app for all of its java-based DVRs.

BTW, Video Server E is just a UI wrapper for the java apps stored on the DVR.

Knowing very little about Java (nothing before a couple of days ago), I wanted to leverage what you had done. My ultimate goal is get this to run on my Windows Mobile phone as a Midlet. Of course, this is just for fun, so I'm digging into it as I get free time.

Thanks for getting me closer to this goal!

Have you tried Eagle Eye (old version) on your phone?

Any chance the source is available ? I'd be interested in extending it for my 16 channel DVR.

Thanks

scorpion,

I've tried all the applets from that site. Here are my results:

* EagleEyes (J2ME) gives me a blank screen after I create a login profile and click on it. No error message, no anything.
* EagleEyes (J2ME New version) says: "java.lang.NoClassDefFoundError" when starting it up
* EagleEyes (For WinCE) gives "The network is failed!!" upon trying to connect to the DVR
* EagleEyes (For WinCE New Version) gives "Login Failed!" upon trying to connect to the DVR
* Supervisor (aka GPRS/3G software) doesn't install for security reasons. It says "permission javax.microedition.io.Connector.socket is not available on this device"

I got a hold of the source code for EagleEyes (by decompiling it.) It looks like it's only for IP cameras. All device references in the code are for "IPCamObject." However, it also seems to use 16 small icons. I presume it's to reference channels 1-16 on the UI. Are you sure this is supposed to work with a DVR? If so, I can try debugging it.

Steve's code is supposed to work on 16 channel systems also. He's got a pointer to the source in one of his earlier replies. check it out. However, since it doesn't work on my 16ch 777w, I'm trying to figure out why. Which model do you have? If you can figure it out before I do, let me know.

I have downloaded your java app and I ran it in Ubuntu 9.04 64 bit.
I must say that it starts very fast but the problem is that my cpu load is very high and for a laptop is that a bad thing. ;)

That's what I had to say. :)

CPU Intel P8400 @ 2.26 GHz
4 Gig Ram

The software works with Video Server E.

Does your 777W use Video Server S?

If you are using Video Server S then Steve's AP will not work with your 777W.

If your 777 uses Video Server E, then Steve's AP should work.

It also might be that you do not have the chipset that the AVC 785, and 787 uses?

Video Server E runs fine as-is in Ubuntu using the Wine Windows emulator.
