Is the SDK for my DVR a myth?

[dvrdeviant 0]

Hi.

 

A while ago I bought my first dedicated DVR. I'd used the cameras I had connected to a 4 channel card in my PC, but didn't like leaving the PC on 24x7 for recording. I bought the device from eBay, and I've actually been quite happy with it. It was advertised as having an SDK, although that wasn't particularly why I got this model.

 

It's an 8 channel, pretty generic looking H.264 DVR. As I'm sure forum people here will know, if you search common terms like DVR H.264, you can find thousands of sellers, mostly originating in the far east (China, Taiwan etc). They all have the same generic photos on their websites, so it's pretty hard to determine who is actually manufacturing/developing these boxes, and who is just reselling them.

 

I was interested in the SDK side of things because I do software development for a living (but not anything like this field). My device came with a CD but that doesn't include anything that constitutes a software development kit. What it did come with is an ocx control(s) for use in Internet Explorer called NetSurveillance.ocx. This works OK(ish) but on modern OSes like Vista, you have to run IE with Admin privileges or it just craps out. There is also a copy of the "Mobile Eye" app for smartphones on the CD. This seems to be a quite well reviewed generic viewer for DVRs. Somewhere I read that it "should work with any of the DVRs from the far east" or something like that, re-inforcing the idea that I have a generic device.

 

Whilst trying to find out more about the device and the SDK, I found the firmware version listed as "V2.62.R07". Doing a search on that, I found this page

 

http://www.everpro.biz/down/class/

 

Where you could download that firmware (for free). They class that as firmware for their DVR602-8 device, which is an 8 channel DVR. Does anybody recognise this outfit as a real vendor, or just a reseller? Presumably whoever created the "Mobile Eye" app is either a master of reverse engineering or had access to an SDK (or detailed specs and protocol info).

 

I'd really like to be able to view the video feed from a linux desktop, either through a browser or in a standalone app. I'd be quite happy to write (and share) such an app if the necessary SDK was available. Does anybody have any pointers?

 

Thanks

thats why I like Dahua DVRs, can get the SDK right from their site, they also have a Linux and Mac software.

 

Anyway, going by the site you posted that seems to be a distributor not a manufacturer.

They have alibaba on their page and Ive yet to see a real manufacturer with that link, plus never heard of them.

It is a myth

Not quite a myth. At the risk of resurrecting a dead thread, here is a link to the SDK for this DVR and most other generic far east DVRs.

Very helpful, thanks.

 

Does anyone know the telnet password for the linux shell on these boxes?

BTW- if anyone did get around top writing a linux interface to this device, and can share that info, that would be fantastic..

Hello, We are trying to get video images from the h.264 generic DVR through the SDK, it is connecting on port 83, but gives blank images, any ideas why? should we be using a different port or so? thank you.
