prophetkb 0 Posted October 25, 2013 Hello everyone, I recently came across some cameras and I'd like to find out if they are functioning so I can either use or sell them. If they are functioning, I'd like to setup a small home security system. I have an extra computer that came with, what my research has turned up, to be a dvr card . A Techwell TW2804 I believe. Some of the issues I've been having include: -Finding out if the card is meant to be run under Windows XP or Linux -Finding said card's driver. -Properly identifying the variety of cameras -Powering the cameras -Connecting the cameras to the PC DVR -Finding out if the iPIMS DVR software is compatible with these cameras I hope I can this forum can supply me with the assistance I am looking for so I can continue to educate myself in this interesting field and to help secure my home. I'll post some pictures of the cameras that I have once I get home. I hope you guys can assist me! These are the cameras I have. I have more than just one of each.

prophetkb 0 Posted October 25, 2013 Also, I believe this is a Techwell TW-2804 based on what I see and what I have researched, though, I could be wrong. Could someone verify for me? Share this post Link to post Share on other sites
beer30 0 Posted November 17, 2013 I just picked one up from our local computer graveyard a couple weeks back. I've been toying around with it, but cannot seem to get it to work in Ubuntu - I can see the device in the OS, but I will be damned if I can find a suitable driver. from an lspci -v: 04:00.0 Multimedia controller [0480]: Philips Semiconductors SAA7146 [1131:7146] (rev 01) Subsystem: Device [434c:4343] Flags: bus master, medium devsel, latency 64, IRQ 11 Memory at fe2ff000 (32-bit, non-prefetchable) I don't have a windows machine to play with right now, but I did find this and I believe that it might be just what you are looking for (drivers, install directions for Windoze): https://divisdvr.com/products/dvr-board/livcap/120n16.html Beer30 Share this post Link to post Share on other sites
prophetkb 0 Posted November 18, 2013 Thanks, I've been poking around with it for the past few weeks on both Windows XP and Ubuntu Desktop 12.04 with not luck on either. This card has caused me so much stress, I'm just going to sell it on Ebay along with the rest of my cameras AS IS and hope to make a little cash for it. Not to mention, only 2 people on this entire forum have been helpful. You, beer30, and some other guy a few weeks back. I can't find his name to give him credit.

beer30 0 Posted November 24, 2013 Unless the card is defective, I don't think it's the Techwell chips that are the problem, but the A-Logic chip. I've emailed the manufacturer asking about drivers (Windows and/or Linux). http://www.alogics.com/eng/_html/it/products_3.asp Prophetkb - can you confirm that the A-Logics chip is an AM-7116? It's hard to see the model from your picture. Does the larger chip have anything written on it? In a different post, PCXDream stated that the windows device manager said the following for his card that was like yours. PCI\VEN_1131&DEV_7146&SUBSYS_4343434C&REV_01 PCI\VEN_1131&DEV_7146&SUBSYS_4343434C PCI\VEN_1131&DEV_7146&CC_048000 PCI\VEN_1131&DEV_7146&CC_0480 This part: PCI\VEN_1131&DEV_7146 identifies a component as Phillips SAA7146 based. The subsystem part: 4343:434C is an unknown PCI device from all the Googling I've done. I cannot confirm the vendor id belongs to A-Logics, but cannot think of what else it would be. This is the windows equivalent to what I'm seeing on the Linux side. If I get a response from A-Logics, I'll post back and/or upload the drivers somewhere.

beer30 0 Posted November 24, 2013 Prophetkb - if you have not gotten rid of that card yet - I think I found the driver for Windows. In a previous post - only sent the link to the product. It does not look like the newest driver pack that they ship comes with the driver for this board, but the last driver pack does. The product description page says that it will only work with 32-bit Windows (XP through 7). https://divisdvr.com/products/dvr-board/livcap/120n16.html The drivers page - https://divisdvr.com/download/software.html Browse to Version 12.12.0 The first link for downloads is to the Drivers Package: https://divisdvr.com/download/software/12_12_0/Driver_v12.12.0.zip The contents of one of the .inf files located in the zip under /Driver_v.12.12.9/32/Ldrv File: DVRW2k.INF shows this: [Mfg] %String2% = DivisCTP.Device, PCI\VEN_1131&DEV_7146&SUBSYS_43434341 %String3% = DivisCTP.Device, PCI\VEN_1131&DEV_7146&SUBSYS_43434342 %String4% = DivisCTP.Device, PCI\VEN_1131&DEV_7146&SUBSYS_43434343 %String5% = DivisCTP.Device, PCI\VEN_1131&DEV_7146&SUBSYS_43434344 %String6% = DivisCTP.Device, PCI\VEN_1131&DEV_7146&SUBSYS_43434345 %String7% = DivisCTP.Device, PCI\VEN_1131&DEV_7146&SUBSYS_43434346 %String8% = DivisCTP.Device, PCI\VEN_1131&DEV_7146&SUBSYS_43434347 %String9% = DivisCTP.Device, PCI\VEN_1131&DEV_7146&SUBSYS_43434348 %String10% = DivisCTP.Device, PCI\VEN_1131&DEV_7146&SUBSYS_43434349 %String11% = DivisCTP.Device, PCI\VEN_1131&DEV_7146&SUBSYS_4343434B %String12% = DivisCTP.Device, PCI\VEN_1131&DEV_7146&SUBSYS_4343434C %String12% = DivisCTP.Device, PCI\VEN_1131&DEV_7146&SUBSYS_4343434D %String13% = DivisCTP.Device, PCI\VEN_1131&DEV_7146&SUBSYS_4343434E %String14% = DivisCTP.Device, PCI\VEN_1131&DEV_7146&SUBSYS_4343434F %String14% = DivisCTP.Device, PCI\VEN_1131&DEV_7146&SUBSYS_43434350 %String15% = DivisCTP.Device, PCI\VEN_1131&DEV_7146&SUBSYS_43434351 %String16% = DivisCTP.Device, PCI\VEN_1131&DEV_7146&SUBSYS_43434352 I don't have a 32bit Windows machine to test this out, but I would think it would work. I find it doubtful that I am going to get it working on 64 bit Ubuntu and am going to deinstall the card until a 32bit version of Windows comes into my life. I did not see anything in the 64 bit driver INF files for this combo... Beer30 Share this post Link to post Share on other sites
