The drivers are one thing.. the software is another---too large for an email attachment .The drivers are proprietary to the software. The shortcomings I saw with it: 1. It turns the computer into a server--no big deal for a spare machine 2. It has to use a proprietary client software to view the cams remotely--better for system security so that someone couldn't use your cams to case your home or business but inconvenient if you wanted a generic web-browser view from any pc with any OS. 3. No SMS text or email of motion detection/intruder alert 4. No FTP upload so files could be stored remotely--if a theif breaks in they can steal the cam system and there goes the evidence possibly.

DKtucson, help me better understand what you mean. I do have the 4 chip 4 channel DVR card. 4 BNC inputs and can do 120fps = 30fps per channel. So, why would it be manufactured w/ 4 ports and the ability to record all 4 channels simultaneously at 30fps and actually not be able to? I am very confused. Or did you mean that the software (Active webcam) wouldn't work with my 4 chip 4 channel DVR card? I really think this is a driver issue. Is the driver I got from the Active webcam software just for a 1 chip, 1 channel DVR card? If so, how do I get my grubby little hands on a 4 chip, 4 channel DVR card driver(s)? Thanks! I too have the same card and have also been trying to find a generic driver that will drive all 4 ports. My card came with software called DVRnet that is *ok* but doesn't have quite the features I would prefer--but it is useable with all 4 cameras. If I recall from memory it loads NV800 drivers in device manager. I too have tried the BTwincap drivers and it appears to load successfully but all I get is one good output and the other 3 are blue "stand by" screens like no video. If I try to move one cam to each port one at a time the one same output still works and the other 3 are still blue . The driver that seems to get loaded is for the 1 chip 4 channel card (30fps divided by the 4 inputs or about 7fps per channel)

Have you tried using AMCAP(freeware) to see if the other 3 cameras will go? If you have the 4 chip 4 channel card (120fps or 30 fps per channel) my bet will be that they won't fly. All I have been able to get is 1 channel to go using the generic BT848/878 wincap drivers which is what comes with the active webcam software as well as from other sources. The single chip 4 channel cards are a breeze, they work fine but the 4 chip ones that I have will only work (so far) with the DVRnet software they came with and all 4 do work. On a plus note, I recently got some 4 chip Phillips cards from geeks dot com and wave-p software works for those--I luckily stumbled onto that.

kocur, Thanks for the tip but that didn't do it....the active webcam has the same BTwincap driver that won't auto detect the card . Just to try , I uninstalled the drivers I had, fired up the py-soft active webcam trial--it suggested that I should install the btwincap drivers for the 878a and launched the same BTwincap driver program I've been using. No auto detect--no easy install. The single-chip 4 channel cards are a breeze--not these 4 chip 4 channel cards

I tried BTspy when I was running the dvrnet software it came bundled with--no go on the detection and importing the text file. I guess it didn't see the cam as "actively selected". You'd think with all the outlets blowing these out someone would have been down this road before. the dig-dvrnet software isn't bad but I'd rather have choices especially for a non-techie end user

I too have one of these 4 chip cards...what profile in the BTwincap driver did you use to get it to fly?

Hello folks, I have been tinkering with various cards with different levels of success. For a brief recap I put together a dvr for a friend of mine that owns a gunshop--works great with the pico2000 it came with. Now to more modern times: The 1 chip cards that split the cams to 4 inputs--no problems with the BTwincap driver available from sourceforge. I can then use generic non-pirated software that's not proprietary. The problem seems to be when I go to the nicer 4 chip cards--they will load image on the first camera and black outputs on the rest. I have also had the same thing happen with the Phillips saa7170 wdm driver. 1 camera works and black on the rest. If I use the proprietary drivers and the bootleg software they work but then have other issues like I don't care for the interface or the need for client software to view remotely etc. One issue I had with the phillips drivers in a kodicom clone is that it loaded 4 capture drives and 4 tuner drivers (no tv on this card) On the BTTV driver N800 clone is that it loaded 4 each of video and audio but had 1 audio input--just weird stuff. Any input on my output? I see a previous post referencing a btinstall.dll file from argus fixing this...but no file link and no details
