4 CH USB 2.0 DVR PC Digital Audio Video Security Camera Surveillance Recorder

This is not a cheesy DVR. Construction and materials look and feel top notch. I set up a small camera system for my home, (3 cameras). I had no problems getting the software to work with windows 7. When I plugged in the USB connector, at first my computer did not recognize the devise, it said "unknown devise" or something to that effect. After restarting and plugging it back in, then my computer saw the devise as "QQDVR" and windows installed the drivers for me. I tried other DVRs in the past, like the one from Sharx Security that installs into a PCI slot and had to return it because it was not compatible with Windows 7. This one works great with windows 7. Other great features include 4 channels video with their own audio jacks, so 4 channels audio/video (4 BNC Video jacks,4 Audio RCA jacks). Frame rates are great even with all three cameras running. Cameras are independently fully adjustable. Setting up the remote surveillance feature was easy and I was able to monitor my property as well as motion record while I was on vacation 1100mi away from home. I was able to monitor from my laptop at the hotel I was staying in. This DVR takes up no space in my computer case allowing my computer to run cooler because there is no warm/hot, air blocking PCI card in my PCI slot. This would also be a great product for someone who wants to use it with their laptop. Note: When you configure the software, you will be asked what signal type your cameras are, your choices are "PAL" and "NTSC", if you are in the United States choose "NTSC". Don't select "PAL" I did this by mistake and I had no signal. Also, if you put your computer into "sleep mode", that will disable the DVR software temporarily until you do a restart and open the program again. When I record, I disable my "sleep" function. If you get confused installing the QQDVR, someone posted a video on YouTube explaining the install.

The Product's drivers and software were fairly simple to to install and after hooking up the CCTV cameras and rebooting the computer it was easy to configure the video settings for each camera. The video was almost as good as it was on my Television sets. But the audio was scratchy and very week even with the input gain maxed out and the speaker volume on my PC maxed out. The microphones and wiring are good because when plugged into the TV's the audio is very clear with volume controls adjusted at low and loud and clear with the volume adjusted half way. The video is better than I expected but the audio is poor.

I have tried to install this on 3 different laptops (Dell, HP and ACer) ranging with Windows XP to 7....all USB 2.0 ports and a desktop Vista OS..no luck. The CD that supposedly has the drivers and programs on it - I just can't explain it. When you open the disc and you view the main folder, it shows the user manual, FAQs, etc...plus some other programs. The one I'm concerned with is the all important program that makes it do what it is supposed to do. However, when I try to run those app files, it says file/path unknown! Yet when you look at the folder properties and file properties, it clearly states there are KBs of information there. So it's there but not there?! I tried Google and the most viable answer was to swap out one of their original files for a different one which others have took their time to locate! It seems like you would have to be somewhat of a programmer to make THEIR product work. WHAT?! The user manuals are not too helpful and I found a broken English filled youtube instructional that made it work instantly...IN CHINA. Bad news for me here in the USA.I tried to plug and play it, boot the comp while it was plugged, boot while DVR and security cams were already feeding signals..etc etc. No luck. Unless someone has a miracle solution where I'm not reprogramming their software for them, I am returning it as soon as I test out the accompanying item to save me an extra trip to the post office. Any resolutions please, I'll be fair and try if it works. Complete and utter outsourced crap so far...BTW: I came across a site that sells these things bulk, the price per unit was more like 14 bucks ea and they can churn these things out at 1000 units per week. SMH

a little advice to those who don't want to struggle with this card. first, the drivers it shipped with don't work (or didn't for me). as in i could never get video to display at all. i tried all sorts of variables with operating systems and hardware ... but always the same result. no video displayed on screen . if you go to ebay and find the vendor who is selling this, there is a link to download the qqdvr software on the product description page. this will do the trick. when you install, be sure to select the ntsc option rather than the pal option.i wasted a ton of time trying to get this thing to work until i blundered into this solution online. i went to ebay, found the software, and now every computer that i leave up 24/7 (there are three of them) has 4 cameras attached. the beauty of this vs. a dedicated dvr is that you can, for instance, transfer/backup files across you network, or (as i do), run mirrored drives.if you step onto my property, i've got it on video. and you could beat all the computer equipment i have to a pulp, because i have it backed up in a very secure location... you would never find the backup. you could burn every building i have down, and you'd still never find it. this is a feature i really like.for the money, this solution is simply unbeatable.

Well, I thought this was going to work, but I keep having problems getting more than one camera to work at a time, and the program could be more user friendly. I can't get it to minimize and then come back to full screen, which means I can't use my computer for anything else once I launch the program. I've been working with computers since 1980, and have used DVR security devices for over 10 years, but all I can say is that you get what you pay for. If anyone else has had experience with this USB DVR device, I would love to hear from you.
