But the video will be slow with this type of camera, using DSS (digital slow shutter). IR is better (once setup properly), but artificial lighting ofcourse is always best. The DSS feature is nice, have a camera here I tested that has it, but I cant take the slow video. BTW on many box cameras you can simply adjust the shutter manually to mimic the same thing. http://www.cctvforum.com/viewtopic.php?t=9946

^- What he said Other than that, here are some previous threads: http://www.cctvforum.com/viewtopic.php?t=9974&highlight=aventura http://www.cctvforum.com/viewtopic.php?t=2542&highlight=aventura http://www.cctvforum.com/viewtopic.php?t=482&highlight=aventura

Glad you got it straight. Seems not many on the forum are using them or had experience with them, but will be sure to try them sometime if I get a "chance"

Its called Windows 7 now.

Yeah I see that one too, has alot more IR though otherwise seems similar in quality, Color/IR instead of Day Night .. Ive used quite a few like that in the past, testing, but I never liked them enough to sell them. The monitor/TV would just be to test the camera quality, do any focusing required also. Most fixed lens cameras are already focused but in my experience sometimes not to the best they could be. Either way, typically when an installer receives the camera, they will test them directly to a monitor before connecting them to the DVR - to make sure the camera is working up to speed. Yep functionality the software has (for the price that is), Ive used it before, the client software is much better in that regard than the browser based though. But the quality is awful, always has been, I asked them about that a long time ago but seems they have not made it better yet. Like you mentioned, probably an issue on the DVRs server side, especially since it also appears in the client software. That monitor is probably very low quality, if it's like the cheap ones Ive seen in the past that came with the kits; I imagine a TV would be better. Should be RG59 for best quality. If its thin then its probably just RCA Cable, or maybe RG56-58; the all in one DIY cables ive used in the past were just RCA video and power, 25, 50, 75, 100' lengths with RCA on one end and a BNC adapter on the other. I dont think thats your problem in this case though, but it would be good to get the right cable just incase anything else comes up, such as interference. Basically the quality will get somewhat better once a decent camera is used, and perhaps the cable from the camera to the DVR. It will always be much lower over the LAN than direct at the DVR though. Example from the AvTech software: High Res OEM Camera Extreme CCTV Ex-80 Dual True Day/Night Long Range IR Camera: Now from a PC Based DVR over the network: Cheap OEM Low Res Color Bullet On a Stand Alone GE Kalatel DVR: Box True Day/Night Camera with separate UF500 Infrared: Now the EX82 Dual True Day/Night Long Range IR Camera: http://www.bahamassecurity.com/tmp/dn_1.jpg

is this the camera? http://detail.china.alibaba.com/buyer/offerdetail/77080073.html cant find a manufacturer called Mitar though.

Hi, there are a couple issues here. 1-The camera in question is just a Color/IR Camera - a True Day Night Camera would give a much better image. 2-The DVR in question is a budget Entry level DVR, its client software video is always low quality, in fact the quality is one of the worse I have seen from any DVR yet. BUT, for the price it is not bad - it is probably the cheapest DVR on the market. The quality at the DVR itself normally is very good though. You could use a video capture card (eg. Avermedia or other) inside a PC (or a USB Capture Cable for a laptop), run a cable from the monitor out on the DVR to the PC Capture card, then record that raw video on the PC (See thread in DVR Card forum on Generic Software, use something like AmCap, VidCap, or one that comes with the card). Basically you need to ignore what you see through the software, as that does not do the DVR or the Camera justice. You need to plug the camera direct into a CCTV CRT Monitor, or a CRT TV (eg. 13" TV) and check the camera with that. The image should be very good. You could also use one of those monitors/TV on the monitor out from the DVR and use that to view the video from the DVR; live and recorded. If you dont have either monitor or TV, you could use a VGA converter to a PC LCD Monitor (or use the RCA/AV in on an LCD that has it), however the image will be much lower quality - better than the quality you are seeing through the client software though.

965 Chipset .. used it before and it worked okay. No didnt get a chance.

Dont know how you got in their API and .. dont wanna know (on the forum at least ). I know about hooking but normally would need to know the app a little more indepth to know what to hook, and the commands? Anyway, actually most current DVR software needs alot more than that. For example, older versions of GeoVision use to run on 2Ghz but now it needs much faster CPU and alot more memory - I know as I use a 2.0Ghz AMD with 512MB Ram .. As to the Driver, to get the Bt878 driver to work for your card, you will probably need to do what I did for the GeoVision. Basically download and run BTSpy: http://btwincap.sourceforge.net/download.html To use BTSpy you would open up the DVR Card's program, enable all cameras and views, and watch some video. Then run BTSpy and it would create a custom text file to be used in the Bt878 Driver installer. Thats how I got it to work with a GeoVision card. Should be some directions with the BTspy program, I havent used it in a long time. DiVis is Chance-i, they are supposed to be good, though I have never used them. Have you tried to contact them yet regarding the problem? Also, I would try and get my hands on a hard wired camera to test, could be a problem with the video server. If you cant get a hardwired camera, try and plug the TV into it to test (video out on the TV using an RCA cable and an RCA-BNC Adapter to the DVR). Going by the specs though, it is more than likely the PC. See if you can try it on at least a 3.0Ghz Pentium 4 or similar AMD, though since most cards require the Intel Chipset, you may need to look for one of those. If it was a GeoVision, straight away I would have said first change to an Intel Chipset, then get back to us. Just the way it is with these cards. Rory

Which Intel Chipset was it?

Is that 512 the bandwidth the ISP told you, or is that tested from the DVR site? Also, is that the upload bandwidth or the download bandwidth, at the DVR site? If there is only say 128K upload, that would be typical to see the cameras dropping off here and there, especially with higher quality cameras, color cameras, or alot of cameras such as 16. Each camera is a separate connection, so because one drops off, doesn't mean all the others will.

I just had an issue with a GV250-2 channel in a new PC .. strange thing is it worked in my Via PC just fine .. or at least it seemed so. Live and Recorded video, it stutters, actually it movers flowingly for a few seconds, then it stops, then back again .. over and over like that. Im wondering if they are neglecting the slower cards now, like the GV250 and GV600 .. anyway, the client is waiting on a GV1120 anyway, I just stuck it in the PC to test. Could be a bad card too though, or not 100% inside the slot .. who knows. Just thought I would throw it out there. Will open it up and take another look tomorrow.

Hi, are you sure its not: 1-The FPS limit on the card - what model is it? 2-The wireless camera/receiver - did you test a camera plugged directly into the card? I dont know the card though so cant comment on its software.

HDD Failures arent really the DVR's problem though, that would typically be either faulty drives from the HDD manufacturer, or Power Problems (such as Brownouts, Spikes, etc) in your area. The power issues can be fixed by using an Automatic Voltage Regulator (or UPS with AVR) for every DVR. In this country I would not dream of hooking up a DVR, PC, etc, without an AVR. Rory

Many of the Chinese DVRs based on HikVision have Virtual Matrix also, no idea how good they are though, just saw them advertising it from a couple years back. Geo has something like it but its not really the same, its called the Multi Quad Card, meaning it gives you outputs to multiple monitors with I believe it is 3xQuad and 1x16 views. Tell you what, recon sends me a couple SLI's, Scorp sends me the PC for it, and I will see if I can add it into my software I actually have a dual VGA card installed here, but it just gives you a wider screen, which personally I dont like, so I use it for a single monitor only.

Can it be they are adjusting to Vista? JD Yep, thats what I figure, since some of the boards I used which use to work fine, the audio no longer works. With the most recent GB mobo, tried everything but would not work properly, in the end just disabled all together. Sound cards are cheap and the rest of it works great!

Server close, at least in my development, is when your network/internet is disconnected, or drops the connection. But basically GeoVision's idea of what it is: Server closed the connection.

I just used the GA-P35-DS3R and it worked well. Ive had problems with the last few Asus boards I used, which is why I wanted to try GB, but they all have the same problems now, the onboard Audio does not work in XP anymore.

Dont want to go on a website derailment, but looked at that site in question, good prices on budget OEM products, but this scares me: "..is the nation leading OEM Manufacturer of CCTV surveillance digital video recorders, cameras, and supplies." They are NOT a manufacturer. They buy OEM gear which comes from Asia where it is actually manufactured. The manufacturers sell the same exact equipment to other distributors. "With thousands of proven system operating worldwide.." Spell check. Anyway, dont let that effect your choice on whether to buy from them, once again cheap prices so that may be what you want. I have to mention the forum also has advertisers (banner ads at top and links at left) and there are also many other members on the forum who are dealers, such as the above member. I would personally go with a forum advertiser or member over an unknown, but thats me. At least with a forum member you are a little more guaranteed that they know the CCTV business.

Sounds cool .. also if you get a chance check out bblean .. its a shell replacement for explorer .. i created a custom installer for that for DVRs sometime back, just never used it out in the field yet, but tested on my PC it worked fine. http://bb4win.sourceforge.net/bblean/ And I agree, Nlite is more of a trial and error thing. Will have to check out that tinyXP thing at some point.

Yep, basically the same thing as Nlite.

Sounds good, you could have done 4GB though with 64 bit XP. Also was that DDR or DDR2-533/667/800 etc? (huge diff between 667 and 800 btw). Also its been mentioned on hardware sites that Intel's Core 2 Duos are faster than AMD's similar line up, though cant confirm myself as not used the new AMDs, but the new Core 2's are flying (2.67 at least). Also, TinyXP? Was that an Nlite or PE type version? Only thing I found online for TinyXP was Pirated XP ..

So a virtual Matrix? I see alot of DVRs have that now .. dont have the $$ for the video cards to test them myself. I do actually have 4x LCDs here though I use ATI Cards myself, I think SLI is nVidia? 128 feeds, what was the hardware, Core 2 Duo (3ghz) or Quad core? or other? How much RAM? No the Casinos here use a Las Vegas company .. cant remember the name off hand but they are governed by the las vegas groups. Plus I could just build it myself if you send me the cards and software I just built a DVR for a collegue here, the new Core 2 Duo 2.67 (there was an older model) with 2GB Dual channel DDR2-800, 3x500GB HDDs, ATI 1550 Video Card .. GigaByte Mobo with the P35 Chipset ... Sata DVD Writer .. Antec Server Case, multiple Antec Fans, 500 watt Antec PSU, Removable Air Filter, Customized Windows XP Setup .. anyway its the fastest PC ive used yet .. my XP Setup helps but in this case alot of it is the hardware .. the newer Core 2 and then the DDR2-800. Nothing overclocked ofcourse. CPU running at full 2666 speed and staying average just under 30 degrees even without AC in the room ... Mobo temp a little higher around 35 degrees. This is loaded with GeoVision 8.12, just using a Budget card right now until they buy the card they want .. but Geo flies unlike it normally does .. I couldnt believe the response from it on this system. Like I mentioned before though Geo really likes more memory, over CPU.

that would be a Composite to VGA converter. You can get them cheap or expensive, same quality typically. Its up to you, I use a viewsonic model here, works well, quality is nothing compared to a CRT but I save alot of space. The model I have also converts Cable TV to VGA so I can watch TV on my regular PC LCD.

Ive used the GE (Kalatel) in the past myself, as well as Samsung and a couple other brands I cant remember the names of right now. Most important is to get their high res versions, 500TVL or greater for color, 650-1000TVL for B/W.
