Problem solved - this appears to be capture configuration problem. You have to choose field for scanning - odd or even, or you get this bouncing if it's set to "any" field.

Nah, we're using local power supplies - every camera has 1A power supply (they use around 300-400 mA), we're using UTP for power and signal, and the power line lenght isn't greater than 10 m. on any camera (from power supply to camera). One of the power supplies is even 3A and the camera still bounces.

Hi, We have the following problem: I have two parking lots with 4 cameras total (2 entrances, 2 exits), on a single computer with a capture card based on Conexant BT878A chip. All the cameras are connected via baluns with local power supplies. The problem is that the image is moving slightly - the picture is perfect, there is no ghosting, ground loops, etc, but the image is literally "bouncing" a few pixels up and down every few seconds. The cameras are vandal proof domes installed on the barriers - they are not moving. I've encountered the problem many times before, mainly with Geovision cards, but it never bothered me until now. On these parking lots, though, it is critical, because I'm using the cameras for Licence Plate Recognition - we have developed our own parking solution complete with licence plate recognition, barrier automation, automatic payment terminals and so on. The software takes a capture of the image every 3 seconds after a trigger is used (inductive loop or button). If the capture is taken during a "bounce", though, the number is recognized incorrectly, the barrier doesn't open the my phones start ringing. If you park a car directly in front of the camera and start the recognition, every 4th or 5th attempt will be wrong because of the bouncing.

I've developed my own program with different integration modules - the general idea is to offer out-of-the-box solution to the customer - almost 80 % of current POS software works with our program without any further customizations. I'm not bound with Geovision either - there is no reason we shouldn't be able to integrate various different interfaces.

The price of GV-POS Text Sender is different in each country - depends on distributor. Last time I checked it was around 100 EURO per license (POS) POS Text Sender only works with generated TXT/INI/JNL files. If your POS system doesn't support generation of such files, you'll have to do it another way. Fortunately, we've developed an integration software, which works without any additional Geovision hardware or dongles, and allows several other ways to do it: a) Virtual printer creation + network sharing + parsing and formatting – it allows seamless integration with every POS system capable of printing receipts on Windows based printer - everything you print on a certain printer anywhere on the network is visualized in Geovision. b) Virtual COM port creation > RS232>TCP/IP>RS232 conversion and parsing – it allows creation and capturing of a virtual COM port for those programs that cannot print receipt copies to Windows based printers. The third option is to make SQL Database direct integration, but it is very specific and time-consuming.

You should go to Video Source menu and choose 720x576 Deinterlaced resolution. Afterwards you should change the recording quality, which is done individually for each camera.
