    Yea, the cards are limited to 720x480 D1 resolution (NTSC system). But you can certainly go buy an IP camera (megapixel if wanted), that will put out resolutions at 1080p and beyond!

     

    Holy moly. You mean the user manual was correct?

     

    That's lame as a cucumber in the sun.

     

    Anyone have any ideas when the Geovision cards will be able to handle the resolutions that the camera's are putting out?

     

    I still notice that Geovision only lists a 1024x768 window mode. Is that seriously still in place, meaning, if I have a widescreen monitor, the Geovision app only runs in 1024x768 after all this time?

     

    Holy Moly.

     

    IP cameras have nothing to do with analog capture cards. only that IP camera recording software (nvr) is sometimes bundled with software that comes with capture cards, like avermedia's cards

    What part is actually made in North America?

     

    Just wondering?

     

    They might be assembled in Canada but that would be it. The Chipsets, imagers, lens, all come from over seas.

    The key point might be where over seas. I don't have a problem with Japanese or Korean products. Only China and other 3rd world countries.

     

    The part that sets Avigilon apart from others is the Software. That's not coming from over seas.

    I wouldn't worry about a high res analog camera seeming overkill. Focus on the quality of the sample images you see posted here. I had everything from cheap $39 cameras all the way up to a 4mp IP camera on mine. With each step up in camera quality, the picture quality showed improvement. Don't go cheap and expect too much.

    if a $20 amazon camera can do it, hopefully the arecont can - both with some mods

     

    testing $20 color IR camera - hand over top of leds

    basically the IR cant be that powerful, just enough to pickup the plates at a certain distance, not to see anything else. Eg. See how the plates are picked up although too far from the camera, but that would be enough light to get the plates and nothing else at that distance, if the lens could zoom in that far.

    Thanks Rory. I can't tell if the headlights are on in these pictures. Basically, in my case, the picture washes out in the night with the Arecont 5100DN without an IR. I am going to try it next with your suggestion of using a low intensity IR (keep going up in intensity, if needed). If this setup doesn't work then I will use an analog camera (like you) for night time use and keep the Arecont for daytime. I picked up this Arecont camera (brand new) from Ebay for $150 and the 50 mm Fujinon lens for another $25 so I can easily afford to use two cameras for this purpose.

     

    Cheers.

     

    It's been my experience (both megapixel and analog) in order to capture plates at night, you need to set the shutter speed extreamly fast. Min 1/60-1/120. Its the only way to rid enough motion blur on moving vehicles to read plates. Problem is, that high of shutter speed lets in very little light. Hence the need for lots of IR. This will bounce off the reflective plates but plates will be about the only thing in the picture you'll see. This is why you generally have 2 cameras for LPR setups. 1 plate cam (high speed shutter) and 1 overview (normal speed shutter).

    Anyone have any experience with this:

    3.5" LCD, multimeter, cat5 tester, ptz controller, ptz data analyzer, video signal generator, even 1amp 12vdc power output for temporarily powering camera... pretty slick looking

     

    Also a bit cheaper than Rapport or Ideal. Like most things in the CCTV world, it's been re-branded a dozen times so if you've bought one I'd be interested what you gave for it.
