  1. Ok, it’s dark enough here to make a preliminary call on the nighttime image of the HVD. It’s pretty grainy and not as detailed as the 721, which produce an excellent nighttime image. The HVDs also thrashed a bit when switching from color to B&W modes. I’m starting think that this thrashing problem may be “normalâ€


  2. We're in Texas, USA

     

    Also, they have tossed a glass bottle of tomato sauce, and several chunks of meat.

     

    It shouldn't be hard to capture those items on video, even in Texas.

     

    From what you describe, it sounds like you'll need several cameras with telephoto lenses. A varifocal that goes up to 50mm should work fine. I’d start with two cameras and think about adding a third, if necessary zoom in to capture more detail.

     

    The problem, of course, will be lighting at night. Your best bet may be to install low voltage uplighting against the fence. That way you wouldn’t be disturbing your wonderful neighbor, but still be able to capture what is tossed over the fence with reasonable detail. The type of IR lighting you would need would be much more expensive and more difficult to get right, but that would be another option.


  3. also noticed this same behavior when my face or hand blocked the view when installing the dome.

    That would be the auto Iris and is normal. Cover your eyes with your hand...same concept.

     

    I'm referring to the activity of the mechanical IR cut filter and color-to-B&W switching, not the auto iris.


  4. Ok, installed the Nuvico HVDs today and the daytime images are excellent! They actually look sharper than the Samsung 721 images. I’ll comment on the night image after it gets dark. Meanwhile a few general comments:

     

    These are my first domes, so I can't comment on how they compare to others, but the camera, lens, and gimbal are plasticy and delicate-looking. In fact, the gimbal on one of the domes I received was loose from the base and the attached camera and lens was rattling around in the dome case during shipment. The dome casing itself appears pretty solid, once you get everything sealed up.

     

    There are 8 dip switches that allow you to set “flickerlessâ€


  5. Most important, do they have IR cut Filter, and do they switch to lower light BW or stay the same Lux Level ... let us know kays, we're depending on you

     

    You are so far testing hard to get items like Samsung Techwin, and now Nuvico ... so will be good to know whether it is worth the hassle of filling out those long dealer forms they wanted me to fill out .,.

     

    I feel the pressure ....

     

    Yep, dey gottem mechanical IR cut filters. Rory, I hear and record your advice and I wouldn't consider spending so much on a day/night camera without a mechanical IR cut filter.


  6. Fred have you tried the Nuvico/Vitek Day Night Dome yet?

     

    Was going to use a couple of them for this plumbing company if we gat the job. Will keep you posted.

     

    I've got two Nuvico day/night domes that I'll be installing over the weekend. So far. I've had a mixed reaction from the "bench test" (more like "couch test" around here).


  7. well i waited outside for 4 hours to be picked up, but just passed out, thought i was in a different world when i woke up, but no .... was just eating the pavement

     

    I hear it can take anywhere from 10 hours to a week before you get sucked into a worm hole. So you might want to give it another try and be more patient. It helps if you stand very still and position your hands open on top of your head as if you have moose antlers.


  8. are you trying to see in pitch dark?? Have you cleaned the lens face? Have you tried to focus it? Could be bad also, shiit happens. The ones I have tested are equal in quality to a High Res Box camera.

     

    The camera is not IR sensitive, so it can't be used at night.

     

    I've cleaned the inside and outside of the outer glass and lens. Yes, and focused.

     

    The image is much better in low light, but next to worthless in bright sunlight.
