    Cameras and NVR updated to 11/30/16 update:

    To some, adjusting the shutter speed is very important. From what I can find, there is no way to adjust it from the NVR. Supposedly you can adjust it by going into the advanced settings and then adjusting the exposure settings. If you do this (mind you if your day/night mode is set to color) you will see no difference. Any adjustment to the exposure does nothing. This means that if you are trying to see a license plate number on a moving car, or get an actual image of a moving person you are out of luck.  If you are monitoring statues or really slow-moving sloths then this won't matter. — Now an important addition to this, if you set the camera to black and white, it will allow adjustments to the exposure. You will notice that the shutter speed is maxed out at  1/1000 of a second which is equal to 1 ms. ——- So can we only make adjustments to the camera exposure on black and white mode, or am I missing something?   By the way, I have the cameras attached to the 16 port poe nvr.

    Currently using:
    RLN16-410 with 8 410 and 4 420 cameras
    RLN16-410 with 10 410 and 4 420 cameras
    RLN16-410 with 10 410 and 4 420 cameras
    RLN16-410 with 11 410 and 3 420 cameras
    RLN16-410 with 10 410 and 4 420 cameras

    I have an RLC-411ws that is able to read license plates at night (and day). I use a PC instead of NVR, and have the shutter set to 1-6ms, gain 1-95, 3D-NR turned off, adjustments to BLC and DRC, and black and white only as well. Key issues in making the plates read are the mounting of the cam to avoid headlight glare, as well as positioning such that the vehicles will moving orthogonal to the sensor plane to increase exposure time while mitigating smearing. Good enough plate reads that cloud-based OCR may be used as well.

    I assume you are using black and white mode? I am having the same problem as @anthmillward , these settings do nothing in ”color” mode.
    Adjustments to the exposure and gain do nothing, which seems like a (pretty serious) bug. Color mode is pretty gimped without being able to change the exposure settings.

    Yes. Another cam set up for color.
