You can also adjust brightness and contrast to improve the image. Conversely, if it is still bright, then drop down in time to get a faster shutter. Try not to go above 16.67ms (but certainly not above 30ms) as that tends to be the point where blur starts to occur. Then have someone walk around and see if you can get a clean shot. until you find what you feel is acceptable as an image. Then at night, if it is too dark, then start adding ms to the time. You have to play with it for your field of view. In the daytime, if it is still too bright, then drop the 4ms down to 3ms then 2ms, etc. What do we want, a nice static image or a clean image when there is motion introduced to the scene? The nice bright night static image results in Casper blur and ghost during motion LOL. That faster the shutter, the more light that is needed. Now what you will notice immediately at night is that your image gets A LOT darker. Auto could have a shutter speed of 100ms or more with a gain at 100 and shutter priority could result in gain up at 100 which will contribute to significant ghosting and that blinding white you will get from the infrared. Go into shutter settings and change to manual shutter and start with custom shutter as ms and change to 0-8.3ms and gain 0-50 (night) and 0-4ms exposure and 0-30 gain (day)for starters. Most people select shutter priority and run a faster shutter than they should because it is likely being done at 100 gain, so it is actually defeating their purpose of a faster shutter.īut first, run H264, smart codec off, CBR, and 8192 bitrate to start, along with 15 FPS and 15 i-frame. The higher the gain, the bigger the noise and see-through ghosting start to appear because the noise is amplified. Many people do not realize there is manual shutter that lets you adjust shutter and gain and a shutter priority that only lets you adjust shutter speed but not gain. 15 FPS is more than enough for surveillance cameras as we are not producing Hollywood movies. It is the shutter speed that prevents motion blur, not FPS. In my opinion, shutter (exposure) and gain are the two most important parameters and then base the others off of it.

Any camera can be forced in color and look great for a static image, but motion is a blur.

Surveillance cameras rarely do good on default auto settings like exposure/shutter at night. As mentioned, the settings are unique to each field of view and available light.
