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.
