Dinion2X IP Camera Advanced Mode | en 71 A negative value gives more priority to average light levels; a positive value gives more priority to peak light levels. Video iris lens: choose an average level for best results (peak settings may cause oscillations). Speed Adjust the speed of the video level control loop (Slow, Medium, or Fast). For most scenes it should remain at the default value. 9.6.3 Shutter/AGC Shutter - Fixed - allows a user-defined shutter speed. - AES (auto-shutter) - the camera automatically sets the optimum shutter speed. The camera tries to maintain the selected default shutter speed as long as the light level of the scene permits. - FL - flickerless mode avoids interference from light sources (recommended for use with video iris or DC iris lenses only). Default shutter / Fixed shutter Select the shutter speed (1/60 [1/50], 1/100, 1/120, 1/250, 1/ 500, 1/1000, 1/2000, 1/5000, 1/10K) for the default (AES) or fixed value. In AES mode, the camera tries to maintain the selected shutter speed as long as the light level of the scene is high enough. In Fixed mode, select the shutter speed. Actual shutter Displays the actual shutter value from the camera to help compare lighting levels and optimum shutter speed during setup. Sensitivity up Selects the factor by which the sensitivity of the camera is increased (OFF, 2x, 3x, etc. to a maximum of 10x).
