The CM7x camera is provided with an IR Remote Control for full control of the camera (PTZ, Presets, Manual/Auto Focus…) and use of the On-Screen Display (OSD) Menu (only shown on both SDI and HDMI camera outputs).


Once the camera onsite, you may need to recheck/change some settings (Flicker, Exposure mode, Color saturation..) in the OSD menu. To open it, press [MENU] on the IR remote control, use the Left/Right/Up/Down arrows to navigate, MENU button to get back. Below are the main categories that compose the OSD menu:


  • LANGUAGE (English, Chinese)

  • SETUP (Visca/Pelco settings, autoflip..)

  • CAMERA (Exposure modes and Flicker, Color (Saturation), Image, Focus, Noise reduction settings...)

  • P/T/Z (Speed settings, Image freezing...)

  • VIDEO FORMAT (different supported Resolutions...)

  • NETWORK SETTINGS (dhcp or fixed IP address)

  • VERSION (firmware levels)

  • RESTORE DEFAULT

 

 

Here are some examples of some settings that would be good to recheck/change:


1- CAMERA > EXPOSURE > Flicker

If the signal flickers due to the artificial lighting, enable the anti-flicker by selecting the most convenient option between 50 or 60Hz (1)



2- CAMERA: EXPOSURE > Mode :

  • Choose AAE exposure mode and set the iris at F3.4, maximum F4.0 (2)

  • If AAE is not giving good results, switch back to the AUTO exposure mode (3)



3- CAMERA > COLOR > Saturation

Try with 120 or 130% especially with IP streaming (4)



4- VIDEO FORMAT: to select a different video resolution if needed (If the monitor does not display the image because it does not support the resolution sent from the camera, see How do I change the HDMI or SDI output resolution of my camera?)



5- RESTORE DEFAULT : Finally if you played with too much options without getting the desired result, you can start from scratch by resetting back to default the camera (choose the YES option, the camera will reboot)


APPENDIX


(1) See article “Anti flickering”. Depending on lighting types, such occurrences may not be improved with the anti-flicker setting. It would be so recommended to set -only possible within the Manual or SAE exposure modes- the shutter speed to 1/100s in areas of 50 Hz power grid frequency, and to 1/60s in areas of 60 Hz power grid frequency


(2) This AEE exposure mode is usually expected for installations with fixed lighting conditions (studio for instance). By default, the camera opens the Iris as far as needed (F1.8) to let in as much light as possible, however this can introduce eventual focus/depth of field issues. So closing the Iris a couple of steps (from the default F1.8 to F3.4 or F4.0) creates a more focused image because the light entering the lens through a smaller hole, creating a more focused beam of light on the sensor


(3) The AUTO exposure mode is usually expected for installations with natural/dynamic light (office spaces with windows for instance)

 

(4) IP streaming takes away some color information, we do advise to put the color saturation a little higher than 100% (120% or 130%?) to avoid getting a washed-out image
