How to Change Exposure Settings based on Time Task

Introduction

Due to differences in the ambient light, there maybe be problems with the image either during the day or night. It maybe necessary to deploy separate exposure setting for night and day to counter this problem. We can configure MOBOTIX IoT cameras to automatically change their exposure settings based on a Time Task.

Procedure

  1. Go to http://<ip_cam>/control/exposure and configure the camera so that the images are perfect during the day.

  2. Go to http://<ip_cam>/control/control?list&section=exposure and copy and paste the whole page on a text file

  3. Wait till it gets dark…

  4. Go to http://<ip_cam>/control/exposure and configure the camera so that the images are perfect during the night.

  5. Go to http://<ip_cam>/control/control?list&section=exposure and copy and paste the whole page on a text file

  6. Compare the two files and check out which parameters are changing. We will use them to configure the IP Notify profiles

The following profile will bring the exposure settings back to factory defaults:

IP Notify Profile Name: Day
Predefined Configuration: Custom Configuration
Destination Address: 127.0.0.1:80
Send Order: Parallel send to all
Transfer Protocol: HTTP/1.0 Request
CGI-Path: /control/control
HTTP Authentication: admin:meinsm
Notification Data: Plain text
Message: set&section=exposure&automatic=auto+auto&brightness=0+0&backlight=4+4&ca_exp_window_type=top+top&ca_avg_intensity=300+300&ca_exp_minavg=100+100

The following profile will switch off all the amplifiers and delivers pretty nice images during the night (not suitable for Security applications!):

IP Notify Profile Name: Night
Predefined Configuration: Custom Configuration
Destination Address: 127.0.0.1:80
Send Order: Parallel send to all
Transfer Protocol: HTTP/1.0 Request
CGI-Path: /control/control
HTTP Authentication: admin:meinsm
Notification Data: Plain text
Message: set&section=exposure&automatic=off+off&brightness=0+0&backlight=-10±106ca_exp_window_type=full+full&ca_avg_intensity=200+200&ca_exp_minavg=0+0

The following profile saves the configuration into the flash memory:

IP Notify Profile Name: StoreConfig
Predefined Configuration: Custom Configuration
Destination Address: 127.0.0.1:80
Send Order: Parallel send to all
Transfer Protocol: HTTP/1.0 Request
CGI-Path: /admin/rcontrol
HTTP Authentication: admin:meinsm
Notification Data: Plain text
Message: action=storeconfig

  1. Use the above profiles on a schedule basis

a. Go to http://<ip_cam>/admin/timetasks and create 4 time tasks:

IP Profile Day 0 7 * * * (every day at 7:00)
IP Profile StoreConfig 1 7 * * * (every day at 7:01)
IP Profile Night 0 18 * * * (every day at 18:00)
IP Profile StoreConfig 1 18 * * * (every day at 18:01)

Hi Michael,

Thank you for the most interesting solution to a very common dilemma! Could you please let me know if I can apply your solution also to my cameras: D16 night optic (2 wide angle lenses), D16 night optic pano, Q26 day optic and Q26 night optic?

Kind regards,
