You can hide the stream thanks to an event that disables/enables a
privacy mask on a device by pushing a button connected to the input port
or based on a schedule. This can be used for example to “disable” or
“turn off” the video stream on request or hide the view.
Requires firmware 5.40 or above and Privacy mask capability.
Step 1: Login on the device and add a black Privacy mask under Setup > Video & Audio > Privacy Mask. The privacy mask should take 100% of the field of view.

Step 2: Create a new Action Rule under “Setup > Action Rules > Add…” with the following parameters:
Name: Enable Mask
Trigger: Input Signal: Digital Input Port: Input 1: Active : Yes
Send HTTP notification to: My camera
Type: Send Notification
Recipient: New Recipient.
Step 3:
A pop-up window will open. Create a new recipient with the following parameters:
Type: HTTP
The URL should be the ip address of the camera followed by /axis-cgi/param.cgi
Enter Username and password of the camera and Save.

Step 4:
In Action Rule Setup select the recipient you have just created and add the following:
Custom Parameters: Add…
Name: action
Value: update
And another parameter:
Name: Image.I0.Overlay.MaskWindows.M0.Enabled
Value: yes
Then Save.

The Action Rule should look like that:

Step 5: Create a second Action Rule with the following differences:
Name: Disable Mask
Active: No
Custom Parameters: Add…
Name: Image.I0.Overlay.MaskWindows.M0.Enabled
Value: no
Then Save.
Note: Do not forget to change the value to no in the Trigger and in the Custom Parameter.

Result:
When input port of the camera is activated (button, switch,
detector...), the image on the device will then become black. If you
press again it will go back to normal. Instead of the Input Port you
could also use a scheduled event to switch at a defined time of the day.
