Hi,

I try to use the "SetMask" command by API.
The camera is in the NVR's channel 0.
I try to create and delete one mask with the API.

The URL is something like that:

 https://*******************/api.cgi?cmd=SetMask&user=**************&password=*********

I've created a mask with the client and I've tried to delete it wih the API...
I've tried to create a mask with the API...
I've tried a lot of commands like this :

[{"cmd":"SetMask","action":0,"param":{"Mask":{"channel":0,"enable":0,"area":null}}}]
[{"cmd":"SetMask","action":0,"param":{"Mask":{"channel":0,"enable":0,"area":[{"screen":{"height":0,"width":0},"block":{"x":0,"y":0,"width":0,"height":0}}]}}}]

[{"cmd":"SetMask","action":0,"param":{"Mask":{"channel":0,"enable":1,"area":[{"screen":{"height":860,"width":1528},"block":{"x":0,"y":0,"width":1528,"height":860}}]}}}]
[{"cmd":"SetMask","action":0,"param":{"Mask":{"channel":0,"enable":1,"area":[{"screen":{"height":860,"width":1528},"block":{"x":0,"y":0,"width":1528,"height":860}},{"screen":{"height":0,"width":0},"block":{"x":0,"y":0,"width":0,"height":0}},{"screen":{"height":0,"width":0},"block":{"x":0,"y":0,"width":0,"height":0}},{"screen":{"height":0,"width":0},"block":{"x":0,"y":0,"width":0,"height":0}}]}}}]

I've received always the same response :

[{"cmd":"SetMask","code":1,"error":{"detail":"set config failed","rspCode":-13}}]

I've tried to change the "enable" parameter to 1 or 0, and it's the same.

I don't understand how work this command.

Can you help me please ?

Thank you !
