Hi,

I have M3045 camera.
I can change text overlay with browser command:
--------------------------------------------------------------------------------------------------------------
http://xxx.xxx.xxx.xxx/axis-cgi/adminpa ... ing=MyText
--------------------------------------------------------------------------------------------------------------
Works perfectly from webbrowser.

when I try to send request from 3rd party device I get HTTP response "OK"
--------------------------------------------------------------------------------------------------------------
GET /axis-cgi/admin/param.cgi?action=update&Image.I0.Text.String=MyText
--------------------------------------------------------------------------------------------------------------
but text overlay doesn`t change :/
even with login:
--------------------------------------------------------------------------------------------------------------
GET /axis-cgi/admin/param.cgi?Username=root&Password=admin&action=update&Image.I0.Text.String=MyText
--------------------------------------------------------------------------------------------------------------
what can be the reason?

BR,
Szewcu

Hi Krzyssztof Szewczyk,

You need to enable first:
http://<IP>/axis-cgi/param.cgi?action=update&Image.I0.Text.TextEnabled=yes

And then run the command:
http://<IP>/axis-cgi/param.cgi?action=update&Image.I0.Text.String=MyText

You need also to specify the authentication policy when requesting a vapix cgi => Digest (the browser does it for you).

I hope it helps.

after change the overlay text, you need reopen the stream to make it work.

another way is you can use the dynamic overlay which add "#D" to include text or set via VAPIX http://<servername>/axis-cgi/param.cgi?action=update&Image.I0.Text.TextEnabled=yes&Image.I0.Text.String=%23D, after that you can open the stream, then you can change the dynamic text
via
http://<servername>/axis-cgi/dynamicoverlay.cgi?action=settext&camera=1&text=aaaaaaaaaaa
