To change the video and audio settings from a browser, we have to enter the IP of the camera in the address bar:
After accessing the camera with your credentials, we must access "CONFIGURATION" and then the left menu, VIDEO AND AUDIO.
Remember that in some models of IP cameras the image is not encoded in H265 or H265+, therefore the option to modify the compression format may not offer the options mentioned above.
In this other field is where you can modify the values of Bitrates, frames and bit rate type to save the bandwidth used by the camera.
In the image below we can see that the bitrate has decreased a lot by just changing the Video Enconding to H.265 and then enabling H.265+.
We could save even more bandwidth by changing other parameters (such as image resolution), but that depends on each installation, it is not always mandatory.
