FYI, the support forum is public. For urgent, special, custom or private issues, it's recommended contacting us via email (or phone).
For "disable mouse right click option in iframe code", our engineers have supported now. You need to publish your camera first, then you can copy and paste the embed code into your HTML file. The embedded camera viewer iframe will not respond to mouse right click.
With regards to your second question of "also need live image some elements blurry system..Is it possible", it is better to be done on the camera side. In general, CameraFTP servers do not modify images/videos uploaded by your cameras (The files could be re-packaged, but they will keep their original quality). Otherwise, it will use huge amount of server resources since we have huge number of cameras uploading footage to our servers all the time.
