3. Inappropriate browser security setting: Please ensure that your security setting in Internet Explorer
allows the installation of ActiveX component by adding the IP address of the camera to the list of trusted
sites in Internet Explorer.
If you've gone through all of the above steps but are still unable to receive video/audio on the browser, please
close all the browser windows and delete the "Compro Embedded" folder found under "(OS Drive):\Program
Files". (If you're using 64-bit windows, look for "(OS Drive):\Program Files (x86)".) And open your web browser
and log in to the IP camera again to reinstall the ActiveX client. In addition, if you encountered the error
which the browser returns "213 file not found", please restart your computer, as it should help in this situation.
