VTO-VTH VTO 2211GP-WP & VTH2421FW-P Dahua configuration. 

Дякую !!!

I want to thank you for this training and especially for all the details you have presented. A question to ask yourself, is it possible to make a call from the DHI-VTH2421FW-P monitor to a smartphone through the DMSS application? because I can't find on DHI-VTH2421FW-P the QR of the GDSS application

What is the SD card slot used for?
