On of the first projects this year is the integration of the Dahua VTO-2000A-C-2 with an Asterisk telephone system. Goal of this project is to send the video stream of the camera module to the existing Grandstream WP820 phones when the bell button is pushed.
The system should work without a Dahua VTH display module, only the VTO camera module, the Asterisk server and the SIP handsets.
Big advantage of the Dahua VTO-2000A video intercom is the modular system which can be extended by bell button/RFID/fingerprint modules.
