Network cameras can send an email with a still image to alert users that an event has been triggered, but a still image is not enough to describe what is happening at real-time. Thanks to the SIP protocol, Milesight Network Cameras are able to make a call and transmit the live-view as well as real-time sound to the user’s VoIP telephone once an event is triggered, which is much more beneficial than sending an e-mail.
Today, SIP compatible devices are everywhere and the application is limitless. Users can simply dial the IP address of Milesight Network Cameras which integrated with SIP devices to see and hear what is happening whenever and wherever. With the support of SIP, Milesight Network Cameras could integrate with various VoIP telephony systems to build different ranges of solutions. Apart from watching the surveillance live view, users are even able to talk to whoever caused the event or triggered the alarm via build-in speaker or external speaker of Milesight Network Cameras.
