These systems consist of one or more digital color cameras and a scalable Digital Video Recorders (DVRs) and Network Video Recorders (NVRs). These devices are usually controlled through a computer configured with audio channels and VOIP capabilities. These systems allow for listening-in to whatever is happening in an area and recall the video and audio at a later time. VOIP capability is used so persons in the monitored area can pick up the phone and immediately talk to the central station personnel who are looking-in and listening-in to the situation. An “Interactive” system is one that allows the monitoring station personnel to not only listen-in but to “talk down” over speakers and actually “intervene”. These systems allow those with authority to look at live video/audio feeds and recordings. The features can be accessed over a network or over the Internet by using a web browser. JS&A can provide a complete new digital system or upgrade existing analog systems.
