IP video surveillance uses a company's existing network and Internet technology to transmit images from analog cameras and/or IP cameras over public networks. These systems allow live streaming video and still image transfer (both one-way and two-way) into a standard, easy-to-use Web browser, so video can be viewed in real time.
Such systems deliver a great deal of additional functionality. For instance, they provide motion detection, auto time and date stamps, easy transfer of visuals, and pre- and post-alarm messaging. If an event is occurring you can log on to the system remotely to see what's happening in their offices and businesses. Users have found that IP surveillance:
- Enhances and expedites law enforcement and emergency services
- Contributes to reliable identification of criminals and reduces the need for eyewitnesses
- Can be used locally and remotely
- Integrates easily with CCTV cameras, thus preserving legacy investments
