Viewing Video Surveillance Options
Surveillance video is ultimately viewed by people and security staff. Of the video that is viewed, the most common use is for historical investigations. Some surveillance video is viewed live continuously by on-site security personnel, generally in retail to spot shoplifters and reduce shrinkage. In public surveillance it is typically to identify criminal threats. Most live video surveillance is done periodically in response to a detected threat or to check up on the status of a remote or non-staffed facility.
4 Core options:
- Local Viewing: directly from the DVR, NVR or servers is ideal for monitoring facilities on-site. This lets the video management system double as a viewing station, saving you the cost of setting up or using a PC. This approach is most common in retailers, banks and small businesses. It is also used where on-site staff or security monitor live video surveillance feeds.
- Remote PC Viewing:In this approach, standard PCs are used to view live and recorded video. Either a proprietary application is installed on the PC or a web browser is used. Most remote PC viewing is done with an installed application as it provides the greatest functionality. However, as web applications mature, more providers are offering powerful web viewing. The advantage of watching surveillance video using a web browser is that you do not have to install nor worry about upgrading a client. Cloud storage and viewing services are now also available.
- Mobile Viewing: (Smart Phones) allow security operators in the field to immediately check surveillance video. As a physical presence and mobile security guards are common in security, mobile viewing has great potential. Capabilities and interest in mobile phone or smart phone applications to view live security camera feeds is growing with the introduction of the Apple iPhone
and Android poerating systems. Blackberry smart phones also allow mobile phone CCTV video feed viewing.
- War Room Video Boards: are ideal for large security operation centers that have hundreds or thousands of cameras under their jurisdiction. Video walls provide very large screens so that a group of people can simultaneously watch. This is especially critical when dealing with emergencies and risk situations. Video walls integration can automatically display feeds from locations where alarms have been triggered.
