Systems are known to protect people and assets within secured areas. Such systems are typically based upon the use of one more sensors that detect threats within the secured area.
Threats to people and assets may originate from any of number of different sources. For example, an unauthorized intruder, such as a burglar may present a threat to assets within a secured area. Intruders can also injure or kill people living within the area.
Intruders may be detected via switches placed on the doors or windows of a home. Alternatively, the area may be monitored via a number of security cameras.
The video from such cameras may be presented on a display at a guard's station. Alternatively or in addition, the video may be continuously recorded in a video archive by a recording device of the security system.
The recorded video may be used as evidence of criminal activity, such as a break-in or theft. However, the relevant video may only occupy a few frames of many hours of continuous recording.
In the case where the criminal activity is not immediately detected by a sensor of the security system or by a guard monitoring the video, then the video must be reviewed at a later time to identify the relevant portions. This may involve a guard or some other designated person reviewing hours of video from one or more cameras in order to find evidence of the event from one or more cameras.
During the course of an investigation, the reviewer may identify and save the contents of a number of different portions of the video with repetitive and often confusing descriptions. Accordingly, a need exists for better ways of reviewing relevant video.
