Video wall – Why rule based display is required

by Vijay on Wed, Jan 4, 2017

Video wall displays very large number of videos in a single screen. This will be highly ineffective if the displays cannot be managed manually or automatically according to rules.

Video wall is necessary for monitoring multiples of remote installations. However, if displays are not managed by rules, and if the number of locations under surveillance is large, it will be impossible to make any intelligent judgments of the situation prevailing at a specific location by looking at its video. So rule based display of the video is a must to make it intelligible.

Video wall is a display system in which multiple videos from multiple sources are displayed mostly in miniature mode, at a slower frame rate. This is used for simultaneously monitoring multiple locations. An example of the video wall is placed below.

When the number of locations to be displayed increases significantly, the size of individual displays becomes very small and the refresh rate is reduced to save bandwidth. If the video screens are not displayed according to predefined rules or does not have the capability to be searched / sorted by the operator, the very purpose of a video wall is defeated.

Webyfy has developed rule based video display on a video wall. These rules are based on alarms conditions or any other condition defined as per the application. For example: in an ATM monitoring situation, the rule can be “Display video in the video wall only if there is people presence in the ATM main cabin”. The technology developed by Webyfy enables multiple rules to be implemented in “AND” or “OR” logic. For example the video may be displayed for people presence OR if continuous glass banging is detected.

In addition, the operator can also search / sort the videos based on several parameters.

Rule based video display on a video wall increases the efficacy of monitoring and optimizes resources.
