SELISE Video Explorer T : Surveillance Made Easier

January 17, 2017

The process of converting surveillance footages into usable evidences has more to it than meets the eye. The sheer prospect of having to rummage through endless hours of footage and finding what you need is nightmarish. At the end of day, relevant interest groups such as forensic or surveillance experts do require necessary tools that make their work easier.

The Problem

It is commonplace in Switzerland to store surveillance videos from various sources in a central computer server- a Network Attached Storage unit, or NAS for short. SD cards inside cameras are, of course, another source. Viewing footage either directly from the camera or from a web browser is not much of an issue, but the same cannot be said when these videos are up for analysis.

This was particularly the case for Switzerland’s transportation authorities, whose job entails viewing endless hours of footages. Ill equipped and lacking the right tools, the sheer volume of data being handled beckoned a solution that  allowed more efficient viewing, extraction and analysis of the footages. Such a solution would add immense value to other entities such as law enforcement agencies.

The SELISE Solution

Initially crafted as a white label solution, SELISE Video Explorer T eventually grew to stand for a lot more. Known as VET for short, shaped up to become an advanced surveillance solution that supports a USB source and allows the user to review/analyze recorded videos from either a desktop or a laptop.

It can read information from both Linux (EXT2 and EXT3) and Windows (NTFS) hard drives, and currently supports AVI, MP4, H.264 & MJPEG formats for playback. Individuals can use markers to pinpoint events of particular interest on the footage, and maps to specify their locations. The application also boasts a wide array of options for viewing videos. At its best, the app can play up to six videos side by side, simultaneously. If necessary, the six frames can be merged and exported as one single video as well.

All in all, the multilingual and user friendly User Interface with a short learning curve makes for a very capable (and pretty awesome) analytical tool for relevant entities.

Technologies that have gone into the app of this video explorer are .Net, MVVM, Prism and XML.

The desktop application is targeted towards small to medium businesses such as retail stores, warehouses and hotels, as well as large scale transit-service providers such as airports and railways. In the future, the application could evolve into a camera companion or a video surveillance companion that directly interacts with the hardware to extract and organize information.

For now, the app complements the surveillance activities undertaken by RUF Telematik and adds a level of sophistication to it.

The Outcome

Without a shadow of doubt, the Video Explorer T has benefitted the Swiss transportation authorities by making information extraction smart. The app, equipped with maps, markers and split views, is designed to make analysis of surveillance videos much easier. It can also allow users to extract footages, export them conveniently and even convert them for playback where necessary. With its help, footages can be converted to evidence with greater ease, thus keeping the tool true to its purpose.

In the end, after having created something that allows easy extraction of crucial information from such large volumes of data, SELISE has once again produced a product that they can proudly call their own.
