Device Manager Pane

The Device Manager pane displays the following options:

Devices are digital video recorders that are fitted inside vehicles. They are listed under the Devices folder within Evidence Manager. As vehicles travel, cameras inside the vehicle record video continuously, and save the recordings to these recorders. When vehicles arrive into designated depots, videos stored in the recorder memory are downloaded to the Depot Manager server over a network. Sometimes, videos are also downloaded by physically connecting the hard drives from the recorders to workstations. The Devices option within Evidence Manager allows you to view device properties, view diagnostics, configure devices, upload and download configuration files, access device logs, and so on.

docking station provides a way for hard drives from compatible recorders to connect to Evidence Manager. Hard drives can be physically connected to a computer or a network. Evidence Manager automatically searches for compatible hard drives connected to computers within the network, and lists them under the Docking Stations folder. If a hard drive is removed from the computer, it disappears from the Docking Stations folder.

Once a hard drive is added to the tree, you can perform operations such as:

  • Play a video from the beginning, using the Go to date option on the timeline bar to filter the video to any date and time
  • Use video player controls such as fast forward, fast reverse, and play/pause to control the video
  • Access log files

Workstations are other computers on which Evidence Manager is installed. Because instances of Evidence Manager on different workstations communicate over the same network, you can use your instance of Evidence Manager to access videos from other workstations. However, the ability of Evidence Manager to connect to other Evidence Manager instances depends on the messaging protocol you select.

Evidence Manager provides a way to view videos from devices by physically connecting the devices to a computer. The Service Portoption allows you to physically connect a device, and directly view videos stored in its hard drive. When used this way, a hard drive is connected by means of a compatible cable to a computer on which Evidence Manager is installed. The Service Port option is used to set an IP address for the hard drive, so that Evidence Manager can connect to it.

Map View

Evidence Manager can track vehicles, and display their positions on an in-application map. If a device has the capability of recording GPS data, Evidence Manager uses this data to track the route of the vehicle in which the device is fitted. Typically, Evidence Manager reads the coordinates within the video files to determine the position of the vehicle at a given time. Multiple positions together define the route that the vehicle travels. Vehicle tracking on maps is only available on Live/Playback video playing at normal speed. On the map, the vehicle position is represented by a tracking line, along with the vehicle’s location and speed information.

To view tracking information on the map, Evidence Manager must be connected to the internet. Once connected, Evidence Manager connects to the local map of your area on https://www.openstreetmap.org/about, in order to display the local map inside the Map View window. If Evidence Manager cannot connect to the internet, a blue screen appears on place of the map.

Video Display Area

The video display area plays videos recorded earlier, or currently recording. Once a video is accessed, it starts playing in the standard tile layout as label D displays. Evidence Manager supports the following standard layouts: 1×1, 2×2, 3×3, 4×4, and 5×5. The custom tile layout has 1 large tile and 7 smaller, surrounding tiles.

Metadata View Pane

The Metadata View pane lists all the events that are configured within the device to which Evidence Manager is currently connected. These events appear as a color-coded list, with a Yes/No entry against each type of event. When an event occurs, the entry changes from the default value of No to Yes, thereby indicating the occurrence of an event.

Bookmarks Window

The Bookmarks window displays a list of bookmarks that are added to a video. Bookmarks are notes that represent additional details related to a particular clip within a video file. Bookmarks provide better context of the video, and are also useful for finding specific sections in a video on another day.
