Viewing Telemetry Data


Telemetry data is information about vehicle location and performance captured from sensors located in the DVR and the vehicle.

As explained in the previous section, Viewing DVR Video Files, users can access telemetry information under the Telemetry tab, located within the Video Data section on the left side of the screen.

However, vMax View also offers the alternative of viewing telemetry data in the Playback Window for user convenience. You can see these two possibilities in the figure below.

Viewing Telemetry Information in the Playback Window

To display telemetry data in any view section of the Playback Window:

  1. Right-click on that view section (preferably an unused section).
  2. In the drop-down menu, move the cursor to Display Telemetry and select the preferred data option (see figure below). The selected option will be displayed in the corresponding view section.

Telemetry Data Options

There are five different Telemetry data options that users can select in vMax View: GPS, Speed, Signals, Idle and G-Sensor.

Let’s see the information these options provide in more detail and how they are displayed in the Video Display area with the aid of the following figures:

  1. GPS. Vehicle position tracking and data is collected using the GPS locator in the DVR. The vehicle’s position and route (segment in magenta) displays in map view when the HDD is connected to vMax View or a video clip is opened and one viewing channel is set to display GPS telemetry.

GPS data is also displayed in the Video Data Telemetry tab.

  1. Speed. Both current speed and excessive speed events can be displayed in miles per hour (mph) or kilometers per hour (km/h).

    Recorded speed events are also displayed in the Video Data Telemetry tab.

  1. Signals. Up to ten signals can be connected to the DVR. Double click a signal name to edit it. To show and hide signals, click the plus/minus (±) symbol on the header of the signals window and select or deselect as preferred.

    Signals are also displayed in the Video Data Telemetry tab.

  1. Idle. When a vehicle with a DX series DVR is stationary with the engine running for a length of time, that interval can be detected. This may trigger event and alarm recordings depending on the Idle Limit Timer. The Idle Limit Timer setting is selected on the Diagnostic Display menu in the DX series DVR.

    Recorded idle events are also displayed in the Video Data Telemetry tab.

  1. G-Sensor. Detects forces on the DVR created by vehicle movement (G-forces).

    Recorded G-Sensor events are also displayed in the Video Data Telemetry tab

NOTE: G-Sensor information depends on DVR/NVR configuration

    • Devices with internal G-Sensor units (including the HX, NX, DX, TLHD and TX series), and H series equipped with the external G-Sensor MDL, report motion from front to rear (X), left to right (Y), top and bottom (Z), and the force of motion (V).
    • MX and TL series DVRs equipped with the external XELR-8 G-Sensor report an alarm when acceleration thresholds are exceeded.

In addition to the general G-Sensor information window, you can also have a more detailed extended view. To display this:

  • Select the single view option in the Video Display area.
  • Right-click on the view area and select Display Telemetry and then G-Sensor.

This illustration shows how G-forces affect the bus from the front, rear, sides, top and bottom. G-Sensor defaults are:

    • Front X+, Rear X-
    • Left Y+, Right Y-
    • Top Z+, Bottom Z-

You can also use the Front and Bottom drop-down menus to assign + or – axis as preferred.
