Location and tracking

Zenda VT-1 is embedded with GPS. It does not support A-GPS, or GLONASS technology.

As the back-up, when no satellites signals are available, it uses Cell ID location (also known as LBS-tracking).

Mobile networks

Zenda VT-1 has a Quad-band GSM 2G module that allows to operate it all over the world.

Power supply

External power supply might be 11-36V, which makes possible to use Zenda VT-1 with all car models.

Sleep mode

Zenda VT-1 features the Smart Sleep mode

The smart sleep function works in conjunction with the following.

Scenario 1: When the ACC detection line has not been used.

With no interruption for consecutive 15 minutes, the tracker enters smart sleep mode. In this way, the GPS module stops work, and the tracker stops uploading data. Heartbeat reports about GPS invalid will be sent to the platform every 60 minutes (the default interval can be changed). If vibration occurs, the tracker will awake and continue to operate and report data at the specific interval. Heartbeat reports will be also resumed.

Scenario 2: When the ACC detection line has been connected.

If the ACC is on, the tracker will operate normally and report data at the specific interval.
If ACC is off, without any vibration, the tracker immediately enters smart sleep mode (as same as Scenario 1); Heartbeat reports about GPS invalid will be sent to the platform every 60 minutes (the default interval can be changed). If vibration occurs or the engine starts, the tracker will awake and continue to operate and report data at the specific interval.


  • When the tracker is being charged with a USB cable, it will operate normally, but will not enter smart sleep mode.
  • Under smart sleep, the tracker has low power consumption. The tracker with built-in battery can sustain up to about 50 hours.
