Recovery Mode - Remora3

Recovery mode can be used to help recover a stolen asset. 

When set, a device reports more frequently, and begins 'live tracking' when on the move.

NOTE: While there are no additional charges involved in setting Recovery Mode, the following points needs to be kept in mind

  • Increased data usage will be seen until Recovery Mode is deactivated.
  • Significantly increased battery usage for the duration Recovery Mode is active. 

Given the above, we select an expiry time when setting Recovery Mode (i.e. Expire after 12 hours) - so that the device leaves this mode and doesn't remain in recovery mode indefinitely, draining the battery life.

Setting Recovery Mode

There are multiple ways to set recovery mode on the Remora3.

Via the OEM Server UI
Select the device, and from the "Device Operations" tab, select "Set Recovery Mode".

Through Telematics Guru
Go to Assets->Manage Assets-> Select the asset. From the cog menu on the right hand side, select "Enter Recovery Mode".

Through Telematics Guru Mobile App
The eye symbol on top of the asset indicates Recovery Mode. If it is greyed out (has a line through it), then recovery mode is not set. If the eye is solid, then recovery mode has been set.

Via a 3rd Party Server
Recovery Mode can be set by either sending a command directly to the device or via the OEM Web API. DM support can provide the required integration documents

Remora3 Recovery Mode Behavior and Parameters

When in normal operation, the device will sleep in a low power state. Only waking up periodically to acquire a GPS fix and/or upload. Details of normal operation given here:

When in Recovery Mode:

  • The device detects trips based on accelerometer activity (jostle mode)
  • Once in trip, the GPS is left on continuously, acquiring regular fixes
  • The modem is left on and the device attempts to remain continuously connected to the server.
  • The GPS mode is forced to Performance Mode

Below are the default update rates when a device is set to Recovery Mode. These parameters are configurable to suit your use case, but we recommend any changes made to the parameters be tested before deployment.

Heartbeat Period30 minutes
In Trip LoggingUpdate Rate
30 seconds
Trip End Timeout
10 minutes

Some Recovery Mode parameters are configurable, from the system parameters tab in OEM select Add Advanced Parameters-> Recovery Mode Setup.

These parameters do not need to be touched for the majority of use cases.

If you have some special requirements, contact our support team for assistance.

When will the device enter recovery mode?

Under normal operation, the Oyster3 sleeps in a low power state (with its cellular modem off, not connected to the network). This means that if we then set Recovery Mode 'on' from the server - it will not be actioned until the next upload/connection.

Consider the example of a device set to upload hourly.

  • 10:00am - device uploads
  • 10:10am - recover mode is set on the server
  • 11:00am - Device connects in again, gets the message and goes into recovery mode.

We need to choose the parameters carefully so that in the event of a theft, the device can go into recovery mode with an acceptable delay in from setting the device in recovery mode and the time the device actually goes into recovery mode.

A sensible frequent In-Trip Upload parameter can be a good option to consider. By default, when an Oyster3 is in trip, it uploads every 30 mins. So in that instance, the device will behave as below

  • 10:00am - device uploads
  • 10:10am - Recovery Mode is set on the server
  • 10:30am - Device connects in again, gets the message and goes into recovery mode.

If the default in trip upload rate needs it can be configured from Parameters->Edit System Parameters->Basic Tracking.

Note adjusting this rate will affect battery life.

Automatically Enable Recovery Mode After hours

It may be the case that any after hours usage is unauthorized, or is due to attempted theft.

The Oyster3 can be configured to automatically go into recovery mode if the device goes into trip after hours. This is set up from Parameters-> Edit System Parameters->After Hours-> Auto Recovery Mode Expiry. 

The Auto Recovery Mode Expiry value is in hours. If set to "1" for example, the recovery mode will be activated for an hour since the trip starts. Setting this value to "0" will disable the after hours auto recovery mode.

Apart from entering auto recovery mode, alerts can be configured based on after hours usage. For more information, see Alert on After Hours Movement.

NOTE: Take care with this feature. If the device unexpectedly makes many trips, or the parameters are configured such that many trips are started/ended, you will flatten the batteries. Contact support if you are not sure.

If the user decides to exit recovery mode on the server, the device will have to end its trip first, else the device will re-enter recovery mode.
