The choice of the user mode depends on the monitoring objectives. The modes differ in settings, which affect the accuracy of the received data, as well as the consumption of traffic and battery power usage.
You can add your own user mode with an arbitrary configuration of settings. To do this, tap Add usermode, indicate the name and make the necessary adjustments. Any mode can be changed or deleted. Tap three vertical dots to the right of the mode.
Operation mode
The operation mode of the service is determined by three parameters. Depending on the monitoring objectives, select the settings of data collection and data sending and, if necessary, start and stop of the service by event.
Data collection
Three data collection modes are available.
| Data collection mode | Description |
|---|---|
| Continuous | The position data is collected continuously and have high accuracy. This method is characterized by a high consumption of traffic and battery power. |
| By timeout | The position data is collected regularly after the time interval specified in the Timeout field (by default — 5 minutes). The less the timeout is, the more accurate the data is. The consumption of traffic and battery when using this method of data collection depends on the selected timeout. |
| Smart mode | The data about the location is collected only when the unit is moving. As soon as the movement of the unit is detected, the positioning service turns on. |
Additional settings are available for the Smart mode.
Motion detection
The following methods can be used to detect the motion:
| Method | Description |
|---|---|
| Activity recognition | In different versions of Android the methods of activity recognition may differ, that is why this method should be tested for each device individually. |
| Accelerometer | This method can be selected for walking. Its drawback is that the beginning of movement can be detected even when the device is just shaken. |
| Wi-Fi | This method of motion detection is recommended when Wi-Fi is used at all parking points. The algorithm of operation is as follows: if there is a Wi-Fi connection, the unit is considered to be standing, if there is no Wi-Fi, the unit is moving. This method is not very accurate as there is a large number of Wi-Fi networks in the cities. |
| GSM | According to this method, the beginning of the motion is detected based on the location of the base stations of the cellular communication networks. The algorithm is as follows: the device determines the location of the base stations; after some time the location is determined again; if the position changes, the beginning of movement is recorded. Since errors may occur while detecting the position of base stations of the cellular communication, this method is not highly accurate and its operation should be tested for each device individually. |
| Significant motion sensor | According to this method, the beginning of motion is determined by a significant movement of the unit. It means that the movement resulted in changing the position of the unit. This method is considered to be of high-precision and can be used even when traveling on foot. The operation of the method must be tested for each device individually. |
Motion detection timeout
The time at which the device should detect the state of movement.
Detect motion continuously
This option improves the accuracy of motion detection, but significantly increases battery power consumption.
The Motion detection timeout and Detect motion continuously options are mutually exclusive.
This setting can be used with the By timeout data collection method. It indicates the time after which the device must collect data.
Data sending
Data can be sent continuously, by timeout or manually.
| Data sending mode | Description |
|---|---|
| Continuous | According to this method, the location data is sent to the server constantly (as it arrives and if there is an Internet connection). The continuous method is characterized by high battery usage. |
| By timeout | According to this method, the location data is sent to the server regularly, after a specified time interval, after which the mobile device returns to sleep mode. |
| Manual unload | According to this method, all the collected location data of the unit is sent to the black box, from which the user can subsequently send it to the server manually. |
Timeout
This setting is only relevant for the By timeout data sending method. It indicates the time after which the device must send data.
Work in roaming
This option allows you to enable or disable the sending of data in roaming.
Start/Stop by event
In this section, you can configure to automatically start or stop the application.
| Option | Description |
|---|---|
| Auto startup | When this function is activated, the service automatically starts in the background after the mobile device is rebooted. |
| Work while charging | When this function is activated, the service starts automatically when the charger is connected and stops when it is turned off. |
| Work by schedule | The service can be automatically started or stopped according to the set schedule. The created work intervals are displayed only when this option is activated. |
| Add schedule | This setting becomes available only when the Work by schedule option is activated. To create a new schedule, tap the Add schedule button, specify the time interval and days of the week when the service should be started. |
Data settings
Location source
This setting allows selecting the methods of location source detection. The following options are available: Fused (Google) (available by default), GPS, Wi-Fi and mobile networks and GPS, Wi-Fi and mobile networks. The corresponding options must be also activated in the settings of the mobile device itself.
Filtration of messages
Max accuracy
The maximum value of the error with which the messages can be sent. If it is exceeded, no message is sent to the server. This parameter is taken into account regardless of whether message filtering is enabled or disabled.
Filtration of messages
If this option is enabled, the filtering conditions specified below are applied to send messages to the server. Filtering applies only to messages received via GPS. In case location is detected by the cell towers or Wi-Fi, the messages have zero values of speed, course, the number of satellites and the accuracy can exceed 2000 meters. That is why they are not filtered.
Below are the settings according to which filtration should be carried out. The Logical OR operation is applied to the settings, that is, a new message is generated when any of the specified conditions are met.
| Setting | Description |
|---|---|
| Min time | The minimum time interval between messages sent to the server (in seconds). According to this setting, a new message is generated after the specified time after the previous message. |
| Min distance | According to this setting, a new message is generated if the unit has passed a distance equal to or exceeding the specified value since the previous message. |
| Change in course | A new message is generated if the angle of the course change (i.e., the direction of travel) in degrees changes by an amount equal to or greater than the specified value. |
| Change in speed | A new message is generated if the speed difference (the speed difference between the previous and current messages) is changed by an amount equal to or exceeding the specified value. |
If the filtering settings are too strict, messages will not be generated.
Additional parameters
In this section, you can specify additional parameters that must be received from the unit in messages.
| Option | Description |
|---|---|
| LBS data | When this option is activated, the sent messages contain data about nearby base stations of cellular operators (for example, base station identifiers). |
| Provider name | When this option is activated, the sent messages contain the p parameter, the value of which indicates the source of the positional data. |
| Accuracy | When this option is activated, the sent messages contain the a parameter, which shows the accuracy of the positional data (in meters). |
| Battery level | When this option is activated, the sent messages contain the b parameter indicating the battery level of the device (in percent). |
| Last status | When this option is activated, the sent messages contain the last specified state of the unit. |
| Mock location | When this option is activated, the sent messages contain the mc parameter. Its values are measured in bits:
Values of the parameter can be summed up. For example, if 3 arrives in the parameter, it means that conditions 1 and 2 are met. |
| Service messages | When this setting is selected, the message contains the following parameters:
Sent messages also contain the Is parameter. This parameter is sent when the accuracy of the location determination in the device settings changes. Possible parameter values:
