Thermal control in the AI-14 dashcam, is designed to ensure continuous operation even in high temperature conditions. The main processor in the AI-14 dashcam, the i.MX8M+, has a critical temperature threshold of 105°C, beyond which the dashcam automatically switches off to prevent damage. The thermal control feature avoids reaching this extreme temperature, and works to ensure optimum conditions for continued video recording,
Several components contribute to heat generation in the AI-14 dashcam, aside from the video recording. Key contributors include:
-
LCD Display - The screen used for playback and monitoring.
-
Cellular Modem - Responsible for mobile data connectivity.
-
Wi-Fi - Enables wireless network connections.
-
MV+AI Processing Unit - Used for AI and processing tasks.
The thermal control management automatically ceases high energy functions at high temperatures. This may impact device functions in different ways.

The following are shut down:
|
|
Between approximately 95°C and approximately 80°C. |
The device remains in Thermal Control mode until the i.MX8M+ processor's temperature decreases to approximately 80°C. |
Same as above |
|
The temperature reaches approximately 80°C. |
Once the temperature reaches 80°C, the device automatically re-enables the functions and processors that were disabled. |
Normal operations resume |
Note
Thermal control mode can occur when the AI-14 dashcam is online, or in standby mode.
If the AI-14 dashcam enters thermal control mode, the Thermal Shutdown Enter event is triggered in the cloud. This event can be enabled or disabled, through event settings in the Surfsight® Portal.
