Version 2024.2
Release Date: 02.04.2024
Device Schedule (Running/Standby)
The device schedule allows you to define time slots when the device should be in operational mode (device state: running) or in power saving mode (device state: standby).
The power saving mode is mostly relevant for the battery powered system BMA Mobil since it extends the usage time for a single charge.
In our measurements, the BMA Mobil reduces the power consumption during standby by about 55%.
How to enable the schedule for a device?
Open a device in the control center and select the tab schedule
Switch the toggle to Enabled and select desired time slots when the device should be operational
Save Schedule
What will happen during standby?
The device reduces the power consumption by pausing the video signal processing.
Functions that are not available during standby:
No events will be generated
No camera image is visible
No event triggers can be configured
Functions that are available during standby:
The device will be online in the Control Center, including available device health, logs, and reboot functionality.
Wake-up the device from standby (→Set the toggle to Disabled)
What is the expected battery lifetime?
In our measurements the BMA Mobil consumes 1,07A when active and 0,48A when in standby.
Examples
With an 100Ah battery degraded to 90Ah we get the following battery lifetimes:
Always active: 90Ah / 1,07A ~3,5 days
Always standby: 90Ah / 0,48A ~7,8 days
13h active, 59h standby (Example from screenshot, total 3days): 13h * 1,07A + 59h *0,48A = 42Ah out of 90Ah (~50%)
Improved latency for BMA/BMC
We have been able to improve latency for the BMA working together with the BMC to < 1s. Measured by vehicle is physically present in a zone to the point when the BMC switches a dry contact.
Other Improvements
Fixed: On Curiosity startup the first Region of Interest event was always vacant (even if there were objects).
Improved: Curiosity performance improvements by avoiding to re-classify already classified objects
Improved: The Number Plate Column for DataAnalytics Parking widgets is optional
