1   General Information

The CARRIDA Dragon cameras have been designed for high resolution image processing with a very small form factor. They are the ideal compromise between high performance and low system costs.

Based on a quad-core processor ARM® Cortex®-A53 with 1.2 GHz the CARRIDA Dragon cameras offer ANPR solutions at high-speed in real-time.

All cameras are equipped with a battery backed real time clock and come with several programmable input/output signals, with trigger input and flash trigger output, as well as a 100 MBit Ethernet interface. Different CMOS sensors with global shutter are available (the image resolution can be changed to the ROI required).

2.1.2   Electrical Specification: Camera Power Supply

Voltage/Current Overview
Nominal Voltage 24 V
Nominal Power Consumption [1] 7.5 W
Minimum operational voltage (including ripple) 9 V
Minimum nominal Operating voltage and corresponding current 12 V, 625 mA [2]
Maximum nominal Operating voltage and corresponding current 24 V, 312 mA [2]
Maximum operational Voltage (including ripple) 30 V

Power must be connected to pin 1&2 of the ST 1 connector.

Camera power is regulated, so only an unregulated power source of 12 V to 24 V is required. The camera is, however, very sensitive to power supply interruption. Please make sure that the voltage never exceeds the limits of < 9 V, > 30 V even for a short period of time.

Note that the LED IR illumination of the camera may not be operational at a power supply <24 V.

2.3   Realtime clock and backup battery

The board contains a realtime clock (RTC) with battery backup. The RTC is set during manufacturing to the current date and time. For backup a rechargeable lithium coin cell battery is used. This battery is charged to only about 10 percent of the nominal capacity on delivery and may be empty after a prolonged period of storage. We recommend charging the battery for at least 50 hours and setting the RTC (Linux command: hwclock and date) when the board is first used (battery charges automatically when the system is powered on). The battery contains so little lithium, that it is not listed as a hazardous device for the environment and the flight export regulations. For details please refer to

Backup Battery Specifications
Battery Manufacturer Panasonic
Battery Type ML621
Nominal Voltage 3V
Nominal Capacity 5 mAh
Charging Time for 100% Capacity 100h
Charging Time for 80% Capacity 50h
Backup Retention Time for 100% Charged Battery 200 days


Note Sign

To check if the hardware clock is set appropriately, scan the output of the following linux shell command:

dmesg | grep rtc

One response line may contain the following message:

[ 0.322074] rtc-ds1374 0-0068: oscillator discontinuity flagged, time unreliable

This indicates low battery status or battery discontinuity.

To set the hardware clock it is necessary to set the software clock first:

date -s "2017-11-21 11:47:00"

Then the software clock time is transferred to the realtime clock by the following command:

hwclock -w

2.4   Built-in heater

The CARRIDA Dragon camera contains a built-in heater which is automatically activated when necessary. The following table and diagram show the behavior of the heater.

Temperature Heating power CPU
T < -5 °C 100 % (23 W) Off
-5 °C < T < 5 °C 20 % (4.6 W) On
T > 5 °C 0 % On
