Section 15. Power Calculations and
Timings
The CC5MPX was specifically designed for operation in power-constrained
systems such as solar powered sites. It is critical in such systems that the
camera be properly configured to meet the constraints of the intended
application. This section outlines the power consumption of the camera for
purposes of power supply design for a system.
15.1 Standalone Operation
In standalone mode the camera operates as a self-contained image and video
logger. Files will be stored onto the internal SD memory card.
The current draw of the camera is mainly dictated by the quiescent current
draw of the Power mode plus the current draw when the camera enters the
Fully On power mode (Active Current Draw) to acquire an image or video.
TABLE 15-1. Power Consumption Table shows some total power
consumption figures in Amp-Hours per day depending on the Power Mode and
frequency of images.
One thing to note is that the Off State will only consume less power than the
Deep Sleep State if fewer than 24 Pictures are taken per day. This is due to the
boot-up time that the camera requires when exiting the OFF State. The extra
boot-up time means that the camera consumes the Active Current for a longer
time (120 seconds).
