15.4 PakBus Neighbouring Address
The PakBus protocol allows devices to relay data in a network. The CCFC has
the ability to communicate with devices that are several hops away on the
PakBus network. To configure this new feature, a setting has been added to the
PakBus configuration screen on the web page.
Physically entering the address of the PakBus device connected to the CCFC
PakBus communication lines allows the neighbor to relay communication
between the CCFC and the final destination for data. Leave PakBus set to zero
(0) if the CCFC is directly connected to the final destination.
16. Power Calculations and Timings
The CCFC was specifically designed for operation in power-contrained
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.
16.1 Standalone Operation
In standalone mode, the camera operates as a self-contained photo and video
recorder. Files will be stored onto the internal camera memory.
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 a photo or video.
Table 16-1 shows some total power consumption (standalone) figures in Amp-
Hours per day depending on the
Power Mode and frequency of photos.
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).
