CCFC Field Camera
A-1
When the Wi-Fi is powered up and connected via an
Access Point (AP) or connected to an Existing
Network (see Section 12.8.2 Network), an extra 40
mA is added to the current power draw. When the
camera is transmitting large amounts of data (e.g.
when viewing live video), an extra 10 mA is added to
the power draw.
16.2 Operation with Communications
The power calculations are more complicated when
communications are involved, as the amount of time the camera is
in the Fully On active state is increased by the amount of time it
takes for the camera to transfer a photo or video.
The transfer times are influenced by two main factors: the size of
the photo or video and the transfer speed used to send the file.
The amount of time the camera is on will be increased as the size
of the file becomes larger or as the communication rate slows
down.
To properly determine the power consumption when using
communications, the additional time the camera consumes the
Fully On current draw needs to be accounted for in the power
calculation. Refer to Table 16-2 as a guideline for determining the
amount of time it takes to transfer files using RS-232 or RS-485
PakBus communications.
