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.
