Section 7. Camera Operation Using Web Browser Interface
7-25
One of the main factors in determining which power mode to use is the power
consumption budget that is available for the camera.
If the camera is operating from an AC main power supply, then the camera will
have the best performance characteristics in the Fully On State. On the other
hand if the camera needs to operate from a battery for long periods of time,
then the OFF state will be more suitable.
TABLE 7-4 outlines the operational characteristics of each power mode.
TABLE 7-5 shows typical response times from when a trigger occurs to the
time that a picture or video is taken. The OFF state takes the most time as the
Main processor is not powered on in this state and it must completely boot up
to operate again from the OFF state.
TABLE 7-4. Power Modes
Power Mode Ethernet
Power Save Mode Operating Characteristics
Always On
• Camera is always on
• Highest Power Consumption
• Ethernet is on and always available for incoming communications.
Moderate Power Save
Mode
• Not recommended
Fully On
Full Power Save Mode
• Camera is always on.
• Average power consumption is reduced by 50mA @12VDC
• The Ethernet is normally turned off and is only enabled when
outgoing communications are required (Email or FTP).
• User needs to push the Setup button to temporarily enable the
Ethernet port for Web page access.
Always On
• The camera is effectively off in a low powered state.
• Typical Power consumption is 80mA @12VDC
• Ethernet is on and always available for incoming communications.
• The camera will temporarily wake up to the fully on power mode
when traffic occurs on the network. In situation where there is
constant network traffic then the camera may effectively be in the
fully On Power mode.
Moderate Power Save
Mode
• The camera is effectively off in a low powered state.
• Typical Power consumption is 80mA @12VDC
• Ethernet is always off.
• Disconnecting and connecting the camera to another Ethernet
device will momentarily wake up the camera to allow it to process
incoming communications. The camera will go into the low
powered mode again if no communications occur.
Partially On
Full Power Save Mode
• The camera is effectively off in a low powered state.
• Average Power consumption is typically 10 mA @ 12VDC.
• The Ethernet is normally turned off and is only enabled when
outgoing communications are required (Email or FTP).
• User needs to push the Setup button to temporarily enable the
camera and Ethernet port for Web page access.
• The camera can respond to RS-232 and RS-485 communications in
this mode.
