    Hi.

     

    Since this is for snap shot only ...... Power calculations are way out.

     

    Your looking at 1 hour of usage a day

     

     

    Actually there is only 6 minutes of "usage" per day.

    The camera takes about 30 seconds to take the snapshot and ftp the picture 12 times per day.

    The other 23 hours and 54 minutes its sitting IDLE.

     

    When idle its STILL drawing 170 milliamps. (around 2.38 Watts)

    The modem IDLE is 135 ma (around 1.89 Watts)

     

    Around 4.27 Watts CONSTANTLY (MINIMUM).

     

     

    Am I missing something???

    So at .180mA it's 2.16W which seems low for that camera, I get closer to 3W on my PoE switch but lets say that's true. Your modem is 1.5W. What is your power loss going for the panel voltage to charging voltage. I assume with a small panel, like a 100W panel the sell on Amazon for $150ish is putting out 18V and of course varies based on the sun. So there's a load to convert the voltage and charge the battery and typical battery losses. I would think a 100W panel with a decent battery should keep that camera going on sunny days, but what if it's cloudy/raining for a few days, what if it snows and covers the panel, that is if you get snow, what if you don't have the panel aimed perfectly at the sun. Keep in mind, a 100W panel may only put out max power during 2-3 hours per day, then it drops off, sort of looks like a bell curve and even then, it will never come close to putting out 100W unless you have a sun tracker to move the panels to face the sun.

     

    Thanks for the info @Buellwinkle

     

    I get 3 hours of peak sunlight Max (Atlantic Canada)

    My power calculations gave me 8 AMP HOURS per day.

    It said I need a 55W panel and a >55amphour battery.

     

    I currently have a 10W panel. Im upgrading:

    -> 55W PANEL

    -> 2 75 Amp Hour batteries.

    -> installing a Datalogger (controller) that will switch the power OFF over night and back ON in the morning.

     

    Pretty sure this should work right?

    Here are the results of the power draw test I did with a multimeter.

    Camera has IR turned off. Note the camera attempts to ftp a picture right away but is offline.

     

    A. Boot Up. -

    Lasts 30 seconds exactly.

    IR Stays ON during this period.

    Current Draw is 220 mA.

     

    B. Period between Bootup and Idle.

    IR Shuts off.

    power draw is 90-100 mA

    Last 10 seconds.

     

    C. Idle

    IR is Still off (as expected)

    power draw is 170 - 180 mA.

    Remains in this state.

    Where are you storing the footage, I assume you have factored that in too? A wireless router or computer will use extra power?

     

    I ftp a snapshot on the hour. its sent to a server.

     

    I am connecting to a battery which is powered by solar.

     

    Its also powering a modem but i have other sites that have a lot of other equipment so i need to break each device down seperately to make sure i have the right size panel (power calculation).

     

    It looks like nobody, even the manufactor, knows the exact draw while idle, and when sending via ftp, so what i will do is use an amp meter and try to figure it out on my own. i will post the results here. Will do late next week.

    Good Day.

     

    I am looking to install a Hikvision DS-2CD2032 3MP IR on a 12V battery and solar panel set up (using DC power not POE). Taking 12 snapshots per day on a 1 hour period. No IR and night time mode disabled.

     

    I am wondering about amperage power draw (amount of milliamps and duration)...

     

    On bootup.

    IDLE.

    While taking snapshot and

    etc

     

    or any other information that might be useful to me.

     

    I cannot find anything on this camera besides that its 5W max.

     

    Thanks in Advance.

    Im looking for a camera that can meet the following specs.

     

    1. Trigger it to take a < 100KB photo every 30 mins - 1 hour and send via ftp.

    2. Operational in cold temperature (-10C to - 40C)

    3. DC power from deep cycle battery (with solar panel)

    4. Compatible with 3 or 4 G Gateway modem (Airlink Raven x or 400Gx) for network connectivity.

    (note this means ethernet cable will be used to connect to modem so seperate means of powering is necessary - besides the POE since its using ethernet for the Modem)

    5. Configure Remotely

    6. Low power consumption < 5w (is ideal)

    7. Do not need vision

    8. cost < $450.00 CAD

     

    I have a Mobotix M12 which works well but is out of my price range for next installation.

     

    I was thinking to try the TRENDNET TV-IP302PI (Version v1.0R). At that price i guess it cant hurt.

     

    Any suggestions?
