Camera Location and Mounting

mcb1
mcb1
25 Aug 2013

This is part of my project to fit a solar powered RaspberryPi webcam at Mt Lyford that starts here

 

An excuse for a field trip (to a skifield) on a nice day, is not to be missed, however this trip was all business, with a couple of other things to look at/repair as well.

The exact location and mounting method was one of the things on my list.

 

Snow, ice and the odd heavy machine (groomer) means that unless its well anchored, its very likely to move.

Snow is a strange thing, and this year they received the largest dump in 30 years, over 2m (78 inches)

Many barns and sheds around the area, caved in with the weight of the fairly wet snow dump.

 

The snow was also delivered with high winds, which meant some drifts were 6m deep, and the only access to the field was by helicopter.

 

Obviously any mounting (and what its fitted to) needs to withstand some abuse, add in some brittleness from extreme and prolonged cold, and you need to plan carefully.

This pole is driven well into the ground and is solid.

It also is far enough away from the groomers when they shape the return track, as the corner is widest at that point.

 

The base of the pole has a nice area for a wooden battery box, that will withstand the elements (and the odd hit from a shovel ... if they need to dig it out).

 

The view from the location is right, and while this isn't from the RPi, gives the option of two tow lines to aim at.

(There has been very little additional snow and warm weather since that first dump, and as a conseqence a lot off trail has been lost.)

While I was there, I considered where the sun would be, and looked at what options there were for the solar panel.

This photo was taken at 12:46 pm and gives me a pretty good idea of the panel angle and orientation.

It can be combined with the other mount and will fit on the pole easily.

Because I couldn't ski that day, I had to borrow one of the new Snow mobiles, which I have to say are a bit addictive.

However it wasn't a joyride as I helped deliver some fuel to the rope tow ...

    Top bannana Mark love the photos..pitty you are 1/2/ the globe away I want to go up there just from the photos.

    Is this a comercial enterprise or purely for  your entertainment pr again a bit of both ??

     

    Just did a thermal Image sequence on a RPI thought that was cool but now fancy been out and about

    Thanks for the compliments.

    You get twice the NZ dollar for your pound, but you might want to wait until next year or more snow.image

     

    The field is commercial, and I started skiing there the year after they opened.

    The next year I got asked if I could fix their groomers drive card, and we've had a working relationship for 20+ years.

    I look after the electronics, and associated repairs, etc and in turn the family skis.

     

    Works out great for both.

     

    e14 were kind enought to supply the camera and the RPi, so its a win-win for everyone.

    Yes they (the Raspberry Pi) produce quite a bit of heat considering. However i'm not sure that even that is enough for up a mountain.

    Depending on the enclosure consider a few power resistors for heating and maybe some insulation and a fan for the summer.

    This is what the proper  security enclosures use.

    Mark I'm sure the enclosure part of getting it all working will be worth an article in it's self!

    Power is the consideration here.

    Having a couple of large resistors to warm it isn't in the power budget, and going to larger solar panels brings all sorts of other issues.

    Ensuring that the housing doesn't become a really big cold sink is one of the considerations, hence metal is out.

     

    Summer doesn't count ... there's no skiing, and the place is shut down.

    I think we will remove the installation during the shutdown period, mainly to stop it getting sandblasted.

     

    The skifield uses satellite to get its broadband connection.

    This serves the Ticketing office on line transactions, and the occasional web access.

    My intention is to WiFi it back to the office, where it gets processed and sent out every 15 mins along with the other two cameras to the website.

     

    cheers

    Mark

    Wonder if you insulate it with Glass wool or something the heat from the Pi would be kept in ?

     

    Any way have you also considered the 433Mhz Narrow Band RF modules that Farnell sell they are

    used by David ?? who does the high Altitude Balloon launches with the RPI
