I received a couple of 20′ poles last week so thought i’d have another go at getting the dishes hooked up… I didn’t make any progress using "guess work" so decided I need to find a better way!

Getting on the roof the other end is going to be a bit tricky so I started at this end. Here’s a picture I took with my iPhone (remarkably good quality):

Zoomed to 100% of where I think I’m aiming:

I wanted to get a bit closer- so took this with my Canon 5D Mark II & Canon 70-200mm f2.8L IS @ 200mm @ 100%:

This is from google maps (you can see the other side of the two houses in the shot above- notice how close to the destination marker A they are):

Google maps again (this is looking roughly at the angle between the houses- it looks like I might just about miss the tree on the right hand side):

I’ve ordered a few cheap laser (lazer?) pointers from eBay which I hope to strap to the dishes for some further testing next week…

Watch this space!

I had a few minutes to continue setting up the wireless link and take a few snaps. Here’s the dish mounted:

And a bit of a close-up:

I found a better way of determining the bearing between the two properties using google earth (I had previously used googlecompass: https://tickett.wordpress.com/2012/02/15/setting-up-getting-started-with-ubiquiti-nanobridge-m5/):

Unfortunately I don’t really have any way of determining the dish’s current bearing (other than a visual guestimate). Google earth also shows the elevation profile:

Which seems to pretty much agree with the AirLink tool. Admittedly when I first used it I didn’t really know what I was looking at in the graph:

It surprises me the bearing isn’t displayed anywhere (that I can see?). I think I’m going to need a slightly longer pole to mount both the dishes giving sufficient clearance above the houses/trees in the path. I wonder what length I can get away with- the current pole is about 2 metres long and waves about quite a bit in the wind. I guess I just need something a little sturdier.

More soon :)

Home Security Cameras

I’ve been in the market for a while but couldn’t make a decision. Finally I thought I’d give the Ubiquiti Aircam a go: http://www.ubnt.com/airvision

Here you can see it mounted just below and to the left of the satellite dish:

And a bit closer up:

Quality isn’t amazing (1 megapixel) but price (£100), interface and ease of use make up for it:

I have another camera but have yet to mount it.

Currently the Aircam is running off of the included POE injector but I have ordered a few adapters to allow me to run them straight from my POE switch: http://www.ubnt.com/8023af

I have also ordered a Ubiquiti Unifi access point to try: http://www.ubnt.com/unifi and a pair of Nanobridge M (NB-5G25) combined bridge/antenna: http://www.ubnt.com/nanobridge with which I will attempt to create a link to a house "down the road".

*EDIT* As per request i’ve added a few bits.

Performance at night is pretty poor (no ir night mode) and i’ve got quite a bit of ambient light around. I intend to add a motion activated light in the back garden eventually though.

The web interface does work from my iPhone but it doesn’t look like it’s really designed to:

I’ve not noticed any options for text/e-mail alerts but once i get my hands on a raspberry pi and start using some form of central home automation software I will most definitely be looking at integrating it!
