supervision of bee colonies

I have heard that there are existing some computers or notebooks for supervision of bee colonies. For the reason that I cannot find any information in internet (maybe because I do not know the exact name of such machinery), I am contacting this forum, hoping to get any information on this issue.
Many thanks to everyone!

What do you mean by bee supervision?
If it's beehive management, have a look at apitech.org They have an online application which helps you manage a beekeeper activity. All is in French.
If it's remote supervision, have a look at beewise.eu, they sell a remote weight measurement system (using SMS).
For anti-theft systems, beeguard.fr (gps+sms). Their system sends you an sms whenever the beehive is moved.
I do not use any of them, so I can't recommend them.
Regards,

Thanks for information!
Maybe You know also for other electronic systems when You can see not only the hive weight, but also (based on sound analysing system) You can see what proceses are happened in the hive on the moment - like nonbeing of a queen-bee or soon will be swarming...etc.
I have heared that such system are using beekeepers with more than 1000 colonies.

Hello karklinsj,

You will find information which you seek, on this page : www.bienenwaage.de/html/balance.html
(But you will have to translate the page into English language).
