Remote switching?

[The Dentist]

Hi Fellas

I have a project on to reduce power consumption, and currently have outdoor son lighting which is controlled via a photocell, and I am adding a timer so that they can be off all night on a saturday (no night shift on sat) but the on site security would like the option to be able to switch on the lights if they need to

The switching is not a problem as I can use a contactor to operate the lighting contactors bypassing the timer, but as the distance from where the security office is to the lighting contactors is about 600 meters, I dont fancy laying cables all that distance, not to mention the cost

So I'm looking for some kind of radio controlled switch and receiving unit with a latching/unlatching relay which will be capable of this sort of distance? Any ideas?

Many thanks

does it need to be radio?

you can probably do it with a PLC connected to a telephone with the right software in it..

you can buy remote power switches ready built for use in server racks etc where out of hours resets etc may be needed by the client / IT guys but these run into a couple of hundred quid..

or there's this... http://www.lightingforgardens.com/rkmain.asp?PAGEID=36336&stk_prod_Code=LS3SKIT&ctl_cat_Code=

Love the link, "1Km range with the ability to extend"...... could switch the lights on at home from the comfort of the pub

with the right bit of hardware and the right phone app you can switch your lights ( or almost anything else in the house ) from Sydney if you wanted..

There must be an app for this

Go IP and you can control from anywhere in the world.
