Best commercial electromagnetic locks according to redditors

Strictly speaking a door lock mechanism is a lock.

But OP is talking about a switch installed in something like your desk, which remotely triggers a magnetic lock on the door.

So you can lock your door while sitting at your desk, and no one outside can unlock the door.


Ever been to a store where they buzz you in? Think of the opposite. Those doors are always locked and the remote unlocks them.

So here is my take on this. You can do it pretty cheaply I would assume. You can buy a magnetic door lock like this one it comes with a wired buzzer. So if you wired an arduino with a wifi shield to the buzzer it will act as a switch that can be activated wirelessly, from a phone, cheap tablet, or computer.

As for the cameras I recommend some foscam outdoor cameras. They are cheap reliable easy to setup and can be viewed from phones tablets or computers. Good luck.

I bought the mag lock on amazon, only ran about $40. They have smaller ones with ~200lb holding force for around $20. 24v DC power supply was around $7 and 5v relay was around $6
