Shortly after I leased my first office space in a local industrial compound, the in-house cleaning staff had an accident. One of the janitors which attended to that floor slipped on a wet tile and knocked my door clean off of its rusted hinges.
When I phoned my landlord, he advised me that it would take two weeks to repair the door. Since my office then was pretty much open to anyone, I made a decision to invest in a motion alert alarm to keep intruders away.
I procured a small, passive infrared alarm that was designed to monitor entryways and installed it facing the hole where my door used to be. My plan was to make use of it to alert the after-hours security guards to any possible trespassers.
The motion-detecting alarm would sound whenever somebody walks by it. And it could even be set up to perform a simple two-tone entry chime for when you’re at the office and don’t want the alarming to go off and call up the guards.
It was battery-powered, so that meant I could position it in any convenient location around my office doorway. I would not have worry about getting landlord approval to drill and run wires through the walls.
In the weeks that I had this security alarm, I turned on the two-tone chime while I was inside the office in order that I would know every time someone wanted to see me. I then switched it to alarm mode before I left for the day.
During this time, the security guards actually captured a few people attempting to sneak into my office in the after-hours. These were generally homeless bums off the street who were trying to steal anything that was not nailed down to sell it off for some quick money.
It seems silly to have to go 2 weeks without a door but I was able to improvise a clever solution using a motion alert alarm. Rather than throwing the thing away, I plan on keeping it and making use of it later on as part of a complete security system.
