']Re:] How to prevent light bulb theft in airport r'
Switch over to 220V light bulbs. Thieves won't come back when they find
the bulbs won't work at home. Probably only a few thieves.
Detecting burned out bulbs requires a monitor. Measuring current and
sounding alarm with each sudden drop may work for small number of bulbs per
circuit. Looking for 5% change (20 bulb string) is easy. Trying to detect
1% spike (100 bulbs) in environment with lightning, power surges, RFI.....
That could get challenging.
Except for expense, you could put a current monitor in each lamp fixture.
Poll each lamp via X-10 type communication.
That's it, I have to come up with a solution. On small airports, people
steal light bulbs from the runway. How to prevent (detect) it ? And maybe
detect burn-out bulbs as well ?
Thanks in advance.
