Cerritos Weekly Crime Recap: July 11-July 17

The Sheriff's Pivot on was unable to report calls for service in the last summary, but data made available shows that there were 327 handled by sentry personnel the previous week, and that figure dropped to 280 last week. As they ran to stop the theft, one of the suspects produced a handgun and the workers backed off and allowed the suspects to lam out with the property. There was one robbery reported during this week. The  Los Angeles County Sheriff Department's Cerritos Train station  received 27 Part I felony reports of crime during this period.

How do I make a garage door monitor?

I wonder how to create a system that displays a light (or LED) inside my house whe the garage door is left open. I guess I need a sensor, an indicator and a power source. Need help with the details.


You can use a magnetic switch (located in the alarm section) from Sears, Home Depot or Lowe's. Run low voltage cable to your light and battery configuration. It works when the computer is off too!
