"alarm company did not report the activation to police until 10 minutes after the alarm was tripped..."
So much for the service they provide.
Key takeaway here is TEST YOUR ALARM and don't assume speedy response.
Please disclose the name of the alarm company.

I thought APD was set up to receive alarms directly from the citizen alarm systems.

Menlo Voter, they are, but now they charge for it, so some residents figure they may as well pay for third party monitoring. What I find hard to process is thought most everyone is at home these days. How are break ins occurring in such a rampant fashion?

Thoughtful:

I have heard that many of the wealthy of Atherton have left town for one of their other homes that are more remote due to Covid. Don't know if it's true, but it's a possible explanation.
