(519) 346-6342 is the outgoing caller ID for the Security Response Centre, which is a monitoring station that monitors burglary/fire alarms all over Canada. This is a legit company! I work here!

Got a call at 6:50 am. Didn't answer. Annoying. Apt life doesn't need an alarm company.

Three calls in three weeks from this number at 1230am. Not happy. It is damar security in sarina, ontario. I am not on anyone's call list, so they shouldn't be calling me. I will report it and encourage everyone else to as well. More complaints equals action by the authorities...

They called me last night after 11pm and then again this morning.  Only they are calling my cell phone and not my house line.

They are trying to find out if your house has an alarm system.  They say "your alarm went off and we are calling to respond".  They are assuming your will say that your alarm didn't go off, or you don't have one.  BEWARE.  You might get robbed.

they just called me on my cell phone asking for my boyfriend, I told them that he wasnt present at the moment ... they identified themselves as DSRCalarmCo ... We do not own a house we are in an appartment building ... should i be worried.

Got the call at 7am, no answer, called back outgoing calls only does not accept incoming calls.

This is an Alarm Monitoring Station, when a property which you are a keyholder for has any troubles/alarms/events in which a keyholder is to be notified, they call you from this number. If you are a keyholder for your home, business, cottage, etc., the best advice is to answer the phone, there is an event that has occurred at a property in which you were to be notified. They do not leave messages normally unless requested to do so in their instructions, they continue down the Keyholder list until someone answers the phone.

I received a call from this number at 4AM. As one would expect, I didn't answer it.
I will now contact the police and report it.
