Alarm Monitoring

Shearer Security Devices utilizes the services of AlarmWatch, located in Hunt Valley, Maryland, to monitor our Central Station accounts. Through the years, we have searched for a quality, professional contract Central Station. We have found that AlarmWatch has been virtually error free, courteous, and very flexible for those accounts that require procedures and requirements outside the norm. Having a separate Central Station insures that all signals that are sent are addressed… nothing is ignored. Erroneous signals must be addressed, not just “swept under the carpet”. Every detail must be correct.

AlarmWatch is UL Listed for Fire and Burglar protection System. They therefore must be staffed at all times, 24/7.  They have redundant power systems with back up generator and complete computer and security back up systems. They are housed in a “hardened facility” which protects their facility from any saboteurs and severe weather. Their high tech equipment assures accurate and timely response. Call backs to premises are found to be less than one minute.

AlarmWatch is far ahead of their league. AlarmWatch is one of very few Central Station Monitoring Centers in the world to have the capability of Voice over IP and networking alarm communications.

If you are paying more than $15.95 per month for security system monitoring - you are paying too much and need to contact Shearer Security Devices today.
