Reasons to buy a home security system in Baltimore

Baltimore skyline

While Baltimore counts vibrant diversity, the Inner Harbor, Camden Yards and M&T Bank Stadium among its strong points, its persistent violent crime makes Baltimore one of the most dangerous cities in the United States.

Baltimore consistently ranks in the top five U.S. cities in terms of total violent crime, according to the FBI. It has a violent crime rate of 17.95 incidents per 100,000 residents and a property crime rate of 48.76 per 100,000 residents. This makes Charm City approximately 10 times more dangerous than the national average when it comes to violent crimes, such as murder and robbery.

DIY vs. professional alarm installation in Baltimore

In order to keep safe, Baltimore residents install home security systems. Professionally monitored home alarm systems often require installation by a company technician or a contractor, but do-it-yourself options are also available.

Professional installation is best for those without experience installing electrical appliances and for those who are not mechanically inclined. Additionally, because many of the city’s homes are brownstone structures like those in Mount Vernon, experienced installers will be able to better navigate any challenges during the installation process.

For DIY security systems, companies have helpful customer service reps on call to assist with guidance.

Home security permits and false alarm fees in Baltimore

Though these systems are voluntary, they are also regulated. Baltimore City and Baltimore County both have programs to reduce the number of false alarms, which divert police and fire resources away from actual emergencies.

In Baltimore City the permit is free, but failure to register your system results in a $100 fine, plus false alarm fees. In Baltimore County, the permit is free, but failure to register could result in significant penalties.

Baltimore City Baltimore County
Alarm permit registration No fee No fee
1st false alarm No fee in 365-day period No fee per calendar year
2nd $50 No fee
3rd $50 $50
4th $100 $50
5th $150 $75
6th $200 $100
