“My son had ADT in his house and he recommended it. My mother who lives with me is 102 years old and she keeps letting her cat in and out at night so I am unable to set the alarm during that time but I do when I go out. When my mother is going in and out, the system tells me that the door is opening or someone’s in the house. I appreciate that and it gives me a sense of security when I’m not at home. I have it for two and a half years now and it’s doing what I expect it to do. I’m very pleased and satisfied with the whole system. I would recommend it.”

“Gives me confidence that the premises is safe. The key chain fob is easy and convenient. Installer was polite and professional. I have used ADT for years but this new upgrade is wonderful and easy. The voice directions are concise and fully understandable.”

“Twice our friend and "cat-sitter" had inadvertently set off the emergency alarm and twice the police response was fast (arrived before she could figure out what she did wrong), professional, polite and reassuring. ADT followed up with phone calls. She was using the key fob. Just a suggestion: could the key fob be designed to reduce the amount of false alarms; e.g.: if the "panic button" needed to be hit twice in rapid succession to engage? That bright red emergency button, easy to see, is also easy to mistake if one is in a hurry and has her hands full! Thank you for great service!”

You have questions, we've got you covered
In Columbia, Maryland, do I need a permit to use an alarm?
Howard County says that all residents with professionally monitored alarm systems must sign up with the False Alarm Reduction Unit of the Howard County Police Department (Howard County). The first registration fee is $25 (one time), and renewals are free every two years. If you don't register, you could have to pay $200 for each police response. During your consultation, your ADT professional installation technician can help you with the registration process.
What will happen if my Columbia home has a false alarm?
Howard County gives out two false alarm warnings every year. The first false alarm costs $50, and the fines go up by $50 for each one after that, up to $1,000 (Howard County). ADT's Alarm Messenger™ feature helps cut down on false alarms. With alarm verification through Alarm Messenger™, ADT has seen over a 50% reduction in false alarm dispatches at sites enrolled in Alarm Messenger™ compared to sites not enrolled in Alarm Messenger™. Based on internal ADT data collected over the lifetime of Alarm Messenger™ (2021-current).
Does ADT put in security systems in Columbia condos and townhomes?
ADT can professionally install security systems in townhomes, condos, and single-family homes in Columbia's villages, such as Wilde Lake, Owen Brown, and Hickory Ridge. The village associations in Columbia may have rules about changes to the outside of buildings. Before you schedule the installation, check with your property management or village association to make sure it is allowed. ADT's technicians can set up wireless sensor options that don't require a lot of changes to the outside.
What places around Columbia does ADT work in?
The ADT Columbia team helps homeowners in Howard County and nearby areas, such as Ellicott City, Elkridge, Laurel, Jessup, Clarksville, and Fulton. Coverage also goes into the northern part of Anne Arundel County and the western part of Prince George's County.
How long does it take to install ADT in Columbia?
ADT installation times in Columbia may vary depending on how big the house is and how many devices need to be set up. The ADT Base, sensors, cameras, and full system setup through the ADT+ app are all part of the installation.
Does ADT keep an eye on things in the Columbia area during bad weather?
ADT's professional monitoring is available 24 hours a day, seven days a week, and covers Central Maryland's thunderstorm season and winter weather events. Water and temperature sensors can warn Columbia homeowners early about flooding or frozen pipes, which is a useful feature.
After I install my ADT system, can I add cameras or smart home devices to it?
ADT customers in Columbia can add cameras, smart locks, smart lighting, and more sensors to their ADT Smart Home System whenever they want after it is set up.
Do security systems in Maryland get lower insurance rates?
A lot of Maryland homeowners insurance companies will give you a discount if you have a security system that is professionally monitored. If you ask, your insurance company can get a copy of ADT's professional monitoring certificate. If a break-in happens while your system is being watched, ADT will also give you up to $500 in theft protection. Terms and conditions apply, see here for terms.
