"Andrew Brown from Alarm Protection Group facilitated the installation of our home security system. He was a very helpful and informative, and was not pushy, as with other ADT sales reps. He followed up with us after the system was installed to see if we had any questions or concerns re the system. I highly recommend Andrew to anyone who is interested in a home security system."

"I purchased a house with an existing security system. JR came out and was able to tell me exactly what I needed to update the system. During the installation the guys walked me through how to work everything. Very happy I went with DST Security."

"The owner of Electronics 9-1-1 installed an eight-camera home security system in my home. The entire experience, from initial consultation to finished product, was the model on which all other advertisers' services on Homeadvisor should be based! The company owner's recommendations about installation techniques, technical knowledge and considerations, equipment capabilities, scheduling accommodations, and modifications in mid-installation to overcome unforeseen issues were all spot-on, and resulted in a system that exceeded every expectation. Would use Electronics 9-1-1 again in a heartbeat, and it is a pleasure to recommend them to anyone needing security system installation or service of the highest quality."

Home Security Systems questions, answered by experts

In general, keyless door locks are considered safe, and their security depends on the type and quality of the lock. They cannot be picked like a traditional lock and often include added features like biometric access, PIN codes, and smartphone connectivity, which can make them more secure. However, they are not without risks. Potential vulnerabilities include hacking for Wi-Fi-connected models, battery failure, power outages, and technical malfunctions. To maximize security, it is important to choose a reliable brand, stay on top of software updates, and perform regular maintenance. While the risks are different, keyless locks are not considered more dangerous than traditional locks.

Expect to spend an average of $150 to $500 to set up a home flood detection system. However, be aware that costs are wide-ranging. You might only spend a budget-friendly $50 to place basic, battery-operated sensors in a few key areas of your home, or $150 to set up two or three smart sensors. The purchase and professional installation of a whole-home protection system with water shutoff capabilities could cost between $500 and $1,000.

You should always install cameras at exterior doors and windows. Other areas where you should place cameras are your front and back yards, the garage and driveway, common living areas, hallways and staircases, and the basement. Remember, you can start with a small Wi-Fi security camera system and always add more cameras if needed.

Yes, you should always change your locks after buying a house. Do so as soon as possible after you move in. Otherwise, you won’t know who has working keys to the property, whether they’re spare keys or otherwise. If an intruder gains access to your house with a key, it may not be covered under your homeowners insurance.

Installation typically takes 2-4 hours, depending on the number of components and wiring needs.
