"I used to work in the security industry. Once I got married and had kids I definitely wanted a home security system. Bought ADT about a month ago and it’s worked out excellent. No glitches or issues and everyone was awesome in the buying and activation process."

"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."

"Dave from reliant was super friendly and made the process very easy. He was also very knowledgeable on what I was looking for in a home security system and helped me determine exactly what I wanted. The install didnâ t take long at all and turned out looking great. Would definitely recommend giving Reliant a call."

"I initially hired SnapPro to upgrade my home theater with a new receiver and speakers but after some consulting I took the extra step and retrofitted my home with a Savant and UniFi system. Jordan was incredibly helpful in the selection of equipment and was able to answer my questions, regardless of how arcane I believed them to be. I am still amazed by all the features the Savant system is able to offer and how effortless it is to control my lights, window shades and listen to music in any of my rooms. My home has a new sense of luxury thanks to the folks at SnapPro."

Home Security Systems questions, answered by experts

Any type of dead bolt lock provides the highest level of safety for a single device. However, it’s also important to determine a lock's grade. Locks can come in either Grade 1, Grade 2, or Grade 3, which indicates how durable it is and if it’s constructed solidly. Safety experts recommend choosing locks based on Grade 1, which offers the highest level of durability.

Instead of a security door, you might opt for a heavy-duty screen door made from durable mesh, which allows better sunlight and airflow. Additionally, you could enhance security by installing strong locks on your existing door. A double-cylinder deadbolt provides robust security; however, be aware that some local laws prohibit them due to safety concerns during emergencies.

Hiring a professional ensures optimal camera placement, secure installation, and integration with existing security systems. Professionals ensure reliable operation and can offer system customization to suit specific security needs or preferences.

The best type of deadbolt depends on your specific needs. If accessibility is your primary concern, a single-cylinder deadbolt is the easiest to operate. Mortise locks are likely the most secure type of deadbolt you can install, but single-cylinders combined with secondary locking mechanisms like vertical locks are also a great option. Smart locks will give you the most flexibility to open and close your locks whenever and wherever you need to. 

While all security lighting systems offer different benefits, motion sensor security lights have the most advantages and the fewest cons for the average homeowner. While the upfront cost can be hefty, automatic, motion-detected activation will reduce your energy bills in the long run by ensuring the lights are only turned on when necessary. Plus, they’ll ward off intruders and help invited guests find their way onto your property in equal measure.
