"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 would not hesitate to recommend MSI to anyone needing to have security cameras or alarms installed in their home. They always arrived at the time that was specified which was 0830. On their first attempt to install the cameras it was raining profusely but they tried to install them anyway. However, at one point it became to dangerous and they had to stop and reschedule the installment. Nigel Frazier and his team are very professional and knowledgeable about the security system that they install. I'm very pleased with their professionalism and reliability."

"I had issues with 2 lights and circuit breaker in my home and JA Electrical were a godsend. I heard back from them within minutes of placing online quotes in my area. I was able to get a tech, Antonio, out to my home the same day. He worked ho*** ** getting my issue resolved and he succeeded. He's very professional, timely, and I would highly recommend him and the company to anyone having issues."

"NWT was exactly what we needed. Our location was is a 120year old church, granite exterior, with both interior and exterior architectural restrictions that the normal installers I contacted did not want to proceed with. NWT has a great Facebook page that shows their previous work sites and that convinced me that they were the right contractor for us. NWT was not only able to provide us with the system we needed, but was able to do so within our budget restrictions. The crew was great to work with and their professionalism gave us the fit and finish I was looking for. If I had any questions or changes, they were only a phone call away. Their software specialist trained out staff in the operation of the multi-facetted system and is a call away if needed."

Home Security Systems FAQs, answered by experts

Insurance companies weigh the amount of potential liabilities on your property to increase (or decrease) the cost of your home insurance. They will use several factors to decide if there are more chances for peril or injury to take place at your home. These factors include your location (whether you live in an area with high risk for natural disasters), the age and condition of your home, and whether you have any “attractive nuisances”—features that both increase the aesthetic of your home and potential for injury—like a pool or treehouse. 

Yes, it’s possible a burglar can get through a deadbolt. Some types of deadbolts are harder for an intruder to get through, though. For example, a single-cylinder lock only requires breaking a window nearby and simply turning it. While other locks, such as a double-cylinder lock, may offer greater protection and make it harder for an intruder, no deadbolt is 100 percent effective.

A potential weak link in any security system is poor connection strength or dropped signals, particularly in the case of a fully wireless system. You also want to ensure a reliable connection to get a hold of your service provider quickly. Also, you should exercise caution when handing out sign-in credentials to people outside the household.

The benefit of deadbolt locks is that they're much harder to force open than simple locks with pin tumbler mechanisms, so they may offer added security. This feature is why many locksmiths recommend deadbolts for home security. For many households, this added protection and peace of mind is well worth the cost of installing a deadbolt.
