"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."

"Cinemaesque installed a TV and soundbar in our home. We had great customer service from the start. Doug was able to recommend and help purchase the TV and soundbar along with the necessary mounts and cables. They were able to fit us into their schedule quickly and were professional during the install. Finished product looks great and performs even better."

"They gave us the best rate and the setup was great for ADT system. The installer did have to tell us about other options that would cost more money but he did not pressure us when we declined. We had door, window and motion detectors included. They gave us a week to practice on the new system, but we could call if we were ready to go live sooner which we did. Set up was quick, easy and uneventful. Very nice installer, Phillip Brown. The cost was quoted at a low price, but the bill came from ADT and was much higher. We were told the contract to ADT did not catch up and we will be getting the lower price with a reimbursement for the excess of the first bill. We did the $99 install and are getting a $100 gift card back. 3 year contract is a little annoying but we plan to stay here for a long time."

Home Security Systems FAQs, answered by experts

Changing the alarm in your wireless security system is a perfectly reasonable DIY task that most people can complete on their own. Simply open the system’s control panel, remove the existing battery, and replace it with a new one. If you’re using a wired system, this may require disconnecting and reconnecting both the positive and negative wires attached to the battery, and you may want to call in a professional to help. 

It is possible to spend only $30 on a camera that can cover one particular area. You wouldn't need to buy software, hardware, cables, or anything else. Instead, it would connect wirelessly to an app on your phone where you could monitor the feed and take necessary actions at your own discretion.

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.

If you want to make more home security upgrades to your perimeter, consider installing a smart automatic gate opener and a security camera. These will allow you to see who’s at the gate and open it for them (or not). You can learn how to install an automatic gate opener yourself or hire a professional for a little extra.

Costs depend on system type, labor rates, and additional features like smart integration or professional monitoring.
