"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 HIGHLY recommend Jon and Dena. Their customer service throughout the process (consultation and installation) was stellar! They are very warm and understanding people who do not try to sell you on extra products. The men (Phil & Josh) that came to install the security system were prompt, professional and nice. They were very knowledgeable and TRUST WORTHY! I never write reviews but for this type of service and care, I had to come leave a comment about my experience with security and alert Corp. Iâ m very happy with the work done and how it was done! Thank you!"

Home Security Systems FAQs, answered by experts

Leaving a light on at night probably does not deter burglars as much as we would like. While there isn’t much evidence supporting the theory that lights deter burglars, there’s not anything disproving it either. If you feel like it offers added security because a burglar thinks you’re at home, then you can set your lights to a timer so they go off and on at intervals, mimicking someone moving around inside the house at night. A better idea is to install motion sensor lights in your yard.

Keyless locks are great for convenience, letting you unlock doors with a code or your phone so you don't need to carry keys around. They also often come with helpful features like temporary codes for guests. On the downside, they can be more costly up front and do require batteries that will eventually need replacing. If you value ease of use and additional security features, keyless locks are worth the investment.

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.

The average cost to install a home security system is about $750. However, the price can range from as little as $200 for a simple wireless camera setup to $2,000 for a fully monitored, hardwired system. A typical price range is $280 to $1,150. Several factors determine the final cost, including the type of system, equipment, materials, labor, activation fees, monthly surveillance fees, and permits. Optional upgrades will also add to the price, such as video surveillance monitoring ($40–$65 per month), smart locks ($150), smart lighting ($15–$90), smart smoke and carbon monoxide alarms ($35–$100), and a smart thermostat ($130–$500).

Your best bet is to install a bracket that secures to the bottom of the unit and the side of your house. You should still secure the AC unit in the open window using some of the other methods already listed, but a bracket is best to ensure that it stays put—both during operation and in case of an attempted theft.
