"Bought security through ADT mainly for the automation options that come with the system. My spouse loves being able to turn on and off our lights in different areas of the house while we are gone. We travel often, so giving the illusion that we are home is a good deterrent."

"It can be hard to find people to work on your house that you can trust. Thatâ s why Iâ m so grateful to have found Chipman Electric! Travis and Tyler are locals and not only competent, but professional and experienced. They both provided outstanding customer service, gave me all my options before proceeding, and the quality of work was top tier. They installed 4 puck lights and 2 dimmer switches for me. They were able to jump off of an old ceiling fan that I had. I watched them work and it definitely wasnâ t a job I would have been cable of doing myself after watching. Great people, great work, would absolutely hire again (and plan to soon). You should too!"

"Dave contacted me and arranged to come out to my house the next day to check my dryer outlet. But much to my delight, he called me a short time later to say he was going to stop by now, as he knew I had out of town relatives that I was supposed to meet up with next day. He was able to get my dryer running and I had my day free to see my relatives! Great customer service!!"

Home Security Systems questions, answered by experts

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.

Home automation costs an average of $1,000, and most projects fall between $200 and $2,000. The total cost will depend largely on the level of automation you want in your home. High-tech, all-inclusive systems can cost well over $10,000 for larger homes, so most homeowners set a budget and then provide that to an expert to get the best results. You can also opt for DIY home automation technology for between $100 and $500, but the scope and interaction between products are usually limited.

Security cameras do not need wiring if they are wireless, meaning they are battery-operated and can connect through Wi-Fi. You’ll need to change the batteries on a wireless camera and ensure you have a steady connection to Wi-Fi for video storage. If you have a wired security camera, you’ll need to plug it into an outlet or other power source and a DVR device.

A keypad deadbolt, a lock requiring a code entered on a keypad entry, can be a convenient option for families with children coming in and out and needing access to the home. It can also offer an easy solution if you rent your home out, since you can easily change the code as needed. So, depending on your home entry’s needs, a keypad deadbolt may be worth the extra expense.

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.
