"They were professional and delivered as promised. They removed the railing to replace the rusted part, welding a new piece to the existing railing. Then they reinstalled the railing. They strengthened the cement base of the second railing. Both railings were sanded and repainted. Our railings now look as good as new."

Home Security Systems questions, answered by experts

While a strong conventional deadbolt offers enough security for most homeowners, if you’re looking for extra features beyond just simple locking, smart deadbolts are the way to go. Smart deadbolts allow for keyless entry using your phone or a code, remote access in case someone is locked out, and features like temporary access codes, automatic locking, tamper alerts and entry-exit monitoring. Smart deadbolts also come with downsides: they rely on batteries and wireless networks and are potentially vulnerable to hacking by skilled home intruders.

In most cases, installing a driveway gate will improve the value of your home. Driveway gates appeal to homebuyers because they provide additional security for the home and make your property more private. Automatic driveway gates are extra convenient and will usually add more value than manual ones. The gate material will also affect the value addition to your home, as it plays a role in aesthetic appeal and security for your property.

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.

Thieves can open almost anything with enough time and the right tools, but they also prefer easy targets that are unlikely to get them caught. Forcing open gates is loud and difficult, and to be able to open one electronically requires extensive knowledge of the system, which most thieves don't have. Electric and other security gates are great deterrents because the thief will move to an easier target. If the thief is determined to enter your property, they will most likely find a different entrance point.

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.
