"My company has an offsite warehouse way out in the country about 15 miles from our main office. We wanted to add surveillance at the warehouse so we don’t have to go out there to check on things as often. We purchased an adt camera package and it has really helped cut down on our travel time. Simple but effective way to add surveillance to our storage warehouse."

Home Security Systems questions, answered by experts

A deadbolt is one of the most secure locks you can install on your front door, so it is better in terms of home security than other types of locks. While deadbolts are typically more expensive than a regular lock, they’re still quite cost-effective and provide an additional layer of security that may even deter some intruders.

Window security film won’t prevent break-ins or stop your window from shattering from impact during extreme weather like hurricanes or tornadoes. However, applying security film is relatively inexpensive, and it can make breaking into your home significantly harder—often hard enough to deter burglars entirely—and keep your window from shattering on your floor after impact. For these reasons, window security film is often a worthwhile investment that helps protect your property.

Various types of deadbolts are available, from the classic single-cylinder lock to a double-cylinder, rim deadbolt, smart deadbolt, and electronic deadbolt lock. Most homes in the U.S. use a single-cylinder deadbolt lock, which requires a key on the exterior and only a thumb turn on the interior to open or close the lock. 

Standard residential deadbolt locks come with a steel bolt that locks your door into place using a key (or keypad) on one side and a thumb turn on the other. When you lock it, the bolt slides into a strike plate on your door jamb to secure your door shut.

Instead of a security door, you might opt for a heavy-duty screen door made from durable mesh, which allows better sunlight and airflow. Additionally, you could enhance security by installing strong locks on your existing door. A double-cylinder deadbolt provides robust security; however, be aware that some local laws prohibit them due to safety concerns during emergencies.
