"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."

"Never finished the job. The handyman they sent was competent and hard-working, and the prices were reasonable, but working with the office staff to get him out to my home was difficult and unpleasant. My job was a 2-3 day job (partly because plaster needs time to cure, paint needs to dry, etc.), but they just wouldn't schedule him to finish it. The office staff were hostile and blamed me for their scheduling difficulties, as though I was the problem. They've cancelled their last two scheduled appointments at the last minute and are unable to give me any more dates."

"I had a full view glass storm door with sidelites installed in front of my Provia entry front door. The door is very sturdy such as thick heavy metal, lexan glass is clear, the hinges are smooth and strong, the lock is secure, the powder coated paint is beauty. the weather striping is robust and tightly sealed. The manufacturing process took a little longer than expected. A minor adjusted was needed for the lock. Medallion sent someone out immediately to solve the problem. My Provia Front entry door is awesome. I really wanted a full view security storm door to allow the Provia door to be on full display. In addition, to providing full security. Medallion knock it out of the park."

Home Security Systems questions, answered by experts

Yes, it's possible for hackers to access wireless security cameras by guessing or stealing passwords. Additionally, your camera's cloud content can also be hacked. Finally, some criminals use Wi-Fi signal jammers to disable wireless cameras.

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.

The cost of a home security system depends on the kinds of devices you install, but the average cost is about $750. Fully monitored systems with hardwired alarms, cameras, motion detectors, and lights will cost a lot more—up to $2,000. Meanwhile, a few wireless cameras that deliver video to an app will be significantly less expensive, starting at as little as $200.

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

Homeowners insurance can be voided in several scenarios. That can include making too many claims in a short period of time, leaving a home vacant for an extended period of time, renting out a home or room illegally, using a home as a business illegally, and any kind of criminal activity connected to the home.
