"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

The biggest downside to a wireless security camera is that it's 100% reliant on Wi-Fi to capture footage at your home. Even when Wi-Fi is reliable, the range for wireless cameras may only be 200 feet or less. Drywall, brick, and other materials in your home can be enough to make your signal lag.

Some but not all security cameras have monthly fees, depending on the specific camera system and the services offered with it, especially monitored vs. unmonitored security systems. Home security companies that offer monitoring services along with cameras will charge a monthly fee for monitoring and possibly for using the security cameras. Cameras that you monitor yourself as part of your own security system will not have monthly fees charged.

If you want to make more home security upgrades to your perimeter, consider installing a smart automatic gate opener and a security camera. These will allow you to see who’s at the gate and open it for them (or not). You can learn how to install an automatic gate opener yourself or hire a professional for a little extra.

While many security cameras are internet-connected, not all require a constant connection. Some wireless options operate independently of the internet, providing essential security functions even offline. They typically have features like local storage capabilities, like microSD cards or network-attached storage (NAS), which can still record footage even when Wi-Fi is unavailable. The camera-stored data can be accessed later once the Wi-Fi connection is restored.

Yes, you can install a home security system in an old house. In fact, you can install a security system in any home. Some wiring may need to be added, but most home security systems do not require a lot of additional wiring. Wireless security systems can easily be installed with minimal additional wiring, if any at all. Most wireless security systems can be monitored and controlled from your smartphone, and the cameras and sensors operate on batteries.
