"Ed was very professional. He did an excellent job at mounting our televisions we were so impressed with his work the first time we hired him that when we purchased our new home we rehired him to come and mount all of our TVs in that home. I highly recommend him to anyone."

Customers say: Super punctual

"Hey guys, I had an electrician from BriteBox, come to my house to investigate a problem I thought I had. As it turned he (Mark Henderson), the electrician pointed out while checking my electrical panel of something that could be gave down the road. We live in our homes oblivious to what lurks beneath the surface. It's almost, as if you need to take an electrician, along with you on your househunting endeavors. Too ensure the property you may buy is within code, certainly, if it's an older home! By the way he Mark, solved the problem with the original reason for the call!!"

Home Security Systems FAQs, answered by experts

There are a number of ways to secure windows. You can add motion detectors or window sensors to detect movement and impact or change the window locks to make them stronger. Some of the ways you can secure windows are much like how you secure a home: closing the curtains at night and setting up security cameras outside so you can monitor your property even in your absence. 

It's recommended that you have an upload speed of at least 10 megabits per second (Mpbs) in order to use a wireless security camera.

While security hubs can streamline the management of security cameras, the placement of cameras itself is often determined by factors like your property layout, security objectives, and areas of concern.

Yes, it’s possible a burglar can get through a deadbolt. Some types of deadbolts are harder for an intruder to get through, though. For example, a single-cylinder lock only requires breaking a window nearby and simply turning it. While other locks, such as a double-cylinder lock, may offer greater protection and make it harder for an intruder, no deadbolt is 100 percent effective.

If you're wondering what you should do with your old security alarm system after installing a new one, one option is to properly dispose of it at an electronics collection facility. Otherwise, if your old system is still in good shape, you can also donate it for someone else to use in their home.
