"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

Yes, you should always change your locks after buying a house. Do so as soon as possible after you move in. Otherwise, you won’t know who has working keys to the property, whether they’re spare keys or otherwise. If an intruder gains access to your house with a key, it may not be covered under your homeowners insurance.

The average cost to install a home security system is about $750. However, the price can range from as little as $200 for a simple wireless camera setup to $2,000 for a fully monitored, hardwired system. A typical price range is $280 to $1,150. Several factors determine the final cost, including the type of system, equipment, materials, labor, activation fees, monthly surveillance fees, and permits. Optional upgrades will also add to the price, such as video surveillance monitoring ($40–$65 per month), smart locks ($150), smart lighting ($15–$90), smart smoke and carbon monoxide alarms ($35–$100), and a smart thermostat ($130–$500).

The best window alarm sensor depends on the type of window you’re concerned about since different types of sensors will work best in different scenarios. Many homes are equipped with contact sensors, which trigger an alarm when a window is opened, and each part of the sensor breaks contact with the other. But there are other options, too, like a glass break sensor or motion sensor, which both work well for windows that are in low-traffic areas.

To prevent false alarms, motion detectors need proper placement and settings. Start by installing them away from pets and windows where outside movement could set them off. Adjust the sensitivity settings to reduce the likelihood of it detecting minor motions. Consider using dual-tech sensors, for example passive infrared (PIR) and microwave technology, to improve accuracy and reduce false alarms. And don’t forget regular maintenance—cleaning the sensor and checking for any obstructions can go a long way in making sure your detectors run smoothly.

Yes, many providers offer remote troubleshooting and monitoring for business networks.
