"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, most pros encourage you to change your locks when you move into a new home. While the previous owner may hand you their keys, you have no way of knowing whether other copies exist elsewhere. Changing your locks as soon as you move in is a great way to ensure that you can enjoy new, fully functioning locks that will work with your unique key or code.

Thieves can open almost anything with enough time and the right tools, but they also prefer easy targets that are unlikely to get them caught. Forcing open gates is loud and difficult, and to be able to open one electronically requires extensive knowledge of the system, which most thieves don't have. Electric and other security gates are great deterrents because the thief will move to an easier target. If the thief is determined to enter your property, they will most likely find a different entrance point.

Smart home upgrades can be worth the money. Several upgrades, including smart thermostats and ceiling fans, can help reduce your energy bills. Others make life more convenient, freeing up your time to do what you love (or get more work done). And some smart home upgrades, such as entertainment systems, simply make life more enjoyable. All are worthy causes.

Depending on your needs and wants, investing in a security door can be well worth the cost. Now that you know the pros and cons, you can decide if it’s a purchase that makes sense for your family. If you’re ready to have one installed in your home, look into security door installers in your area.

In general, daytime visibility for security cameras ranges from 10 to 70 feet. Higher-end cameras may have night vision that records 100 to 200 feet out. When shopping for any type of security camera, it's important to pay attention to focal length, resolution, and infrared technology to get an idea of the depth and crispness that will be used when capturing images.
