"Bought security through ADT mainly for the automation options that come with the system. My spouse loves being able to turn on and off our lights in different areas of the house while we are gone. We travel often, so giving the illusion that we are home is a good deterrent."

"Workers left holes in eves after installing two exterior outlets for AC units, stepped through and into the ceiling, did not mention anything until I brought it to the supervising installers attention (repaired by Kent, no cost), installers left without confirming nor showing how to enable them outlets installed have no power."

"Cory did a very nice job for us. He took a look at our ethernet and WiFi network, and was able to diagnose our problems and make a couple of improvements. He was on-time, professional and easy to talk with. He was also very skilled in the technical aspects of modern networking. We often find that good local businesses like Wave Connects deliver solutions and services that are as good or better than the big companies. Cory and Wave Connects have proven this yet again. We will continue to call on Wave Connects for any other issues that we run into, and we will happily recommend them to friends and family."

Home Security Systems questions, answered by experts

DIY is possible for wireless cameras, but professionals ensure optimal angles, security integration, and network stability.

A deadbolt has a different design, construction, and security level than a regular lock. Regular locks are mostly used for interior doors around the home, like bedrooms and bathrooms, and they usually include a locking mechanism on the inside. While regular locks are easy to use and install, they provide little security. 

A deadbolt adds a layer of security and is most commonly used on exterior doors. The installation is typically more complicated, but they hold up to wear and tear.

Expect to spend an average of $150 to $500 to set up a home flood detection system. However, be aware that costs are wide-ranging. You might only spend a budget-friendly $50 to place basic, battery-operated sensors in a few key areas of your home, or $150 to set up two or three smart sensors. The purchase and professional installation of a whole-home protection system with water shutoff capabilities could cost between $500 and $1,000.

Any type of dead bolt lock provides the highest level of safety for a single device. However, it’s also important to determine a lock's grade. Locks can come in either Grade 1, Grade 2, or Grade 3, which indicates how durable it is and if it’s constructed solidly. Safety experts recommend choosing locks based on Grade 1, which offers the highest level of durability.

A security camera company will be able to advise you on where to position the cameras, ensure all of the equipment is set up properly, and do all of the installations. They’ll take factors into consideration that a non-professional might not automatically consider, like obstacles that could block a potential trespasser from the camera or how lighting may obstruct the view.
