"I used to work in the security industry. Once I got married and had kids I definitely wanted a home security system. Bought ADT about a month ago and it’s worked out excellent. No glitches or issues and everyone was awesome in the buying and activation process."

Customers say: True professional

"William David Design (William Parr) recently installed a 77" TV, with a Motor-Assisted Vertical Travel TV Mount, on our stacked stone fireplace. He was recommended to us by a neighbor, and is now our Gold Standard. William initially gave us a detailed quote for the installation that we found reasonable and accepted. He gave us a timeline for his work and maintained it throughout his work. He patiently explained the operation of the entire system to my wife and me (both 80+ years old). He responded, both quickly and effectively, to all communications, was punctual, highly professional, knowledgeable and pleasant, and he completed his work in accordance with his quoted price (adjusted for a couple of small items we requested after he began his work). I unhesitatingly give William Parr my highest recommendation to anyone in need of the same or similar services."

"The space above our fireplace was just barely big enough to fit a 65" TV, but Ed mounted it securely onto the brick no problem. Such a nice guy, professional, and very fair on price. Originally I was looking at Geek Squad for mounting, but I'm much happier to support a local small business in stead."

"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

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.

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.

You likely can reset your house alarm without the code, but it depends on many factors like how it’s wired and whether or not there’s a default reset code. Most companies make bypassing a security alarm without entering your code challenging to prevent burglars from simply resetting the alarm during a break-in. Your best bet is to contact your alarm company directly to get specialized support for your situation. 

But, while you wait for support, you can disconnect it from the power source to stop the alarm from going off.

The cost of home automation averages around $1,000, with most projects falling between $200 and $2,000. The total cost depends on several factors, including the level of automation, brand, system features, home size, and location. For a DIY approach, basic home automation technology can cost between $100 and $500, though the scope and interaction between products may be limited. High-end, all-inclusive systems for larger homes can cost anywhere from $10,000 to $150,000, especially when they include smart appliances like refrigerators and dishwashers that require extensive wiring. Additional costs, such as subscriptions for maintenance services, can also impact the total price. It's often helpful to set a budget and consult with an expert to determine the best options for your home.

Technically, there isn't a difference between safe rooms and storm shelters. Both are designed to protect you from storms and extreme weather events. People often use “safe room” when discussing a shelter inside a building and storm shelter when talking about a detached unit. 

Additionally, a safe room is understood to have more functions than a storm shelter. You may seek shelter in a safe room when you believe an intruder is in the home or when under another type of threat.
