"We moved to Chevy Chase MD. I contacted three different security companies. By far Ultra Guard Security was the best. Andy was very knowable about security systems and not pushy at all. If looking for security system give them a call. You will be pleased."

"We like their service. We haven't had any problems. They are very good. This was the first time we've had an alarm/security system in our home. The supplier is ADT. I like that I can set my alarm every night before I go to bed."

"I communicated with Rob Calbo for services of a background check with CSI Secure Solutions and he was fantastic.
He spoke with me in a very professional manner and put me at ease right away.
The process was seamless and my request was delivered very efficiently. Within just a few hours of providing them with information, I was able to get feedback. Rob took the time to speak with me and answered all of my questions. 
I will definitely be using them again in the future should the need arise, and I would definitely recommend them as being very efficient, professional and reliable.

Home Security Systems questions, answered by experts

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).

Whether a security system or security cameras is a better choice for you depends on your needs and preferred comfort level. A security system can cost more depending on the features you choose, but it’s a more proactive and protective approach to home security by alerting you and authorities of any emergencies. Using a security camera system is a more reactive approach because while you can monitor the camera footage, it does not alert the proper authorities for you.

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. 

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.

Standard residential deadbolt locks come with a steel bolt that locks your door into place using a key (or keypad) on one side and a thumb turn on the other. When you lock it, the bolt slides into a strike plate on your door jamb to secure your door shut.
