All of our installation technicians are internal employees, and not third-party contractors.

"The alarm, when it goes off, is very loud!!! This is a good thing. If we ever need to activate it, it will definitely scare off anyone trying to come into our home. We can set it off from our phone or from the keyboard control panel that we installed in our bedroom. We feel very safe with this purchase."

"I’ve had nothing but problems with SafeStreets. The installation was a mess—took hours longer than promised, and the technician seemed clueless about the system. When I called customer service, they were rude and unhelpful. The security system itself is glitchy and keeps going offline. Definitely not worth the hassle."

"We hired Martin Networking to install surveillance in our retail space. Jesse was professional and knowledgeable the entire way through the process. Prompt to our consultation, experienced with offering recommendations on placement of cameras and different styles available to give us the coverage we needed. The install was handled flawlessly. He was respectful of our space and kept all wiring concealed for a clean finish. After the install was complete, he made sure to follow up with a thorough explanation of the features of the cameras we selected and made sure we were comfortable accessing the app and adjusting settings to fit our needs. An additional trip was made for a minor adjustment on the angle of one camera and we have been very pleased with the performance of what was installed. So satisfied with service and product, we are having cameras installed at our home next. "

Home Security Systems questions, answered by experts

You'll likely need more than great home staging to sell your home. Now is a great time to get to work on the curb appeal of your home . Hire local exterior painters and landscapers to coat the exterior of your home and bring it new life with some sprucing up.

Various types of deadbolts are available, from the classic single-cylinder lock to a double-cylinder, rim deadbolt, smart deadbolt, and electronic deadbolt lock. Most homes in the U.S. use a single-cylinder deadbolt lock, which requires a key on the exterior and only a thumb turn on the interior to open or close the lock. 

Changing the alarm in your wireless security system is a perfectly reasonable DIY task that most people can complete on their own. Simply open the system’s control panel, remove the existing battery, and replace it with a new one. If you’re using a wired system, this may require disconnecting and reconnecting both the positive and negative wires attached to the battery, and you may want to call in a professional to help. 

Strike plates and security plates are the same thing, but there are strike plates that offer more security than others. For the highest security, look for plates made of heavy-duty steel, reinforced strike plates thicker than regular ones, and extended strike plates. It’s much harder to break into a door with these strike plates because they hold up better to force from attempted entry.

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.
