"With CH Tel. you get the right things done, the right way. I just moved into a house with no modern communications infrastructure. They gave us low voltage cabling, WiFi mesh network installation, security flood lights and cameras and doorbells. I now have computers on ethernet - so always strong faultless connections. And I'm ready to install smart TVs. The WiFi never drops and can handle all my devices from thermostats, garage door openers, flood lights, cameras, phones, TVs in any room, - you name it. The external cameras and flood lights give me better self-administered security than old fashioned monitored alarm systems. Cameras notify me if someone comes to the house, and I can check recordings to see what went on, especially when I gone. They hung a large TV on the family room wall and helped us mate the controllers. All this quickly done by friendly, expert techs working inside and out. So now we are back in modern times - easily. And ready for any updates coming down the road. Wish more companies were like this!"

"The RaLo electrician did a great job running new wire to install my outdoor camlight. He also informed me of a number of other issues he noticed and gave me good price to address those issues as well. I definitely recommend their services."

"I sent a request quote to Safe Streets and my phone was ringing within 1 minute. Impressed with the quick responsiveness. They are partnered with ADT which made our choice to get our alarm system through them a no brainer."

We would highly recommend Ultra Guard Security Systems for and work you need done whether you need an upgrade or a whole new system."

"Great service for installing home surveillance cameras. My technician, Lincoln, is very professional and patient and he worked with me to set up a good time to complete the install. He left the work site clean and made sure I knew how to view the cameras on my phone and laptop. He also took the time to explain the technical aspects of the camera system."
