Door Monitoring and Control with Internet CCTV, Part 1

January 4th, 2021

Because internet CCTV cameras are intelligent, as opposed to the “dumb” traditional CCTV cameras, you can use them to see your property from wherever you are in the world, over the internet.  That, however, is just the start.  By joining these cameras to simple alarm and control circuits, they can be used to monitor and control doors. 

Seeing your home, business, or family from the other side of the world is amazing enough, but wireless internet CCTV cameras can do so much more than even this impressive feat.  Most of the best of this type of camera that your provider offers in Chico, CA will have a digital input/output port, or I/O port, that allows the camera to be connected to electrical circuits.  The two input connectors on the port can be used to monitor an alarm circuit and trigger an alarm as I will explain.

The input connectors can be wired to each end of a so-called alarm circuit that in reality is nothing more than an unbroken loop of low-voltage wire, connected to, say, a pair of magnetic door contacts.  These are a standard part of any alarm system, but for those of you who have not come across them, you basically get two magnets, with plastic mounts.  One of them has connectors for the two wires of the alarm circuit.  You screw this one with the wires to the door frame, and the other one to the opening door so that they are lined up very close to each other when the door is closed, which keeps the circuit unbroken.  This is known as a “normally closed” or “NC” circuit because in its normal state, the circuit is complete or closed.  When the door is opened, the magnetic contacts separate and the circuit is broken.

The wireless internet CCTV camera will detect when the circuit is broken because there will be a change in voltage at the input connectors and the camera is programmed to raise the alarm when this happens.  So, when the door is opened your camera can send an immediate message across the internet to a central computer.  This computer is programmed to send a text message to your mobile phone, and perhaps an email too – all within seconds of the door being opened.  Of course, if you want this great feature without “getting your hands dirty”, you will need a specialist “internet CCTV” company that can provide you with a camera pack ready-configured to work with your alarm circuit, so you can just plug it in. Contact your local provider in Chico, CA to learn more.

What Our Customers Say

"I had the Alibi system installed several years ago. It has functioned flawlessly. The image quality is exellent both night and day and in all weather conditions. I particularly like the replay (which can be set at various speeds) and zoom functions of the system. Tech support from Crimefreeliving has been excellent. I have received quick responses to questions, and timely home visits — as when I changed IP carriers and my Alibi system needed to be reset. I have recommended Crimefreeliving to several friends."


"As a small business owner here in Chico we definitely saw the need for video surveillance. After expressing our needs and concerns Tim did an excellent job getting us set up with the set up with the appropriate equipment. He really took the time to address our concerns in a very friendly, professional and knowledgeable manner. I highly recommend Tim for all of your business and residential video surveillance needs."

Ron H., Owner/Auto Doctor

"I have to say I love having my security cameras at my home. Tim Truby did a wonderful job of installing the five cameras. He is very neat and cleaned everything up after the installation. He explained to me how to operate the monitor, my phone and IPad. However, I have had to call Tim because I'm not tech savvy and forget what he has told me. He usually just helps me over the phone and then all is well. I'm 80 years old and enjoy the comfort of knowing I have these security cameras."


"Tim Truby designed and installed a 32 camera system for us here at the Butte County Mosquito and Vector Control District. We had received several other quotes from security system vendors, but Tim’s quote was the least expensive. Tim also installed the system quickly and has always been available when we needed him. We are very happy with our security camera system and we can highly recommend Tim Truby for all of your surveillance system needs."

D. Weseman, Butte County Mosquito and Vector Control District

Crime Free Living updated our old video system with a new 16 Channel HD Alibi Video Security System. The old system had been added onto by different installers which resulted in a cabling mess. There were cables that worked and cables that went nowhere. It was a mess. Tim sorted it all out and installed cameras that are very clear. He also installed a monitor for our cashiers to watch hidden areas, a monitor to watch the entry door, and a monitor that allows employees to watch the outside parking and gas pump area. All work was done on time and very professional! Will always recommend Tim and Crime Free Living.

S. AM PM Chico Arco Station

"I had Tim install an Alibi Video Security System at my residence and a couple business locations. The remote view option is invaluable to absentee owners or anyone who travels a lot. The clarity and quality of the cameras have allowed for viewing employee theft. The evidence provided from the HD video cameras was fantastic! Tim was professional and provided extra value from his law enforcement background."

J. Folsom Arco Station

"Tim, I want to thank you again for doing such a fantastic job on installing a wireless IP security camera system at our dream home. The extra time that you took to hide wires, and install a clean, professional system is much appreciated. I still can’t believe the clarity, quality, and ease of use of this new system. I wished that I would have met you before our original inferior system was installed by another company. Now, whether I am at home, or monitoring the system from around the world, I know that my home and family are safe and sound."

John M.

"In April of 2017, my husband and I made a phone call to Crime Free Living that turned out to be a smart and wise decision. Amazingly, in just a few hours, Tim installed four Dome Security Cameras, weatherproof enclosures, and hooked up into our home a 23" Full HD Widescreen Security Monitor. Even more than his professional expertise was the time spent with us in making sure that this system was working correctly and properly installed on our phones so that anywhere in our travels we can monitor our new home in Magalia."

Tieka and Don S.

"I have been using Crime Free Living for the last couple years ar work and at home and I really recommend this product. Tim is a very good service provider. If he can't figure it out, he's got good tech support with the system that he offers."

Gary D.

"I have known Tim for over 10 years. To date, Time with Crime Free Living has installed two separate surveillance systems for my company. With each system, Tim has listened to my needs and custom dsigned surveillance systems for my specific needs and within my budget. The equipment used is always state of the art, the workmanship is top notch, and Tim is the example of trustworthy. I would recommend him for any job."
