Which Analog Camera Retrofit Solution Is Right for You?

June 10th, 2021

Previously, offering video quality in Chico, CA was only possible with IP security cameras. Today, HD over coax has transformed surveillance options. HD over coax provides you the benefits of both the modern HD IP camera technologies and older coaxial technologies. If you cannot find an IP camera solution that meets your needs for long distance surveillance setup, or you are planning to update your old CCTV or coaxial based surveillance systems, choosing an HD over coax solutions makes the upgrade more efficient and attractive. Here are some of the essential details you should know about HD over coax solutions.

Basic Info about HD over Coax Installation

If you are using 75-5 or 75-3 coaxial cable, chances are that your existing cabling in Chico, CA can work with the new HD over coax technology. HD over coax cameras retail all details similar to IP camera solutions by composing videos, audio and data signals and transmitting them digitally to an HD over coax DVR. IP cameras use compression before transmitting enabling video processing and optimization in the DVR on the receiving end.

Types of HD over Coax Technology

HD over coax solutions handle transmission and decoding differently. The four major classifications of HD over coax technology include:





Even if similar lenses, wiring and sensors are used, each of these technologies will produce different results. What may appear distorted or washed out in one technology might look smooth and crisp on another. Most solutions require the DVRs and Cameras to use the same HD over coax standard to operate optimally. To ensure maximum savings as well as benefits, you choose the right HD over coax technology. After thorough research in Chico, CA, it was found that the EX-SDI technology outperforms the others.

The Best HD over Coax Technology: EX-SDI

The EX-SDI solution uses a standard RG59 cabling that is present in most analog surveillance systems. It transmits clear 1080p videos more than 1,000 feet. If RG11 is used, this distance multiplies providing resolutions of up to 4k.

The signal of the EX-SDI solution is less vulnerable to external noises and interference. Flawed cables, electrical circuitry, lighting and ground loops are not a concern with this HD over coax solution. After capturing footage, the EX-SDI streams it to DVR uncompressed. Once in the DVR it is then compressed and optimized for storage. Stored footage can easily be reviewed by determining the time you want to view and hitting the play button.

EX-SDI solutions come with a perfect light compensation and attractive colors. It is not prone to overexposing images due to inconsistent lighting. In addition, it can handle wide dynamic range video footages without issues. It performs equally well in low light conditions, as long as the right cameras are installed. Images are clear with no artifacts or image noise while the color is well retained at fat lower lux levels.

Whether you are looking to upgrade your old surveillance system or you just want to design a new system for a company in Chico, CA, an HD over coax will help you reduce the costs while providing the protection you need. Call us today to help you design and install your new HD over coax solution.

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."
