Wide Dynamic Range Feature in Security Cameras

May 7th, 2021

Wide Dynamic Range (WDR) is a feature that has been heavily employed in the Chico, CA video surveillance industry, and its main work is to boost resolutions of images recorded by security cameras. WDR can be explained as the camera's ability to clearly distinct contrasting levels of brightness, and that aspect is important since excessive brightness such as overly sunny conditions can obscure some important image details. This feature makes it possible for clear images to be obtained when a certain premise area may be under very bright illumination or very dark areas that are concurrent with FOV. WDR functionality ensures that all the intense lighting that may be surrounding an object are isolated so that it can be possible to accurately distinguish between the shapes and features that may be observed in an image. This WDR feature is very relevant since many criminals in Chico, CA often take advantage of dark areas in a premise with the hopes that poor images may be recorded by cameras under such conditions.

Many security camera systems don't have WDR in the default setting, though it is important for this feature to be ever functioning. Anytime WDR functionality is activated, a security camera system can respond with vibrant images in any Field of View (FOV). Some premise owners may see 1080p images as very brilliant, however, if WDR is added to that an already amazing quality, the result is often clear, brilliant and high-resolution images that have good contrast. That aspect will eliminate the chances of encountering blurred images that cannot effectively lead to any meaningful direction when important security analysis is done on images recorded by a security camera.

Security surveillance videos have certain lighting conditions that are hard to control, and that means a lot of care must be exercised when picking a camera that can adequately cover all critical and selected Field of Views (FOV) in Chico, CA. In many video security applications, there are often areas that show contrasting brightness and cannot be effectively monitored by the standard non-WDR security surveillance cameras. For instance, if you installed a 1080p security camera in a parking lot, you may have overly bright images with lots of flashes that can lead to poor results when an analysis is done on them.

If your security camera system in Chico, CA doesn't have WDR feature, you can opt for digital WDR enhancement. Digital WDR utilizes a software functionality that aims at improving image quality by adjusting the gamma values with the intent of enhancing the clarity of the dark image areas. Meanwhile, it is important to note that the outcomes of true WDR cannot be compared to that of software WDR. True WDR employs a double exposure principle that picks on the longer exposure time to get accurate details of the dark image areas. Another exposure is taken with the shorter exposure time so that the details of the bright image areas can be processed right. The convenience offered by WDR functionality makes this feature a must-have on any security camera installation, and it should be a major requirement for any security camera.

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."
