While making the choices, you should be properly aware of what exactly they do and how do they differ, to start off let us have a look into DVR security systems.

Digital Video Recorder

The DVR replaced the previous model of multiplexer added with VCR. The previous model supported three hour long tapes with twenty five images per second while that playback had to be done through the multiplexer. With time and faster processors came along DVR which can record up to 480 IPS, the storage of thirty days can be turned to sixty or ninety as one desires. And this system brings the new feature of recording only when there is any motion in the place, called Video Motion Detector (VMD) and that saves up a lot of space creating a lesser load on the memory bank. With the pros of DVR security system comes the cons.Hard drives which might easily fail can compromise a bunch of important surveillance footage. The maximum resolutions offered by them remained around 640x480, which is VGA quality. The medium quality videos leave doubts about which can quite often be a dead end in an important point of the investigation in Chico, CA. DVR system is hard to update owing to the video cards, software and the operating system.

Network Video Recorder

The limitation in a DVR is that it compresses the live video feeds analogously while storing them on the memory disk. The NVR holds back digital images which are not yet compressed from the IP camera. The NVR is a better recorder than the DVR which at times can cause lapses. The NVR apart from being such a great recorder supports all video resolutions up to 1080p giving the users great view of what is happening. Being less expensive than the DVR systems due to the absence of cables, at the time the NVR system is preferred. The system provides great changeable memory disks. The systems come with a very user-friendly format and user interface and the touch screen feature adds to the user friendliness. Videos can be copied from the system to a personal hardware or PC for further investigation.

Which one to buy?

The NVR records better with a more stable connection which is through a network switch or router in other cases. The transmission process is one of the more striking features in the difference between the two. The NVR system provides the customers with better quality, better transmission, high definition videos and is less expensive than its only competitor in the Chico market. NVR is a more common choice among customers.

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."
