Large Format High Definition Flatscreen Monitors May Not Be the Best for Security Monitoring

Before you go out and buy one of those impressive 42" high definition monitors so your CA customers know you have a first class security system monitoring your premises, think again. Large format HD monitors are able to deliver spectacular imagery, and with prices going down, they are quite popular. However, before you expend close to a thousand dollars on an impressive means of displaying your CCTV cameras, look at the facts.

Multiplexers, the devices that allow images from numerous cameras to be displayed on a single monitor, do not have high definition output. It is inevitable that this will change. But as of this writing, mulitplexers such as Bosch's LTC2682/90 and Pelco's Genex multiplexers that will allow up to 16 cameras to be displayed on one screen do not have the capability to display these images with enough resolution on a large screen. It is best to stay with a 20" screen, more or less, for the best viewing quality.

If you wish, you can drive a large format flatscreen monitor through the VGA out port on a DVR. The VGA output provides a reasonably decent image on up to a 32" screen. Any screen size larger, and the image starts to degrade. Another downside to having to drive the large format monitor from the VGA port of a DVR is that the screen becomes the monitor for the DVR's configurations and maintenance. Most DVRs have at least one separate monitor output that only passes the video images through. Using the VGA output should not be used for a public monitor unless you want everyone to be able to see a technician working on the configuration settings, or a manager reviewing video of a theft in , CA. Of course, a video switch can be used to turn off the public monitor while work is being done on the DVR, but it's certainly not the best solution.

What is the best answer? Keeping in mind that CCTV monitors are specifically designed to receive the video signal from cameras, they should have at least one BNC input. So far, the large format HD monitors are not designed to CCTV specifications. As with most electronic technology, it's best to wait for high definition outputs on DVRs and multiplexers, designed for large HD screen sizes. A few are becoming available, like the Samsung STM-42L, but it's expensive at $3500. This writer will remain skeptical until he's seen it tested. In the meantime, use a 19" LCD flatscreen, or slightly larger, and if you need to keep 16 or more images viewable in a large enough window to provide monitoring, sequence the images using settings within the DVR or multiplexer. Use quads, if the images need to remain visible. The quad multiplexers split up to 4 cameras' views onto one monitor, and they are one-fourth the cost of a larger multiplexer. Then use as many monitors as necessary to display all the cameras.

For the time being, it is best to continue using smaller screen sizes for monitoring security cameras in , CA. But it won't be very long before the prices come down on the large security camera monitors: notice how HDTVs have dropped recently. Of course, if you have more money than you know what to do with, go ahead. Just be sure the equipment driving the images can provide what the HD monitor can take. This writer is sticking with the smaller monitor sizes.

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."

Rich

"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."

Gloria

"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."
