Analog vs Hi-Def Cameras
Versatech exclusively provides high definition IP video systems. IP video is the next generation of security surveillance which has replaced traditional “CCTV” (Closed Circuit Television) systems. Most of us have seen the images provided by CCTV systems throughout our lives (think of those blurry pictures of convenience store hold-ups featured on countless newscasts). CCTV used “analog” video cameras to transmit signals down a coaxial cable to a video monitor or recorder. High definition IP cameras are “digital” just like your digital camera, and the video footage they create is stored and transmitted using the same type of technology as the Blu-Ray player in your home theatre, or your PC when streaming video over the internet.
At their best analog video systems provide approximately 640 x 480 pixels or 0.3 megapixels of resolution (a megapixel = 1 million pixels). IP cameras come in many different resolutions including 720 p (1 megapixel), 1080p (2 megapixel) and higher resolutions for special applications. What this means is far clearer pictures, both in video and in still images. Think of the difference between a VCR played on an old TV versus a DVD on a high definition LCD monitor and you’ll get the idea. There is no such thing as a high-definition analog camera. You’ll see terms used such as “high resolution” or “700TVL” but these cameras simply don’t compare with a good quality high definition camera.
Below you’ll find some real world examples of analog versus high definition IP cameras taken from actual client sites. It’s not hard to see the benefits of IP over analog systems.
DAY TIME COMPARISON SHOTS
The images shown above are from actual footage taken from a client’s site where the camera was upgraded from a standard analog camera to an Axis P3364-VE high definition camera. Not only are the images clearer but you can also see how the high definition camera can better deal with the wide range of light levels typical on a sunny day. These images were taken on the same day at the same time.
NIGHT TIME COMPARISON SHOTS
The images shown above are from actual footage taken from a client’s site at NIGHT where the camera was upgraded from a standard analog camera to an Axis P3364-VE high definition camera. The P33 series cameras includes Axis Communication’s incredible “lightfinder” technology that uses a “P-Iris” lens technology, low light CMOS image sensors and software processing to create incredibly bright and clear footage even in low light night conditions. These two images were taken on the same night at the same time.
The two videos below were taken at exactly the same time using a client’s existing analog camera and the new Axis P3364-VE we replaced it with. Not only does the Axis camera have 3 times the resolution (640 x 480 compared to 1280 x 960) but the light handling, focus and colour are far superior.
Some of our competitors continue to sell analog systems. We feel that providing an analog camera system to a customer in this day and age would be like selling them a tube TV and a VCR for their new home theatre.
Of course, not all “high definition” cameras are of equal quality. Axis Communications of Sweden built the world’s first commercially available IP camera in 1996 and are now the world’s largest manufacturer of high definition network cameras. They are constantly at the forefront of camera technology and have a huge product catalog covering every possible camera need from the 720p wireless mini camera for $199 to high end cameras for specialized high applications such as PTZ control, thermal imaging, covert and 5 megapixel super high definition cameras.
If you have any doubt about the differences between an analog camera system and a high definition IP camera system we suggest you have us come out and shoot test images at your site, then have our competitor do the same. If you have an existing CCTV system we’ll shoot side by side comparisons with your current cameras. There is no cost for this service and no obligation to purchase anything. We just want you to experience the performance of the latest hi-def cameras can make before making any final decisions.
