Megapixels and CCTV

The word pixel is derived from ‘pix’ (picture) and ‘el’ (element) and is the smallest item of information within an image. Digital images are made up of thousands of these tiny, tile-like picture elements that each records a specific intensity of a single primary color of light (red, green or blue). The more pixels the image has, the higher the image resolution will be. A megapixel (one million pixels) is the term used to describe a large number of pixels in an image, or the number of image sensor elements in a digital camera or the number of display elements in a digital display.

High Definition (HD) is a type of megapixel camera; it’s just that HD is one specific type of megapixel camera in the megapixel family. For example, HD is limited to a maximum resolution of 2.1 megapixels; it has a slower frame rate and an aspect ratio of 16:9. HD is wonderful for certain applications and other types of megapixel cameras offer many more formats, aspect ratios and pixel numbers for other applications.

More and more security professionals are seeing the true value of integrating these high-resolution megapixel surveillance cameras into the existing systems monitoring their facilities. With higher resolution, the camera images are clean and clear which eliminates the need for overlapping camera coverage of areas, reducing the number of cameras needed to cover a single area and generally providing a better overall situational awareness. Combining megapixel cameras with other specialized cameras (such as thermal image, IR or P/T/Z) creates a system that is very effective, reliable, and cost-efficient.

These cameras are definitely a must in applications where details are critical for identification purposes; banks, airports, government facilities and other high-security areas, and also retail locations requiring point-of-sale monitoring are all good examples. With the high resolution and greater image detail, the security personnel can zoom in on specific portions of the recorded, or live, scene to identify objects, individuals or license plate numbers. Megapixel surveillance cameras can cover a wider area with exceptional detail; these cameras can provide detailed information that would be impossible to make out with a standard analog CCTV camera.

If you are concerned with megapixel cameras eating up your DVR/NVR hard drive space – worry not! Megapixel surveillance cameras only take up a little more hard drive space on your NVR/DVR that a standard security camera would.

Transmitting megapixel images via IP also requires a little more bandwidth than a standard analog CCTV camera; however you can minimize this increase by using the 16:9 aspect ratio (unavailable from analog cameras) which eliminates the upper and lower portion of the scene, parts that usually contain unimportant details, thus lowering the amount of bandwidth and storage space taken up by useless data.

Megapixel network cameras have a very important role to play in video surveillance applications, although they are more suited for one location over another, these cameras are easily integrated into existing installations, easily added to new proposals for installations, they are easy to use, they are cost-effective and they provide superior image quality when crystal-clear images are an absolute must.

Ventura’s Police Department has a new recruit! WTI’s Sidewinder camera.

In the beginning of July, the City of Ventura’s Police Department installed WTI’s revolutionary Sidewinder P/T/Z camera on the top of the mast of their mobile command center. The Sidewinder has been used as a mast camera for the broadcast industry, fire departments and now our local law enforcement. It is the perfect mast camera because it will see all of the surrounding areas with its super fast pan, tilt and zoom functions.



The Ventura Police and Fire Mobile Command Post is used all over the county at community events, emergency situations and crime scenes; incorporating the Sidewinder into law enforcement projects provides exceptional exterior video surveillance at any location. The Ventura Police Department is always on the cutting edge of technology and they have been the example for many departments all across the nation. Having the Sidewinder on top of their command post mast is just another example of their high-tech and innovative philosophy at work.



The Sidewinder is a color day, black and white nighttime DSP camera with electronic image stabilization. It has continuous 360° rotation in both pan and tilt axes. Its 35X optical zoom lens gets great close-ups to help law enforcement with suspect identification. It also has a high-tech electrically conductive and hydrophilic “self cleaning” glass face-plate window with a thermostatically controlled heater.

So watch out bad guys because the Sidewinder is watching you!
