Camera resolutions - megapixels

Size isn't everything!

Megapixels = size of photos

The size of a photo can be measured in "megapixels". Hence, if a camera is quoted as being 5 megapixels, it means the camera can produce photos that are 5 megapixels in size.

(A megapixel is approximately 1 million "dots" - so a 5 megapixel photo contains 5 million dots)

Interpolation = artificially larger photos

Some cameras can "interpolate" photos to increase their size. This means the camera's sensor is capable of taking a certain maximum size photo, but software on the camera then artificially increases the size of the photo. It does this by creating space between the "dots" that make up the photo and then filling in that space with a colour that is similar to nearby dots. This filling in of colour is done programmatically - the filled-in dots were not generated by the sensor capturing light information.

For example, there are many trail camera models at the moment that are 5 megapixel cameras but which can interpolate images to 8 megapixels. In reality the camera is a 5 megapixel camera but the packaging almost always emphasises the "8 megapixels" (and then in small print may say "interpolated"). You could use any 5 megapixel camera and then use computer software to enlarge the camera's 5 megapixel images to a size of 8 megapixels and acheive the same effect.

Tiny megapixels = why do these cameras still exist?

There are some cameras in our product lineup that quote really small photo sizes.

The UOVision BG-30L is a 0.3 megapixel indoor security specialist camera. You can program it to receive input from up to 8 remote sensors that can monitor windows and doors using magnetic or passive infra-red PIR motion-activated switches. The camera can take photos and send MMS (multimedia message service, ie. picture SMSes) messages. It makes sense to have small image sizes for transmission via MMS and the camera will store a huge number of images on relatively small data cards.

The Reconyx SM-750 is a 1.3 megapixel license plate specialist camera. It is able to capture number plate information on vehicles traveling at up to 100 km/hr. Its photos are purely black and white - not greyscale. As such they require very little light information and the 1.3 megapixel sensor is adequate for its function. This camera can likewise store a huge number of photos on relatively small memory cards.

The Wildlife Monitoring BabyTrail BT-2A is a 2 megapixel budget camera designed for backyard and school classroom projects. It was brought onto the market with the lowest price point of its time. One way in which the pricing was kept low was to use the smaller sensor. However 2 megapixel photos are very much adequate for most hobby and enthusiast fauna investigations.

Large megapixels - how big do cameras get?

The vast majority of cameras in our product lineup are 5 and 8 megapixel cameras, with some being 5 megapixels interpolated to 8.

The largest camera we have stocked was the Leupold RCX-1 and RCX-2 cameras which were 8 and 10 true megapixels (not interpolated) respectively. Leupold ceased offering these cameras in the Australian market in 2014.
