What do we mean by Image Usability? It’s about making sure that your cameras have what it takes to capture the images that meet your needs. Get it wrong and it could cost you in more ways than one. So, if you’re on the hunt for security cameras, here are some points you can’t afford to ignore.

“Can you see in color in the dark? I can. Even with just 0.05 lux to play with – that’s 5% of the light of one candle – Lightfinder technology can capture excellent color images.”
Move the slider to see how Lightfinder lets you see in color in the dark.
Even with no moonlight, Lightfinder can produce full color images.
“What’s Wide Dynamic Range? It’s how we handle extreme lighting conditions. Imagine wearing sunglasses and carrying a torch at the same time. You can control the glare and light up the dark simultaneously.”
Wide Dynamic Range (WDR) is also referred to as High Dynamic Range (HDR)
With Wide Dynamic Range, you can see inside and out, perfectly, at the same time.
“I’ve got HDTV at home. The detail’s amazing. With our HDTV cameras, it’s five times sharper, making identifications – even at long range – as easy as, well, watching TV.”
Compared to surveillance a few years ago, today’s HDTV 1080p network cameras capture images that are almost 25 times bigger.
“Axis’ HD surveillance cameras meet the standards laid down by the Society of Motion Picture and Television Engineers.”
“You know when you have to screw your eyes up in bright sunlight and everything goes a bit blurry? Well, that’s where P-Iris comes in. It adjusts automatically to the light conditions, but keeps diffraction and blurring to a minimum.”
The iris helps control the depth of field i.e. what is in focus. Generally, the smaller the iris, the longer the depth of field.
The iris also controls the amount of light hitting the sensors. The smaller the iris, the less light will get through.
“The world isn’t always landscape shaped. Sometimes things are upright. Thanks to Corridor Format, we’ve got them covered – without wasting large chunks of the frame and recording vast areas of blank wall space.”
A well-positioned camera can give you 75% more usable content.

“If you want to see in the dark, you need infrared (IR). Our built-in IR LED lights kick in at night giving us high-quality, low-noise video at any time.”
Cameras can capture IR light from part of the spectrum that is invisible to the naked eye.Infrared Visible light UV
Axis’ infrared cameras with IR lights work in the dark and low-light conditions up to a range of 30 m (100ft).
“You can run, but you can’t hide. Thermal cameras detect and create images based on heat, through darkness, haze, smoke and dust. And without the need for any extra light sources, they keep a really low profile.”
“Thermal cameras won’t help you identify people, so they’re often used alongside conventional cameras.”
Axis’ thermal network cameras get their power over the Ethernet; they don’t need any external power supply, making installation quick and easy.
