A guide to IR or infra red night time range on cctv cameras.
What is the meaning of IR in CCTV camera?
Infrared cameras (IR) are sometimes referred to as IR cameras or “Night Vision Security Cameras” because of this.Infrared Cameras can capture acceptable video in total darkness and even better quality video in low light.
How do IR CCTV cameras work?
In order to see at night, most CCTV cameras use infrared (IR) technology.These emit infrared light at night, which allows the camera to see even in total darkness. Infrared light is invisible to the human eye, which is why burglars cannot see that the CCTV camera is activated.
What is IR and IP camera?
This category is comprised of IP CCTV cameras that we offer which feature integrated infrared illumination to help enhance night-vision. It consists of a range of indoor and outdoor, static and PTZ models; some of which also include optimised IR technologies to help prevent over exposure.
What is IR range?
Infrared radiation (IR), also known as thermal radiation, is that band in the electromagnetic radiation spectrum with wavelengths above red visible light between 780 nm and 1 mm. IR is categorized as IR-A (780 nm-1.4 µm), IR-B (1.4-3 µm) and IR-C, also known as far-IR (3 µm-1 mm).
What is the maximum range of infrared in meters?
The infrared range is usually divided into three regions: near infrared (nearest the visible spectrum), with wavelengths 0.78 to about 2.5 micrometres (a micrometre, or micron, is 10–6 metre); middle infrared, with wavelengths 2.5 to about 50 micrometres; and far infrared, with wavelengths 50 to 1,000 micrometres.
Do all cameras see infrared?
Yes all cameras can see ir rays. But only special film or digital sensors can capture infrared.
Are all cameras infrared?
While most digital cameras have built-in filters to block infrared light, some do not.A digital camera where the lens system passes infrared light, and where the sensor is sensitive to infrared light, is easy to use for infrared photography.
How do I know if my camera is infrared?
Test you camera
If you can see a light from the remote your camera will capture IR light. This only means that the camera sensor can “see” a bigger light spectrum than the human eye can, but it will “see” the Infra Red (extreem Red light) like white light.
Which is better CCTV or IP camera?
IP cameras offer higher resolution video and better picture quality than CCTV cameras. CCTV cameras offer lower resolution video and less picture quality than IP cameras.

What is infrared lamp good for?
Infrared lamps help to target cells in your body and assists them with absorbing more energy. The lamps can be aimed at a specific area of the body for a certain period of time to relieve colds and tension, and improve blood circulation.
What is infrared used for?
Infrared (IR) light is used by electrical heaters, cookers for cooking food, short-range communications like remote controls, optical fibres, security systems and thermal imaging cameras which detect people in the dark.
What wavelength is far infrared?
| SPECTRAL REGION | WAVELENGTH RANGE (microns) | TEMPERATURE RANGE (degrees Kelvin) |
|---|---|---|
| Near-Infrared | (0.7-1) to 5 | 740 to (3,000-5,200) |
| Mid-Infrared | 5 to (25-40) | (92.5-140) to 740 |
| Far-Infrared | (25-40) to (200-350) | (10.6-18.5) to (92.5-140) |
What is the difference between infrared and near infrared?
Infrared light has a range of wavelengths, just like visible light has wavelengths that range from red light to violet. “Near infrared” light is closest in wavelength to visible light and “far infrared” is closer to the microwave region of the electromagnetic spectrum.
Is infrared radiation harmful?
Prolonged exposure to IR radiation causes a gradual but irreversible opacity of the lens. Other forms of damage to the eye from IR exposure include scotoma, which is a loss of vision due to the damage to the retina. Even low-level IR absorption can cause symptoms such as redness of the eye, swelling, or hemorrhaging.
Why is infrared light hot?
Infrared energy is felt as heat because it interacts with molecules by exciting them, causing them to move faster which increases the internal temperature of the object absorbing the infrared energy.
What color is IR light?
If you’re a scientist, the color of infrared light is between 1 and 700 nm wavelength, but, for the rest of us, infrared light is the same color as all other light. It’s colorless. Infrared radiation doesn’t have a colour because our eyes aren’t evolved to see it.
What does infrared look like?
In infrared light, hot things look bright yellow and orange. Items that are colder, such as an ice cube, are purple or blue. We use infrared cameras to help us see things.
What does seeing in infrared look like?
Infrared. If you could see infrared light, you would see a world of temperature—not color. Any object that has a temperature radiates in the infrared part of the spectrum (even ice). The hottest objects would appear brightest, so the sun will still be at the top of the list.
