What is an IR CCTV camera?
Infrared security cameras have the capability to capture video in low light and no light (0 Lux) areas. Infrared cameras (IR) are sometimes referred to as IR cameras or “Night Vision Security Cameras” because of this. The best infrared cameras use a technology called “Smart IR”. …
How does IR work in CCTV?
Infrared picks up how much heat an object or person has, since everything on earth puts out some form of infrared light depending on its temperature. Infrared CCTV cameras use infrared LED lighting positioned around the outside of the camera lens in order to capture information.
What is smart IR CCTV?
Smart IR is a technology built into some security cameras that adjusts the intensity of the camera’s infrared LEDs to compensate for the distance of an object so that the infrared does not overexpose the object.
What is the use of IR camera?
An infrared camera (also known as a thermal imager) detects and measures the infrared energy of objects. The camera converts that infrared data into an electronic image that shows the apparent surface temperature of the object being measured.
Do CCTV cameras use infrared?
“Day/Night Cameras” Versus Infrared Light for CCTV Cameras A day/night camera does not use infrared technology and requires some light to capture video or stills.
Why do cameras use infrared light?
Thermal, or infrared, detection systems utilize sensors to pick up radiation in the infrared part of the electromagnetic spectrum. An infrared camera detects the thermal energy or heat emitted by the scene being observed and converts it into an electronic signal. This signal is then processed to produce an image.
What is Smart IR video?
This feature will allow a daytime video clip to keep recording as long as the camera detects movement during filming. If the subject stands still in front of the camera and the camera does not detect movement, the camera will end the video clip at the designated time chosen in the setup menu.
What is IR intensity?
Intensity: Changing the intensity adjusts brightness of the IR illumination. This value can be set to Low, Medium, or High, to affect glare or which objects can be seen clearly in the dark.
What is IR wavelength?
Wavelength range and sources 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 IR distance?
The IR distance is the distance from the camera that the infra red LEDs can illuminate. It’s a largely useless number and you will never be able to identify someone at this distance. All cameras that have on board infra red illumination will illuminate objects at the identification distance for the lens fitted.
Can a CCTV camera be used with smart IR?
The below image compared a CCTV camera with smart IR to one without. The camera with smart IR that was used for the video capture had an infrared range up to 100 feet, but as you can see, it is able to adjust the intensity of the IR LEDs for the man that approached the camera within 3 feet.
How does an infrared camera work on a CCTV camera?
Infrared security cameras use built-in IR LEDs, an IR cut filter, and a photon detector (light level sensor) to enable their “infrared / night vision mode”. The photon sensor is used to detect when light levels are low. When light level goes below a certain level, the camera’s infrared LEDs automatically turn on…
How is IR-cut technology used in security cameras?
IR-Cut technology is used in many fields, especially in security cameras. IR-Cut security camera is the security camera has a IR-CUT filter built-in to make camera provide true color reproduction high quality image at day and night.
What does the IR range on a camera mean?
Widely used in marketing the IR range is a pretty much made up number and is supposed to give an indication of how far from the camera you can detect its built-in IR illumination. There is no relationship whatsoever between the IR “range” and the distance at which detail can be captured, the effective range of the camera.
