Buy The Wholesale Security Cameras With Mobile Application

Recent advances in ultra-low temperature (MCT or HgCdTe) infrared cadmium-mercury telluride technology have led to the development of high-performance thermal imaging cameras for a variety of complex thermal imaging applications. This cctv wholesale is available in shortwave, mediumwave, longwave or dual spectral ranges. There is also a wide range of camera resolutions due to medium to large detector arrays and different pixel sizes. CCTV wholesale features also include high frame rate shooting. Event Playback Adjustable Viewing Time This allows you to record temporary thermal events. With advanced processing algorithms, it increases dynamic range, prevents saturation, and improves sensitivity. These infrared cameras can be adjusted so that the obtained digital value corresponds to the body temperature. This algorithm includes an asymmetry correction that is independent of the exposure time. The features and functionality of these thermal imaging cameras enable a range of thermal imaging applications that were previously not possible.

The heart of the high speed infrared CCTV wholesale cameras is the cool MCT detector. Provides exceptional sensitivity and versatility for rapid thermal events.

Range of spectral infrared sensitivity CCTV wholesale

High-speed infrared CCTV camera wholesale with a wide range of MCT detectors are designed to operate in a variety of spectral ranges. The spectral range can be controlled by changing the composition of the HgCdTe alloy and the set temperature of the detector. The result is a single-band infrared detector with exceptional quantum efficiency. The signal-to-noise ratio (typically over 70) allows very small levels of infrared signals to be detected. Single-sideband MCT detectors are typically found in one of five different spectral ranges:

  • Shortwave infrared camera - visibility up to 2.5 microns.
  • Broadband infrared camera - 1.5-5 microns
  • Medium wave infrared (MWIR) camera from -3 to 5 microns
  • Long-wave infrared camera with a sensitivity of 7-10 microns.
  • Longwave VLWIR camera - sensitivity 7-12 microns

Best home security alarm system

Apart from cameras that use infrared detectors for home security alarm system. "Single spectrum" with the spectral response of the frequency band. New systems are being developed that use dual-band infrared detectors (referred to as "dual-band" or dual-band). For example, this is an MWIR / LWIR response chamber covering both 3-5 micrometers and 7-11 micrometers. SWIR and MWIR bands or two MW bands.

Reasons to use the infrared cameras

There are several reasons why the spectral range of infrared cameras is stimulated. For some applications, the desired spectral range is determined by the spectral spread or reflection of the observed object. These applications include spectroscopy. Laser beam width detection and level signature analysis Purpose of the phenomenology of photographing cold objects Marine observation

You can also choose the spectral range due to dynamic range issues. This dynamic amplification is not possible with infrared imaging in the MWIR spectral range. The wide dynamic range characteristics of an LWIR system can be explained by comparing the current in the LWIR range with its calculated current in the MWIR range. Planck Curve When viewing scenes in the same body temperature range, the flow distribution created by an object with a large temperature difference in LWIR is less than MWIR. In other words, wholesale security cameras can detect and measure objects at room temperature with high sensitivity and accuracy. However, for very hot objects (eg> 2000K), shooting over a wide temperature range with MWIR can be a serious problem. This is due to the fact that the signal from hot objects must be significantly attenuated. As a result, the photo is less sensitive to background temperature.

Due to the use of infrared sensors and detectors with different pixel sizes, there are high-speed infrared cameras with different resolution characteristics. Applications that do not require a high-speed, high-resolution infrared camera with QVGA detectors provide excellent performance. The pixel array 320 25 256 30 microns is known for its very wide dynamic range. Because it uses relatively large pixels with deep holes. Abnormally high noise with low sensitivity

Infrared detector arrays are available in various sizes. These are mainly QVGA, VGA and SXGA. As shown, VGA and SXGA arrays have much denser pixel arrays. Offers higher resolution than QVGA, is inexpensive and has large sensitive pixels for superior dynamic range.

Recently, smaller pixel infrared camera technology has produced a 15 micron detector that is one of the most impressive thermal imaging images to date. Widescreen cameras create high-resolution, high-contrast images for high-resolution and low-resolution applications. The optical system is also small.
