CCD cameras can be roughly divided into the following categories:
According to the imaging color:
(1) Color camera: It is suitable for distinguishing details of scenery, such as distinguishing the color of clothing or scenery. The amount of information increases due to the presence of color. The amount of information is generally considered to be 10 times that of a black and white camera.
(2) Black and white camera: It is used in areas with insufficient light and where lighting equipment cannot be installed at night. When only monitoring the position or movement of the scene, a black and white camera with a resolution generally higher than that of a color camera can be selected.
According to the camera resolution:
(1) Low-end type with image pixels of about 250,000 pixels (pixel), a color resolution of 330 lines, and a black and white resolution of about 420 lines.
(2) Mid-range image with image pixels between 250,000 and 380,000, color resolution of 420 lines, and black and white resolution of 500 lines. (3) Image with more than 380,000 points and color resolution greater than or equal to 480 lines, Black and white resolution, high resolution above 570 lines.
According to the sensitivity of the camera:
(1) Normal type: the illuminance required for normal work is 1 ~ 3 Lux
(2) Moonlight type: illuminance required for normal work is about 0.1 Lux (3) Starlight type: illuminance required for normal work is less than 0.01 Lux (4) Infrared illumination type: in principle, it can be zero illuminance, using infrared light source imaging.
According to the size of the CCD target surface of the imaging element:
(1) l inch target size is 12.7mm wide x 9.6mm high, 16mm diagonal
(2) The size of the 2 / 3inch target surface is 8.8mm wide x 6.6mm high, and the diagonal is 11mm
(3) The size of the 1 / 2inch target surface is 6.4mm wide x 4.8mm high, and the diagonal is 8mm
(4) The size of the 1 / 3inch target surface is 4.8mm wide x 3.6mm high, and the diagonal is 6mm
(5) The size of the 1 / 4inch target surface is 3.2mm wide x 2.4mm high, and the diagonal is 4mm
(6) 1 / 5inch is under development and no official products have been launched yet
In addition, CCD cameras are divided into PAL system and NTSC system, and can also be divided according to the image signal processing method or according to the camera structure area.
Overhead sectional door most widely used for loading areas on all types of industrial premises and Designed with a curved overhead track, these vertically-opening sectional doors can be installed in areas with reduced head room. They provide heat and sound insulation with its composite panel construction.
The counterbalance and cable system provides quiet and straight forward operation for manual doors. Electric operation is available for larger applications that can incorporate many alternative operator options to suit all client requirements.
The standard outer panels are manufactured from 0.5mm thick, high quality zinc coating to BS EN 10147
For the best weather protection the sectional door panel has an interlocking hinged joint integrating a high quality seal the full length of the panel.
A counterbalance system is incorporated into the sectional overhead door to ensure efficient and effortless operation.
The counterbalance comprises of springs mounted on a steel shaft that are high tensile helical wound steel. It has been heat treated for enhanced performance for around 50,000 cycles.
Reducing shaft friction is achieved with the aid of brackets and guide rollers incorporating highest quality sealed bearings.
