cctv camera types
Ka Xin Da camera and CCTV camera
The Kazinda lens was a lens with specific parameters. For example, the Kazinda 35mm f/1.7 manual biscuit lens was a standard lens among micro-lenses. It was a fixed-focus lens. The lens structure was five groups of six pieces. There were many types of bayonet. The focusing method was manual focusing. The maximum aperture was F1.7, and so on. It was suitable for photography.
CCTV lenses such as Mu Tengguang's 10-million-pel, infinite field of view CCTV lenses were widely used in industrial testing, automaton, electronic communication, semiconductor, biomedicine, scientific research, and other fields. They could improve efficiency and accuracy in the fields of semiconductor, chip inspection, security equipment, one-dimensional code and two-dimensional code identification, medical testing, biomedicine identification, and industrial product testing.

What are the types of camera projections?
Cameras had two main projection modes, one was an ortho-projection, and the other was a perspective projection. In an ortho projection, the distance between the object and the camera had no effect on the rendering result. No matter how far the object was from the camera, the size of the rendering would be the same. This kind of camera was usually used in two-dimensional games, also known as parallel projection. It could project all the objects in the scene onto the observation plane through parallel light rays. The effect of perspective projection was closer to the real world. The farther away the object was from the camera, the smaller it would be rendered. Perspective projection used a pyramid as the viewing cone, and the camera was located at the top of the pyramid. The pyramid was cut off by two planes to form a prism. Only the model inside the prism was visible. Its purpose was to transform the prism into a cube, thus producing the effect of near big far small.

Various types of camera viewfinders
There are many types of camera viewfinders, and the following are introductions by different categories:
1. * * According to whether the framing optical axis and the photography optical axis overlap **:
- * * Coaxial-type viewfinder **: The optical axes overlap.
- * * Side axis viewfinder **: The optical axes do not overlap.
2. * * According to the virtual image **:
- * * Real-image viewfinder **: Images as a real image.
- * * Virtual image viewfinder **: Images a virtual image.
3. * * According to actual structure **:
- * * Framed viewfinder **.
- Newton viewfinder.
- * * Inverse Galilean viewfinder **
- * * Kepler viewfinder **
- * * Alba viewfinder ** and so on.
4. * * According to working principle **:
- * * Range-axis viewfinder **.
- * * Single lens reflex coax viewfinder **.
5. * * From the perspective of the user **:
- * * Side Axis Head-Up Optic viewfinder **.
- * * LCD viewfinder (color LCD display)**, most of the popular lightweight digital cameras have this design, only a few models of DSLR digital cameras have it.
- * * EVF viewfinder (electronic viewfinder)**, some digital single-lens reflex cameras have this design.
- * * SLRTL viewfinder (single lens reflex viewfinder)**, this viewfinder is mainly used in digital single-lens reflex cameras.
6. * * Other types **:
- * * Reflective viewfinder **, a top-view viewfinder and side-view viewfinder for dual-lens reflex cameras and single-lens reflex cameras. It relies on reflection to peep at 90 degrees.
- A special viewfinder that had been around for more than 60 years. When both eyes were opened at the same time, one side would look at the viewfinder while the other side would look outside. A framed image would automatically be generated in his mind.

There are several types of storage format in the camera
The storage format in the camera was commonly used, such as JPEG, TIFF, RAW, etc. It might even support the HEIF format. Different storage format had their own characteristics. For example, the JPEG format was a loss-compression format. The file took up a small space, was fast to read, and was easy to view, but the post-processing space was limited. The RAW format was a raw data format, which retained the original information of the shot and had more post-processing space. The TIFF format was a non-compressed format. The HEIF format could greatly reduce the file size while ensuring good image quality.

What are the types and differences of industrial camera lenses?
In the field of industrial automaton, industrial lenses can be divided into the following types according to different application needs, each type has its own unique functions and characteristics:
1. ** Zooming lens **: This is an industrial lens that can change the magnifying power. It is commonly used in machine vision systems to detect objects of different sizes or to magnify images at different magnifying powers. The magnifying power can be adjusted as needed to meet different detection needs.
2. ** Multicentric lens **: It is a special industrial lens that can eliminate the error caused by the change in the distance between the lens and the object being measured. It can ensure that within a certain field of view, no matter how the distance between the object and the lens changes, a clear image can be obtained. It is often used to detect the size of the work piece.
3. ** Fixed focus industrial lens **: Its focal length is fixed and cannot be adjusted. It usually has a high resolution and a fast acquisition speed. It is suitable for machine vision systems that require high image clarity. The advantages are moderate price and stable performance, but the scope of application is relatively narrow.
4. ** Line scan lens **: Commonly used to inspect high-speed or continuous materials (such as metal, plastic, paper, fiber, etc.). It can achieve high-speed and high-precision inspection.

What are the best types of camera shots for shooting jewelry?
When shooting jewelry, a macro lens was the most suitable type of lens. For example, Canon's EF100mm f/2.8L Macro IS USM or RF100mm f/2.8L Macro IS USM, Tamron 90/2.8SP, Nikon's AF60mm f/2.8D Micro, Canon's Baiwei head EF100/2.8USM Macro, etc. You can also choose a lens with a focal length of about 60mm. This lens can make the camera reach 0.5 times when it is not far from the subject. If conditions permit, it is better to buy a macro lens that can shoot at a 1:1 ratio. In addition, standard lenses such as 50/1.2 or 1.4 could also be used to shoot jewelry. Canon's TS-E45/2.8 or TS-E90/2.8 could also be considered.
