High speed camera application note

1, high speed camera does not apply to any occasion
Of course, high speed camera does not apply to any occasion, high speed by its own fast ball structure factors, the in some cases is not suitable.Most of the high speed on the market at present, the fast ball CCD dimensions are for 1/4 ", this determines the photoelectric conversion efficiency is lower than the third "the CCD camera, gun type In addition, due to the volume of the high speed camera machine is limited, and the larger and accommodate change x optical variable times, this determines the lens change its optical lens small in size. The Times Plus almost all of the fast ball, the optical lens all by several groups of lens, through the light in the lens of reflection refraction and between groups, etc. So as to the corresponding optical variable times multiples. Obviously, the light in the lens of reflection refraction and group, will be part of the energy loss, so eventually into CCD light is weak, this will affect the efficiency of the photoelectric conversion. So, to intensity of illumination is not enough, or require all occasions day and night to clear imaging and at night without enough Ming occasions, according to intelligence is not suitable for high speed fast ball. For example: need some larger scorched 200 mm focal length (far above), and intensity of illumination of poor environment, if PTZ+ high performance or big configuration zoom lens camera, the effect will be better than the intelligent fast ball. 
Therefore, the application of high speed fast camera also needs according to actual monitoring environment make a proper judgment

2, avoid blindly seek high performance, and the Angle, high speed rotating
In the selection the ball, need to choose according to actual needs, and avoid blindly the high performance, and the pursuit of Angle, high speed rotating, such as performance.
For example, a design scheme when decentralizing need to install a quick ball, according to the actual installation and use of the environment, to confirm that the fast ball USES is with wall or pillar when installed, it can choose the whole Angle (the horizontal Angle is 360 degrees, the vertical direction to rotate 180 degrees of rotation) fast ball. Just think, when the wall with the fast ball rotation, the level of more than 180 degrees or 90 degrees in vertical big fancy, the monitor screen after appear in the picture??? What??? -will be wall or ground, and this kind of picture it, no sense of monitoring. This type of installation, can choose level 350 degrees, 90 degrees of rotation vertical economical fast ball.
Proper choice, not only can fast ball to see the effect of the prison of the same purpose, at the same time, also can dramatically reduce the cost of system. For example, the structure for quick ball made two quick ball, the rotation angles differ only 10 degrees, but the cost for rotary motor is different, its price difference can be more than 40%. Therefore, in the choice of fast ball, also need to consider to see distance, prison prison see a target characteristics, can according to different prison see distance to choose different optical variable times the equipment.
