High Speed Camera Introduction

High speed camera is a kind of intelligent cameras front, all named high-speed intelligent ball camera, or integrated High speed camera intelligent ball, or simply fastballs, abbreviation High speed camera. High speed camera is the most complex and comprehensive monitoring system works best camera performance, creating complex, price front, able to expensive and density, the most complex monitoring occasion.
The structure and principle of the High speed camera

High speed camera is a kind of integration quite high product, integration of the pan and tilt system, communication system, and the camera system, yuntai system is a motor drive, communication system of rotating parts refers to motor control and right image and signal processing parts, camera system integration refers to the heart of the blast. But a few big system, plays a horizontal between connected is a master core CPU and power supply parts. With each big electric part supply, many places between systems is USES diodes and transistors micro electric current power supply, and the core CPU is to realize all functions the normal operation of the foundation.

The principle of High speed camera is actually mentioned above roughly, and specifically, High speed camera using "precision differential stepping motor" implementing High speed camera rapid, accurate positioning, rotating. All this is issued by the CPU to realize the instructions. Then the camera images, video camera function written into High speed camera CPU, thus realizing the control, yuntai image transmission out, and to many of the camera features, such as white balance, shutter and aperture, zoom, also achieve control functions such as focus.

General High speed camera are divided into its part, shell parts and accessories section. Any manufacturer, there is a High speed camera with frame put your bag one conveying rate of heart, control decoding the mainboard and motor yuntai system centre to unify its parts, and with screws with shell part way or another connected centre is the core part, usually have a variety of appearance, shell, such as Pyle high appearance, panasonic appearance, and the design of your own appearance. Shell is usually adopt the aluminum alloy, also have plastic, alloy casting and the general and divided into two shell stamping. Aluminium plastic of good, stamping than the good than casting. Shell is under transparent bubble parts, transparent cover must use optical transparent bubble can ensure TongGuangLv and images without distortion, should also consider prevent ageing, prevent damage, dustproof, etc. Accessories section generally includes stents part, heater part, fan hot parts. Stents including wall outfit stent, the boom bracket, SMT suction a top, embedded suction a top don't need support, general outdoor ball are equipped with fan hot device, the heating device only in cold region, just oblique, indoor ball in principle no fan heat and heating parts. Accessories include power, general use of is all 24 fell 2 to 3 Ann current transformer power supply.

High speed camera a few major hardware component, first is motor, then sliping, then power part and control the mainboard. Transmission belt is also very important.

High speed camera communication problems involved and there is communication protocols and communication problems, communication agreement means High speed camera with host system, choose in communication communication protocols, such as pelco, mann yards, panasonic, Philip agreement. Communication refers to these communications protocol USES what way to communicate, such as 485 communication mode, 232 communication mode, 422 communication mode, coaxial visual control communication mode, generally speaking, High speed camera USES 485 communication, and communication protocol different manufacturers are different.
The functions and characteristics of High speed camera

High speed camera a few basic function, the first is fast operation, the second is smooth operation and the third is the positioning precision.

1, high-speed function: requirements presets a speed emphasize fast, basic reached 250 degrees/SEC above; Secondary control speed emphasize smoothly, control sensitive flexible, not too fast, not curt, support variable speed.

2, preset a function: must contain 64 above, and require the preset a preset position must accurate, after powrefailure can also memory this presets bits.

3, cruise scanning: must can set High speed camera in each preset bits can cruise scanning function between.

High speed camera and some advanced features:

1, track memory function: requirements High speed camera can memory more arbitrary trajectory route, and will track route through setting calls.

2, menu display features: can show a perfect operation menu, through the menu for running speed, preset a retention time, the mode of operation, etc, with the menu can modify the modification, and camera parameters, automatic tracking and privacy programming cover, and other functions.

3, take alarm input/output: in High speed camera on add an alarm input output module.

4, network High speed camera, fiber High speed camera: in High speed camera in video server module integrated network again. The or light module block
