A high degree of integration of high-speed dome camera, which integrates PTZ systems, communication systems and camera systems. PTZ system refers to rely stepping motor rotates to adjust the orientation of the part fastball monitoring, communication systems refers to motor control and for image and signal transmission part; camera system includes one machine movement. Between systems, the master CPU processor and power supply part plays the role of lateral connections, the power supply for the system, while the CPU is to maintain the normal operation of all functions of the camera. Changed little speed dome camera evolution theory in its implementation, the detail, the high-speed dome camera is a "differential stepper motor motor" structural achievements of its fast and accurate positioning and rotation, all this is by CPU issued instruction processing chip to perform, video and camera control functions and then written into the movement of RAM memory, and also the camera's many features, such as white balance, shutter speed, aperture, zoom, focus and other settings for the actual control projects. High-speed dome camera has several major hardware part is worth mentioning, the first motor part, then slip ring, followed by the power section and the control board, the drive belt is also very important. And its communication part way related to the communication protocol and protocol (Protocol), the protocol refers to the content of communications code way, way high-speed communication protocols ball mutual communication with the host system chosen means nothing to accept these communication protocols way to control instructions issued and communication. Generally speaking, the current high-speed dome camera RS-485 communication adopted more, but in the communication control character code string position and then all manufacturers are slightly different. 

In the video surveillance cameras, speed dome is the most perfect, either from the appearance, type or function, its lines perfect in appearance, but also both the infrared, low-light, wide dynamic function, but the era of all-weather surveillance applications , high-speed ball more large proportion of night vision surveillance monitoring applications, then infrared speed dome camera installation and operation and maintenance need to pay attention to what matters have it? infrared dome camera, infrared night vision dome camera, indoor and outdoor infrared speed dome cameras, video surveillance systems which are currently often used in night vision front-end image acquisition devices, due to the infrared speed dome camera integrates a high-speed dome camera control, an array of infrared light, power and PTZ control, integrated control of the zoom movement other functional modules, and its intelligent functions are increasingly rich, almost entirely an intelligent system, so when you install the infrared speed dome camera just remember the following precautions, you can easily install in and operating infrared speed dome cameras. 

First, pay attention to the size of the adequacy of the infrared power for optional infrared light, power should be possible to meet the maximum power it needs, otherwise the situation caused due to insufficient power irradiation distance occur frequently enough. Throughout the installation process must gently, so as to avoid collision infrared component damage and movement, to know to protect low failure rate high speed dome camera is its long service life. Installation should be taken to avoid direct glare,infrared speed dome cameras, whether installed indoors or outdoors, the installation position of the camera are not to choose at bright lights or reflective, but not long shooting a very bright object (such as a bright light ), they should not shoot infrared camera at the sun, not only will not play infrared start function is more likely to affect their monitor screen effect.infrared speed dome camera in an unstable light can cause fires, directly affect the overall monitoring results. During the installation process, many technical staff are like a hand to put tails infrared speed dome cameras,infrared speed dome cameras are directly connected to the interface cable slip ring, if directly pulling the cable, it is easy the emergence of the joint situation is bad, the best way is to use both hands to hold up high speed dome camera installation. During the installation of the camera, the power line to receive near-infrared high-speed dome camera, while the power cable infrared high-speed ball machine not to be extended, but can not use the camera focused on a multi-group mode power supply. If you use a centralized power supply to multiple infrared speed dome camera, it may lead to different distances or indoor and outdoor high speed dome camera infrared voltage and current uneven and inadequate, particularly during a lightning storm, the line resistance increase, supply voltage and current shortage is likely to lead to the motherboard infrared speed dome cameras burned, and thus can not be monitored. 

Also note that when you install shielded infrared speed dome cameras, IR speed dome camera installed in the vicinity do not have a strong electromagnetic energy radiation, such as radio or television transmitters, mobile phones, would be too close to the signal interference, affecting visual effects . Also note that when you install fastball rust problems south of the country and more rainy, rain, snow and fog and haze in the north as well as water vapor is the bane of almost all metal materials, if found to have corrosion monitoring accessories metal stents, must be timely maintenance and avoid fastball dropped or caused by loose screws monitor screen offset other issues. IR speed dome camera when installing wiring, be sure to distinguish the RS-485 communication protocol control and power lines, because many accidents are installed under the oversight of the engineering staff at RS-485 signal to the 24VAC power supply, so that the infrared speed dome camera control module may burn hot spot, so installation should seriously see the logo, and to protect the identity-related cables for the construction and future maintenance. IR speed dome camera installed in the indoor and outdoor use is completely different. When installed outdoors, be sure to carry out stringent water treatment, most people think that installing outdoor infrared high-speed dome camera itself is not to have the waterproof function? Having said that, but when you need to install fastball cable to connect with the outside world , there is always exposed wiring section, if the wiring parts and improper access lines, or are likely to cause the water seal is not good, especially when using the crane-mounted or wall-mounted bracket homemade, so we must seriously deal IR speed dome camera waterproof problem. 

Users in their daily regular cleaning speed dome camera, please wipe fingerprints or dust with a soft, dry cloth to remove dust by blowing up dust with a soft, dry cloth to wipe the body, if very stubborn stains, use a cloth dipped in a small amount of neutral detergent, then wipe dry. In the cleaning process can not use alcohol, gasoline or volatile solvents such as thinner, otherwise it will damage the finish. In the infrared speed dome camera maintenance should pay more attention to prevent aging equipment attachments, if infrared speed dome camera has to add a waterproof and dustproof or explosion-proof enclosure, then the elastic cable access device periodically check the gasket on becomes necessary, if found gasket loses its elasticity due to aging time and must be replaced with the same specifications of the components may not be used to replace other materials, to ensure its airtight and waterproof. Finally, when you install the infrared speed dome camera, select the appropriate power supply is very important, because if the power supply is too small, amounting to less than IR speed dome camera work rated power, IR speed dome camera main circuit board will continue to discharge the capacitor fever, IR speed dome cameras because the power is too large or too small, infrared heat will affect the LED light and cause its decay heat dissipation if not out, it will affect the sensitive components of the chip to the camera work, in addition to dangerous circuit due to overheating and burning will occur, we will also shorten the life of the camera. Even well above considerations are still not enough, another most important thing is to read the product instructions carefully, before and after the installation and maintenance checks done on and pay attention to whether each security step and follow the manual instructions IR speed dome camera setup and operation, in order to avoid trouble for himself.
