成都监控系统公司


Next, let's take a look at the mystery of Chengdu Monitoring System Company.

PTZ: In the previous introduction, we often mentioned PTZ, but some people do n’t have any perceptual knowledge about it. In fact, PTZ is an installation platform composed of two alternating currents, which can move horizontally and vertically. What we call a gimbal is different from a gimbal in a photographic equipment. Generally, a gimbal of a photographic equipment is only a tripod, which can only be adjusted by hand. The gimbal in the monitoring system is remotely controlled by the control system. Can control its direction of rotation. There are many types of gimbals: According to the use environment, it is divided into indoor type and outdoor type. The main difference is that the outdoor type has good sealing performance, waterproof, dustproof and large load. According to the installation method, it is divided into side installation and hoisting, that is, whether the gimbal is installed on the ceiling or on the wall. According to the shape, it is divided into ordinary type and spherical type. The spherical type head is placed in a hemispherical and spherical protective cover. In addition to preventing dust from interfering with the image, it is also concealed, beautiful and fast. When selecting a pan / tilt head, you must consider the installation environment, installation method, working voltage, load size, and also consider the performance-price ratio and whether the appearance is beautiful.

Bracket: If the camera is only fixed to monitor a certain position and does not need to rotate, then only the camera bracket can meet the requirements. Ordinary camera mounts are simple to install, inexpensive, and versatile. Common brackets are short, long, straight, and curved, and different models are selected according to different requirements. The outdoor bracket mainly considers whether the load capacity meets the requirements, and then there is the installation position, because from practice we have found that many outdoor cameras have special installation positions, some are mounted on telephone poles, some are mounted on tower cranes, and some are mounted on iron On the shelf ... Due to various reasons, the existing bracket may be difficult to meet the requirements and needs additional processing or improvement, so I won't say more here.

Protective cover: Protective cover is also one of the more commonly used equipment in monitoring systems, mainly divided into indoor and outdoor. The main difference between indoor protective covers is the size, appearance is beautiful, and the surface treatment is qualified. The function is mainly dust-proof and vandal-proof. The sealing performance of the outdoor protective cover must be good to ensure that rainwater cannot enter the protective cover and erode the camera. Some outdoor protective covers also have exhaust fans, heating plates, and wipers to better protect the equipment. When the weather is too hot, the exhaust fan works automatically; when it is too cold, the heating plate works automatically; when there is rain on the protective cover glass, the wiper can be started through the control system. When choosing a protective cover, first look at the overall structure. The fewer the mounting holes, the better the waterproofing, and then whether the internal circuit is easy to connect. Later, you need to consider the appearance, weight, mounting seat, and so on.

Monitor: The monitor is the standard output of the monitoring system. With the monitor, we can view the image sent from the front end. The monitors are divided into color and black and white. The sizes are 9, 10, 12, 14, 15, 17, and 21 inches, and 14 inches are commonly used. The monitor also has a resolution, which is expressed by the number of lines like the camera. In actual use, the number of lines of the monitor is generally required to match the camera. In addition, some monitors also have audio input, S-video input, RGB component input, etc. Except for the audio input monitoring system, most of the other functions are used for image processing, which are not described here.

Video switcher: Multiple video signals need to be sent to the same place for monitoring. One channel of video can correspond to one monitor, but the monitor occupies a large area and is expensive. If you do not require constant monitoring at all times, you can add a switch in the monitoring room. The output signal of the switch is connected to the input of the switcher, and the output of the switch is connected to the monitor. The input of the switch is divided into 2, 4, 6, 8, 12, 16 and the output is divided into single and Two-way, and audio can be switched simultaneously (depending on the model). The switcher has two working modes: manual switching and automatic switching. The manual method is to switch the switch to whichever channel you want to see. The automatic method is to delay the switching of the preset video in order. The switching time can be adjusted by a knob. Usually between 1 second and 35 seconds. Switchers are cheap (generally only three or five hundred yuan), simple to connect, and easy to operate, but only one image in the input can be viewed in a time period. To view multiple camera images on one monitor at the same time, a screen splitter is required.
