There are many types of heads:
According to the use of the environment is divided into indoor and outdoor type, the main difference is that the outdoor type of sealing performance is good, waterproof, dustproof, load.
According to the installation method is divided into side mounted and suspended, that is, whether the head is mounted on the ceiling or mounted on the wall.
According to the shape is divided into ordinary and ball type, ball head is placed in a hemispherical, spherical shield, in addition to prevent dust interference with the image, but also hidden, beautiful, fast.
When selecting a head to consider the installation environment, installation methods, operating voltage, load size, but also to consider the performance-price ratio and whether the appearance is beautiful and other factors. Security monitoring head security monitoring head
Question 2: security monitoring head of the head role The head, the shield to the camera and the lens to provide a suitable working environment, and can realize the shooting angle of the horizontal and vertical adjustment. Decoder is the head, lens control of the core equipment, through which it can be realized using the microcomputer interface through the software control lens, head, installed in a fixed head camera can be adjusted to adjust the camera's horizontal and tilt angle so as to achieve the calibration angle.
Question 3: What is the difference between a multi-function camera (PTZ) and a security camera? Are they both used for monitoring? Thanks! The camera (PTZ) is a 360-degree rotation; the camera is ordinary, usually fixed in one orientation.
Question 4: What is the composition of the camera with PTZ structure? Surveillance if only the surveillance camera is not able to complete the monitoring work, it needs to use other aids to complete the entire monitoring process, which leads to today's topic - PTZ. This article is mainly on the role of the monitoring camera head and the composition of the structure to do a simple analysis. The role of the PTZ is to extend the surveillance camera monitoring range, it can realize the up and down and left and right rotation, the surveillance camera mounted on it, to achieve multi-angle monitoring. Surveillance camera PTZ is not a camera, it is just a special bracket, PTZ by constantly adjusting the angle of the bracket to extend the monitoring field of view area. According to the angle of rotation of the head can be different horizontal type head and omni-directional type head, through the control line, people can remote control to change the monitoring camera monitoring angle, to realize multi-angle monitoring.1, the camera in general when it comes to the video camera, naturally associated with the home video camera. In fact, monitoring cameras and home video cameras have a lot of different, first of all, fundamentally different design standards, one is designed for industrial applications, one is designed for home use, so they work for a long time, the requirements of the operating environment is very different; volume, monitoring the use of the machine is compact, while the home machine will be all the control part and tape all mounted in the same enclosure, so the volume to be much larger! In terms of volume, the home machine is small in size, while the home machine is much larger in size because all the control parts and tapes are installed in the same housing, and it must be controlled manually on the spot, and it is not possible to realize remote control from other places; in terms of key resolution, the home machine is generally about 300 lines in the horizontal, while the monitoring machine is for taking in the blackboard board, and the horizontal resolution should be above 400 lines. Each classroom to install a JIYEL JY-803 integrated color camera, 480TV line center resolution, 1Lux low illumination, with automatic white balance, backlight compensation and automatic electronic shutter adjustment, built-in 22 times the optical lens. 2, the lens is divided into fixed-focus lens and zoom lens. Zoom lens focal length variable, can be pulled closer or pushed away from the scene, to achieve several times the zoom effect, using it can be clearly photographed on the blackboard board, but also the entire classroom photographed, fixed-focus head can not be realized this function. The lens is a motorized three-variable lens with zoom, focus and aperture adjustments. Zoom can bring the picture closer and push it farther, change the angle of view and imaging size; adjust the focus and aperture, you can adjust the clarity of the image. The classroom teacher or a student's headshot can be clearly framed in real time on the entire screen, can also be pushed to the class situation like. 3, PTZ is a camera can be driven left and right, up and down the rotation of the equipment, with it, you can realize the full range of video cameras in the classroom. Generally speaking, a fixed camera, only to see about 60% of the students in the classroom, and the use of the camera with a PTZ can see the classroom in all directions and the podium, blackboard. It can be mounted on the wall or ceiling. Select JIYEL produced JY-8009 type indoor global shaped head, with a small size, beautiful appearance of the characteristics of the 4, listening to the head it is a highly sensitive and compact microphone. Select TD produced by the TD-701 series of monitoring head can be. 5, the protective cover it for the camera to provide further protection against certain damage, but also play a beautiful decoration and a certain degree of concealment. 6, the control host which is the heart of the system, all the other equipment to be connected to the control host, it is through the keyboard or the computer within the multimedia software to receive your control operations, and then control other equipment to realize it, such as: the head of the computer to realize it, it is a very important part of the system. Equipment to realize it, such as: the rotation of the PTZ, the lens doubling, focusing, aperture change. It can also be selected by you to the camera screen to the monitor you want to display, but also to make these different camera images in order to display the screen, each camera shows a certain amount of time, which can be adjusted, this function is called switching, it greatly simplifies your operation. The system host can take four keyboards and eight monitors, up to 64-way camera input, can fully meet your requirements. Considering the redundancy of system expansion and upgrading, the video and audio matrix switcher, the number of video inputs should be greater than the actual number of roads required, while with RS-232 and RS-485 communication interfaces, can be arbitrarily connected to the keyboard master, keyboard sub-controller, multimedia master, multimedia sub-controller. 7, monitors and televisions have a lot of differences, the largest place is the resolution, the horizontal resolution of the TV set Only about 300 lines, while the monitor is generally more than 400 lines, if you want to show the details of the object part, such as the words on the blackboard, which is essential. 8, decoder it is the host and front-end equipment between the "translation", it is the host to send the action of the command translated into the rotation of the PTZ, the lens changes in the required drive voltage and power. Drive the corresponding camera, electric three ...... >>
Question 5: What does security do? Security refers to safety precautions.
The security issue is the whole society *** with the concern of a major event, so security is the industry, especially with potentially dangerous high-risk industries need to pay attention to a work.
The security work of various industries by different departments, such as enterprise safety production in China by the State Administration of Work Safety in charge. Social security prevention by the public security department together with social forces *** with the management. Medical-related security is managed by the Ministry of Health and other organizations.
Security mainly includes: monitoring system, infrared perimeter alarm system, home burglar alarm system, building intercom system, parking management system, community card system, three meter reading system.
Security technology
Security monitoring generally includes security and television monitoring, used to be used in financial institutions and important departments, and now more used in all walks of life.
Security includes burglar alarms, access control management, electronic patrol, emergency call and so on. Engineering burglar alarm system equipment including alarm host, alarm output devices, alarm linkage equipment, front-end equipment (infrared and microwave intrusion detectors, door and window magnets, vibration detectors, glass breakage detectors, etc.). Door access control mainly includes door opening machine, door access control mainframe, and so on. Electronic patrol system has online and offline type, the host can use ordinary PC and professional software, patrol stick, IB button (placed in the patrol route everywhere). Emergency call includes call button, pair into the equipment, host and so on. TV monitoring currently has digital and traditional analog system, digital because of the limitations of the current computer technology, mainly used for digital storage, that is, digital hard disk recorders, small systems can be embedded systems, using a professional computer operating system, than the current ordinary computer operating system is more stable and convenient. Large systems mostly use analog equipment, the center uses a matrix to control the input and output of display and storage devices. Compared with the digital system, the center of the equipment, including the matrix also includes professional long-delay video recorders, field switchers, video switchers. There is basically no difference between the two systems front-end equipment, are used in various types of cameras (fixed, with PTZ, dome, etc.).
Question 6: the type of security monitoring PTZ According to the use of the environment is divided into indoor and outdoor type, the main difference is that the outdoor type of sealing performance is good, waterproof, dustproof, load. According to the installation is divided into side mounted and suspended, that is, the head is mounted on the ceiling or mounted on the wall. According to the shape is divided into ordinary and ball type, ball head is the head is placed in a hemispherical, spherical shield, in addition to prevent dust interference with the image, but also hidden, beautiful, fast. In the selection of the head to consider the installation environment, installation methods, operating voltage, load size, but also to consider the performance-price ratio and whether the appearance is beautiful.
Question 7: PTZ voltage AC24V auxiliary voltage DC12V is what it means is that the input is the main AC 24-volt voltage, when the external power supply fails, this time the best will have to use the auxiliary power supply that is the backup power supply, you can use DC 12-volt power supply directly to him, in fact, AC 24-volt input to the inside of the circuit rectifier step-down for DC 12-volt
The head is not only a good choice, but also a good choice for the future of the world's most important products.
Question 8: What are the benefits of a surveillance camera with a PTZ? Is it expensive? Thousands of brands Price varies greatly depends on the practicality of the main miscellaneous brands is not necessary than the price of the main function of the camera is to fix the camera if you need to watch the scene outside the place need to manually adjust the direction of the function of the head is to control the camera up and down, left and right one hundred and eighty degrees of choice can be zoomed to more supportive parameters for the camera to carry out the parameters how many times the zoom, such as Hikvision, one thousand and seventy-eight, "the price of purchase," one million three hundred thousand ball technology can be zoomed to one hundred and fifty of the ball technology. Can zoom to one hundred and fifty building windows and binoculars almost
