The security monitoring system uses optical fibers, coaxial cables or microwaves to transmit video signals in its closed loop and constitutes an independent and complete system from the camera to the image display and recording. It can reflect the monitored objects in real time, vividly and truly, which not only greatly prolongs the viewing distance of the human eye, but also expands the capabilities of the human eye. It can replace the artificial long-term surveillance in a harsh environment and people can see it. Everything that actually happened at the monitored site was recorded by a video recorder. At the same time, the alarm system equipment alarms the illegal invasion, the generated alarm signal is input to the alarm host, and the alarm host triggers the monitoring system to record and record.
<br> <br> distal tip portion of the complete analog video imaging, the detector generates an alarm signal, PTZ, control of the shield, the alarm output functions. Mainly include: camera, power zoom lens, outdoor infrared detector, dual detector detector, temperature and humidity sensor, head, protective cover, decoder, BSV LCD splicing screen, digital scanner, warning lights, siren and other equipment ( Equipment usage is configured according to the actual needs of the user). The camera uses the built-in CCD and the auxiliary circuit to shoot the scene as an analog video signal, which is transmitted via the coaxial cable. The power zoom lens zooms in and out of the shooting scene, and realizes optical adjustment such as aperture and focus adjustment. The temperature and humidity sensors can detect the temperature and humidity in the environment so as to ensure a good internal physical environment. PTZ, protective cover provides a suitable working environment for the camera and lens, and can achieve horizontal and vertical adjustment of the shooting angle. Decoder is the core equipment of PTZ and lens control. Through it, it can realize the use of computer interface through software control lens and PTZ.
The transmission part of the transmission portion <br> <br> presented here is composed mainly of a coaxial cable. The transmission part requires real-time transmission of images captured by the front-end camera. At the same time, it requires transmission with small loss and reliable transmission quality. Images can be clearly displayed in the video control center.
<br> <br> control section which is the core of the security monitoring system, which monitors the completion of data acquisition of analog video signals, MPEG-1 compressed data recording and retrieval monitor, hard disk recording and other functions. Its core unit is the acquisition and compression unit. Its channel reliability, calculation processing capability, and convenience of video retrieval directly affect the performance of the entire system. The control part is the key part to achieve linkage between alarm and video recording.
TV wall display section <br> <br> the partially completed retrieve real-time monitoring and playback signal display and video content on the system display screen or monitor. The system supports multi-screen playback, simultaneous recording of all channels, system alarm screen, and voice prompts. It is compatible with the unobstructed monitoring function of the traditional TV surveillance wall, which greatly reduces the work intensity of the on-duty personnel and improves the reliability of the security defense. The terminal display part actually completed another important task - control. This control includes the camera pan and tilt, lens control, alarm control, alarm notification, automatic, manual arming, anti-theft lighting control and other functions, the user's work only need to click the mouse on the desktop to operate.
Part of the anti-theft alarm <br> <br> important entrances and exits, stairs install active infrared sensor, arm, installed alarm host monitoring center duty room (control room), someone somewhere once more into the probe that is auto-sensing, trigger Alarm, the host shows the alarm location, and the corresponding searchlight and camera are linked simultaneously, and automatically switches to an alarm camera screen on the host computer. The alarm center monitoring computer pops up the electronic map and makes an alarm record, which prompts the on-duty personnel to handle and greatly strengthens the security. The alarm defense system uses active infrared motion detectors to control important channels and connect them to the alarm center of the management center. When personnel enters from abnormal entrances during non-working hours, the detector will send alarm signals to management immediately. At the same time, the center initiates linkage devices and equipment to warn intruders and can perform continuous video and video recording. Electronic barriers are installed at the periphery of the building. The electronic fence is the most advanced perimeter security alarm system. It consists of a high-voltage electronic pulse master and a front-end detection fence. The high voltage electronic pulse master generates and receives high voltage pulse signals and generates an alarm signal when the front end detection fence is in contact net, short circuit, and open circuit state, and sends the intruder signal to the security alarm center; the front end detection fence consists of rods and metal wires, etc. The tangible perimeter of components. An electronic fence is an active intrusion prevention fence that counters an intrusion attempt, repels an intruder, delays the invasion time, and does not threaten human life. It sends the intrusion signal to the security department monitoring equipment to ensure that the management personnel Can understand the situation of the alarm area in time, and quickly handle it.
<br> <br> power supply system for the supply of the closed-circuit monitoring to ensure normal operation of the entire alarm system plays a crucial role, i.e., once the damaged power will cause the entire system is paralyzed. The power supply of the system can be divided into two parts: centralized power supply and distributed power supply. Users can choose according to actual needs.
The above is only a typical security monitoring system introduction. In practical applications, there will be different types of solutions. Security monitoring system solutions will generally be tailored according to the different requirements of users.
Power Line Surveillance Camera
The monitoring camera based on power line transmission is a technology that transmits the monitoring image captured by the camera to the monitoring center through ordinary alternating current. This technology will greatly reduce the construction and operating costs of the use unit. The power line transmission camera has only one lead-out line, that is, the power line. This power line not only provides power for the camera but also provides transmission of video signals, audio signals, and control signals. The transmission distance can reach 1,000 meters and over 1000 meters in the available repeaters. Following. We can use the existing power lines in the interior to set up a video surveillance network, which has the advantages of no need to lay cables and convenient maintenance. It is plug and play, efficient and stable, and environmentally friendly, allowing any camera with an outlet to monitor. It avoids a lot of engineering construction necessary for laying cables and is plug and play. It is a wired monitoring method without wiring, and it does not affect interior decoration. It is also very simple to maintain and upgrade in the future. In addition, it makes full use of the existing network of indoor power line networks to allow wires to transmit data while transmitting power. It is a wired monitoring method that does not require additional wiring. No matter what office location can monitor any camera, anytime, anywhere monitoring, it also greatly saves the wiring cost of building and expanding the network and avoids the damage to the existing building layout.
