What equipment is there in the monitoring system

1, abbreviated CCTV), typical monitoring The system is mainly composed of five major parts: front-end audio and video acquisition equipment, audio and video transmission equipment, and back-end storage, control and display equipment. Among them, the back-end equipment can be further divided into central control equipment and sub-control equipment.

2. The monitoring system is mainly divided into four categories: front-end equipment, transmission equipment, main control equipment and display equipment. This article will introduce the specific contents of these four types of equipment in detail. Front-end equipment The front-end equipment mainly includes cameras, supplementary lights (2 types of infrared and white light), 12V power adapters, waterproof boxes, etc.

3. The following are some common monitoring equipment names: Camera: used to capture video images, which can be divided into fixed, gimbal, portable and other types. Surveillance video recorder: used to store and manage video data captured by surveillance cameras, which can be divided into two types: network video recorder and digital video recorder.

What does a complete monitoring system include?

A complete monitoring system includes a gimbal, a protective cover, a stand, a monitor, a video amplifier, a video distributor, a video switcher, a picture splitter, a hard disk recorder, a monitoring management platform and a disk array.

What equipment does a complete electrical fire monitoring system generally include? The electrical fire monitoring system should be composed of the following monitoring devices: 1 electrical fire monitoring equipment; 2 residual current electrical fire monitoring detector; 3 temperature measurement electrical fire monitoring detector; 4 Wire-type temperature-sensitive fire detector.

The video surveillance system consists of five parts: front-end acquisition, transmission, control, display and recording.

Monitoring the front end: camera, lens, cover bracket, supplementary light, vertical pole.Camera monitoring transmission: BNC head, video cable, power cable, signal amplifier, anti-interference device, lightning arrester, optical terminal. Monitoring back-end: hard disk recorder, hard disk, matrix, screen splitter, picture splitter, operation desk, TV wall, cabinet.

What are the system advantages of monitoring equipment

1. Use a large number of electronic equipment to replace personnel and appliances to achieve the purpose of monitoring, which greatly reduces the use of manpower and finance. And it is more efficient. It can simulate human monitoring habits around the clock to perform various monitoring tasks, and the data recording time is long, and the data can be retrieved repeatedly for use.

2. Advantages of monitoring comprehensive all-in-one line: the camera is exquisite in size, simple and beautiful in design, suitable for high-end applications, and can complement the exquisite decoration.And its intrinsic performance is more obvious. First of all, the automatic focus function makes the image very clear and realizes fast and accurate real-time monitoring.

3. Network monitoring has incomparable advantages over traditional monitoring: a network monitoring system can be built wherever there is a network. Due to the saving of traditional wiring and line maintenance costs, the installation cost of the network monitoring system is greatly reduced.

4. The main advantages of network video surveillance: efficient remote monitoring. If it is necessary to realize cross-regional remote monitoring, the network video surveillance system should be preferred.

What are the commonly used monitoring protocols

I: Joint agreement: Party B undertakes Party A's closed-circuit television monitoring project according to Party A's requirementsInstall and debug, and ensure that the performance of the system meets the requirements of Party A. The unit name, specification, unit, unit price, quantity and amount of the product shall be subject to the purchase list (see the attached instructions). Party B shall not want Party A to provide fake, inferior or inferior products.

Finally, there is the RTSP protocol. This is a protocol used to control media streaming on streaming media servers, which is mainly used in the field of video surveillance. The RTSP protocol is very important for the stable transmission of monitoring equipment. Fluorite uses the RTSP protocol to improve the performance of monitoring equipment in terms of interconnection.

Onvif is a standard protocol that stipulates the interconnection between network video products. By supporting the Onvif protocol, the camera can communicate with other devices that support the protocol, thus realizing the interconnection between devices from different manufacturers.

Dahua surveillance camera is a common brand, and the price of the product is relatively low. The api protocol is a function used to access the webcam live broadcast or realize real-time preview and playback of videos on the H5 mobile phone terminal.

ONVIF protocol. There are four protocols for the camera: SDK protocol, GB/T28181 protocol, and GENETEC protocol. Among them, only the ANTV camera is the ONVIF protocol.

Among them, the GB/T 28181 agreement is a national standard proposed by the Science and Technology Information Technology Bureau of the Ministry of Public Security, submitted by the National Security Prevention and Alarm System Standardization Technical Committee (SAC/TC100), and jointly drafted by the Ministry of Public Security and other units.

3. After a monitoring system enters the debugging stage, trial operation stage and delivery and use, such and such failures may occur, such as: can'tRegular operation, the technical indicators of the system do not meet the design requirements, the overall performance and quality are not ideal, that is, some "soft problems".

4. What are the common faults of surveillance cameras? PChouse will take you to know about it. The surveillance camera has no image to check whether the power supply is connected, whether the power supply voltage is sufficient; whether the BNC connector or video cable is in poor contact; whether the lens aperture is turned on.

5. Common image interference and its solutions Wood grain interference The occurrence of this interference will not flood the normal image in mild cases, and the image cannot be viewed in severe cases (or even destroys synchronization). There are many reasons for this kind of failure and it is relatively complex.

What software is there in the monitoring system

1. Network Butler Software Network Butler is an enterprise-level computer monitoring software, which can automatically record the screen activity on the computer and set the number of days of video storage. Anqishen Software Anqishen is a computer screen control software, which is relatively cost-effective. If the requirements are not too high, you can consider it.

2. Commonly used: cactio is actually not a monitoring tool, but a tool that relies on SNMP's data acquisition and data presentation. But many people like to use it as a monitoring nagios function: data alarm (alarm function is a special function of Nagios) [fault trigger, fault recovery are available.

3. "Little Wing Butler" is an application that can easily connect telecommunications smart devices., if you want to realize indoor monitoring and watch the camera with your mobile phone, you need to buy monitoring equipment under Telecom, which can be monitored by mobile phone through wireless WiFi connection or wired.

4. Anqishen Software Anqishen Software is a professional and recognizable computer monitoring software. It is divided into network monitoring and local monitoring, and can control the hardware and software of the company's computer in an all-round and full cycle.

5. Spector 360: Spector 360 is a comprehensive computer monitoring software that can be used for Windows and Mac operating systems. It monitors computer activities in real time and records data to the central server. Administrators can use Spector 360 to view reports, filter user activities and control computer usage time.
