What does a home monitoring system consist of? Ryoko began to introduce these devices, which can be installed by themselves.

This is very simple, surveillance cameras are worth a penny, you want to get good goods cheaply, you are waiting to be slaughtered by the dealer, in short, this aspect is true of the false, I am a surveillance wholesaler in Guangzhou, if you want to consult this area, I can teach you how to distinguish the performance of the camera and the clarity of the product.

Hello, a complete monitoring system mainly includes:

1. Front-end equipment: cameras (network type, hemispherical type, pinhole type, standard gun type, integrated type, industrial type, etc.).

2. Transmission equipment: optical fiber.

3. Control equipment: DVR or capture card, etc.

Fourth, the display device: the monitor or the splicing screen.

The surveillance system is generally composed of a front-end camera and a back-end software system.

Cameras, lenses, pan-tilts, smart dome cameras. **Transmission system: transmission cable, optical fiber transmission, common cable transmission, twisted pair transmission, wireless transmission, power carrier transmission, terminal display system.

Surveillance does not simply refer to the CCTV monitoring system, but the monitoring system in the traditional sense is composed of front-end cameras (including: dome cameras, infrared cameras, all-in-one machines, etc.) plus mid-end equipment (optical transceivers, network servers, etc.) and back-end equipment hosts (hard disk recorders, IP-san, matrices, etc.).

Features of surveillance

1. The monitored image content can be saved in the hard disk, burned in the disc or saved in the backup storage device for use as archival materials.

Second, overcome a lot of human function deficiencies, for example: monitoring equipment can work 24 hours a day.

3. It can realize the alarm function linked with other safety protection systems to find dangers in time.

Monitoring

The monitoring system is one of the most widely used systems in the security system, and now the more suitable construction site monitoring system on the market is the handheld communication equipment, and the monitoring is now the mainstream. From the earliest analog monitoring to the hot digital monitoring in previous years and then to the current ascendant network monitoring, earth-shaking changes have taken place.

In today's gradual unification of IP technology around the world, it is necessary for us to re-understand the development history of the monitoring system. From a technical point of view, the development of the monitoring system is divided into the first generation of analog monitoring system (CCTV), to the second generation of digital monitoring system (DVR) based on "PC + multi-card", to the third generation of monitoring system (IPVS) based on IP network.

In recent years, the development of information technology and the improvement of people's living environment have prompted people's awareness of home security to be unprecedentedly strengthened. The home security monitoring system is a comprehensive prevention system composed of three aspects: human prevention, physical prevention (also known as physical prevention) and technical prevention. Home monitoring system is a kind of home technology prevention, the use of network technology will be installed in the home of the first to take the ante, audio, alarm and other monitoring systems connected, through the central control computer of the town wide management will be useful Yu Min Liang information saved and sent to other data terminals, such as mobile phones, notebooks, 110 alarm center, LCD screen, monitors, etc.

What does a home monitoring system consist of? Ryoko began to introduce these devices, which can be installed by themselves.

Electromagnetic locks are good things that have been tested.

It is difficult to do it at a cost of 300 yuan, unless the boss is very familiar with you, or buys second-hand equipment, but you have to install it yourself, otherwise it is impossible, and there is no profit.

First of all, you say that the distance is 30 meters, whether you are talking about the distance after the bend or the straight line distance, it is recommended that you buy 50 meters (short afraid that it will be troublesome to pick up when it is not enough) monitoring line 75-3, 50 yuan. In order to save costs, the power supply is connected to the nearest plug. Buy a 5 meter 2* power cord, 5 yuan.

Secondly, a camera, 180-200, basically you can get it at this price, the power supply is 12V, 2A one, 20-30. If it's a bolt, you need a bracket, 18, and if it's a hemisphere, you can save this cost.

I hope it will help you.

Viewwell Technology's products are mainly composed of network cameras and VPN network servers, which only need to connect the network camera, VPN box and router when using, without dynamic domain name setting, plug and play to achieve remote monitoring function. The IP camera comes with a wireless connection to wifi, which can be set up as wireless monitoring.

1. Gimbal.

The monitoring system says that the PTZ can control its rotation direction at the remote end through the control system. 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-mounted and hoisting, that is, whether the gimbal is mounted on the ceiling or on the wall.

2. a protective cover.

The protective cover is also one of the most commonly used equipment in the monitoring system, and its function is mainly dustproof and vandal-proof. The sealing performance of the outdoor protective cover must be good to ensure that rainwater cannot enter the inside of the protective cover and erode the camera. Some outdoor shields also have exhaust fans, heating plates, and wipers to better protect the equipment.

3. a bracket. Ordinary camera mounts are simple to install, inexpensive, and varied. Choose different models according to different requirements. Outdoor cameras are installed in special locations, some are installed on telephone poles, some stand on tower cranes, and some are installed on iron frames.

Existing brackets may be difficult to meet requirements and require additional machining or refinement.

4. Monitor.

The monitor is the standard output of the monitoring system, and the image sent by the front end can only be sent by the monitor with the monitor. Some monitors also have audio input, S-Video input, RGB component input, etc., except for the audio input used in the monitoring system, most of the other functions are used for image processing.

8. Screen splitter.

There are four divisions, nine divisions, and sixteen divisions of the picture splitter, which can display the images of multiple cameras on a monitor at the same time, and can also be sent to the video recorder for recording.

8. DVR.

The most commonly used recording equipment in surveillance systems are civilian video recorders and long delay video recorders. The time-lapse video recorder can work for a long time, can record 24 hours (with ordinary VHS videotape) or even hundreds of hours of images, can be connected to alarm equipment, automatically start recording when receiving an alarm signal, and can superimpose time and date.

9. Monitoring and management platform.

With network centralized management and network transmission as the core, the whole process of information collection, transmission, control, management and storage is completed, and it can be built on various private networks, local area networks, metropolitan area networks, and wide area networks, and truly realize monitoring networking and centralized management, and authorized users can monitor the monitoring site in real time on any computer on the network.

10. a disk array.

In large-scale surveillance systems, disk arrays are used due to the large number of surveillance videos and large storage. The disk array is composed of many cheaper disks combined into a huge capacity disk group, and the additional effect generated by the data provided by individual disks improves the performance of the entire disk system.

Cameras, capture cards, DVRs, monitors.

OpManager helps you monitor these system resources on Windows and Linux servers to identify performance bottlenecks in advance. OpManager uses SNMP, WMI, or CLI protocols to monitor host resources and collect data.
