How to use the security monitoring system

Set up remote access: If you need to remotely access the monitoring system through mobile phones or computers, you need to set up network port mapping or use cloud services.Improve other accessories: Other accessories can be installed as needed, such as infrared sensors, door and window sensors, etc., to enhance the function of the home security monitoring system.

Connect the surveillance camera and monitor (computer) with a video cable to the network hard disk recorder, and you can successfully build a home security monitoring system. The rest is to be familiar with the operation.

Wired connection first connects various lines of the wired surveillance camera to the computer and the power supply. And connect to the wireless router. When using the browser to access the camera, you need to install the plug-in first to preview the image of the camera.

Usually, we have two control methods - analog control and digital control. Analog control is an early control method, and its console is usually controlled by the controller orThe analog control matrix composition is suitable for small partial security monitoring systems. This control method has a low cost and a small failure rate.

What are the requirements for the installation of the security monitoring system? What are the basic equipment selection requirements? First of all, determine whether to install a monitoring card on the existing computer or use an embedded hard disk recorder as your monitoring host.

What is an intelligent security system?

Intelligent security alarm system The home security alarm system is commonly divided into outdoor three detection and induction: it is composed of an alarm host and multiple three detectors, with infrared, microwave induction, intelligent logic analysis and other triple induction protection, and can be linked with intelligent control systems such as lighting.

Simply put, intelligent security is the optimization and expansion of traditional security protection systems.

Intelligent security system can be simply understood as: a technical system for accurate and selective operation of image transmission and storage, data storage and processing. In terms of intelligent security system, a complete intelligent security system mainly includes three major parts: access control, alarm and monitoring.

What parts does the security monitoring system include?

The security monitoring system is mainly composed of these three parts: front-end part: mainly composed of black-and-white (color) cameras, gimbals, protective covers, brackets, etc. Transmission part: use coaxial cables, wires and multi-core wires to transmit audio, video, control signals and AC and DC power supply, etc. by overhead, buried or along the wall.

The hardware composition of the security monitoring system usually includes the following aspects: Camera: Installed in the area that needs to be monitored, and the monitoring is completed by capturing images. Video server: used to manage and store images or videos taken by cameras.

Four parts, as follows: Image monitoring function: (1) Video monitoring adopts various cameras, switching control host, multipleScreen display, analog or digital recording devices and lighting devices can effectively monitor the internal and external parts. The monitoring parts include key departments, important facilities and public activity places.

We divide the entire security monitoring system into seven layers according to the different functions of each part of the system - performance layer, control layer, processing layer, transmission layer, execution layer, support layer and acquisition layer. The composition of the monitoring system - the performance layer performance city is what we feel most intuitively, which shows the quality of the whole security monitoring system.

It is generally divided into three major parts: First, the front-end part (including camera, lens, gimbal cover bracket, etc.), mainly the image acquisition equipment and related auxiliary acquisition equipment. Second, the intermediate transmission part. It mainly transmits signals, such as twisted pair transmitters, optical terminals, repeaters and amplifiers and other transmission equipment.

The security system is mainly divided into 5 parts. The first part is the perimeter alarm system. Part 2 is the video surveillance system. The third part is the visitor intercom system. Part 4 is the household alarm system. Part 5 is the electronic patrol system.

What are the community security systems

1. The security systems are as follows: Emergency Broadcasting System Emergency Broadcasting System In 1997, the system was Emergency Alert Syste M, EAS) replace. Building intercom system The building intercom system is mainly composed of host, extension, UPS power supply, electronic lock and door closer, etc.

2. What are the surrounding anti-crossing alarm devices in the community security system? Install various detectors around the closed community to prevent illegal intrusion.In order to ensure the personal safety of residents in the residence, the residential alarm device installs various detectors indoors for monitoring and provides emergency call function.

3. Gas fire protection system (5) Digital monitoring system (6) Digital patrol system (7) Parking lot management system (8) Perimeter alarm system (9) Elevator five-way alarm system (10) Key centralized management system In terms of classification and subordination: the security system includes: ( 1) Power environment monitoring subsystem.

4. [Answer]: video surveillance system, intrusion alarm system, patrol system, entrance and exit (access control) control system, parking lot (warehouse) management system and visitor intercom system.

Security System Security System ConstructionSet-up scheme

1. The electronic patrol system (guard tour system) refers to the electronic system that manages and controls the patrol route, method and process of security patrol personnel.

2. Build a complete, integrated, reliable and easy-to-operate security system, so that it monitors and manages the entire building as an organic whole, and connects to the intelligent management system of the building. This is an important goal for the establishment of a security system.

3. Community entrance and exit construction; community internal construction; community intelligent security system. By building these three aspects, the community has formed a security ecological chain, and each system is interlocked. Once an emergency occurs, it can be linked to respond quickly.

4. Install the camera system: Installing the camera system is one of the important means to protect home security. You can choose to install wired or wireless cameras and remotely monitor the security of your home through mobile devices or computers. Install access control system: Access control system is another effective way to protect family safety.

5. The security system is as follows: Emergency Broadcasting System Emergency Broadcasting System was replaced by Emergency Alert System (EAS) in 1997. Building intercom system The building intercom system is mainly composed of host, extension, UPS power supply, electronic lock and door closer, etc.

6. Identification management subsystem The community access identification management subsystem is mainly used to confirm the management of residents and owners entering and leaving the community, including personnel access and vehicle access management.At present, in general, high-end communities use contactless smart card radio frequency cards as identity cards, and both personnel and vehicles use the only valid identity card.
