What are the requirements for the installation of the security monitoring system

Install the camera: Install the camera in the selected location as needed. Make sure that the camera can provide clear images and a wide field of view. Connect the camera and monitor: Use the correct type of cable to connect the camera to the monitor. Make sure the connection is stable and test whether the image transmission is normal.

Installation angle: mainly divided into two types: cylinder type and hemispherical type. Among them, the cylinder type is relatively common and can be used indoors and outdoors; the hemispherical type is generally used indoors, with a small volume and can be installed on the wall or ceiling.

A network cable needs to be installed for the surveillance camera. Installation monitoring environment: small household monitoring: generally adopts wireless connection method. The biggest advantage is that the installation and debugging are simple, which can avoid tedious construction wiring, and it is very beautiful!The premise of adopting this method is that the WIFI signal strength in the local area of the installation area must be good.

The equipment of the security system is required to be installed in a clean air-conditioned room and installed on the standard rack of 19. Appropriate space should be left between the equipment, and forced ventilation fans should be used.

In the environment of strong electromagnetic interference, the installation of surveillance cameras should be isolated from the ground. Under the condition of meeting the requirements of the field of view of the monitoring target, its installation height: indoors should not be less than 5m from the ground, and outdoors should not be less than 5m from the ground.

Installation steps of wireless camera monitoring system

After installing the driver system and installing the camera in a good viewing position, you need toIt is connected to the computer system. At this time, the computer should be turned on and the driver system of the camera should be installed. If the wireless camera you bought is driver-free, then omit this step.

The use of the webcam is very simple. Considering the actual situation, just install the lens correctly, connect the communication cable, and turn on the power supply. If the lens is not installed correctly and the state of the camera and lens is not adjusted, it will greatly affect the performance of the system and fail to achieve the expected effect.

When installing indoor monitoring, first select the installation location, pull the wire used for monitoring installation, and then select the surveillance camera. After purchasing the camera, you can ask an electrician to help you install it, or you can install it directly according to the installation instructions.

The video tutorial for installing surveillance includes the following steps: Steps1: Prepare the required materials and equipment - surveillance camera - computer or surveillance equipment - network connection Step 2: Install the surveillance camera - install the surveillance camera in the appropriate position of the required monitoring area to ensure that the camera has a good field of view.

The installation steps of the home security monitoring system are as follows: Set the monitoring area: Determine the area that needs to be monitored in the home, such as the front door, back door, garden, etc., and select the appropriate number and location of monitors.

Step 4: Network Configuration Select the camera device in the APP or client and click the "Settings" button. After entering the device settings page, click the "Network Settings" option. According to the requirements of the network environment, select wired connection or Wi-Fi connection and make corresponding settings.

What is the difference between surveillance and camera

The difference between surveillance and camera lies in the scope of function and application. Monitoring refers to the process of real-time monitoring, recording and management of specific areas or objects through the use of various technical means. It covers a variety of equipment and systems, including cameras, video recording equipment, sensors, alarm systems, etc.

Different properties Wide-angle camera: It is a camera with a viewing angle of more than 120 degrees. Ordinary camera: refers to the camera of HD1080P or HD960P or HD720P.

The visual range is different, the monitoring is 8mm, the visual range is within 90 degrees, the monitoring is 4mm, and the visual range is within 70 degrees. The monitoring distance is different.The monitoring distance is 8mm, the monitoring distance is 4 meters, and the monitoring distance is 4mm, and the monitoring distance is 6 meters. The imaging is different.

The biggest difference between surveillance cameras and ordinary cameras is the difference in the effect of use. In order to cope with security, surveillance cameras need to be controlled remotely and monitor the target continuously for a long time. At the beginning of the design, it was determined that its environmental adaptability was higher than that of ordinary cameras.

It is a system, and the camera is a major component of this monitoring system. In this sense, cameras and surveillance are subordinate, and cameras are not equal to surveillance. In reality, only the camera cannot play a monitoring role. It must transmit and make errors in the ingested signal to play a monitoring role.

What equipment is the monitoring system mainly divided into

1. The monitoring system is mainly divided into four categories: front-end equipment, transmission equipment, master 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.

2. Front-end equipment: camera (network type, hemispherical type, pinhole type, standard gun type, integrated type, industrial type, etc.). Camera lens (focus, manual zoom, automatic aperture, electric zoom, etc.). Camera protective cover (ordinary gun type, ball type, hemispherical type, waterproof type, explosion-proof type, universal type, etc.).

3. Camera, lens, gimbal, intelligent spherical camera. Video transmission system: transmission cable, optical fiber transmission, common cable transmission, twisted pair transmission, wireless transmission, power carrier transmission, etc., terminal display system. DVR hard disk recording system, IP-SAN, video matrix, picture processor, switcher, distributor.

4. The protective cover is also one of the most commonly used equipment in the monitoring system, and its main functions are dustproof and anti-vandalism.The sealing performance of the outdoor protective cover must be good to ensure that rainwater cannot enter the interior of the protective cover and erode the camera. Some outdoor protective covers are also equipped with exhaust fans, heating plates and wipers, which can better protect the equipment.

5. The surveillance camera is the core part of the monitoring system. It can transmit the images of the monitoring area to the video recorder in real time. A video recorder is a device used to record surveillance images, which can record images transmitted by surveillance cameras.
