One of the monitoring cameras before the installation of what needs to be done?
Installation of the camera before the first to give you the relevant product concepts: camera has a lot of names, everyone's name is not the same, the general user will be called the network camera monitor, monitoring probes, network probes, webcams and other names, but professionally speaking called security network video HD surveillance cameras.
What do you need to consider before you start installing video monitors? Why do you want to install cameras and for what purpose? Camera layout where to achieve the purpose of monitoring, what equipment is needed? What materials are needed?
Two, the monitoring system applies to which industries? Surveillance camera points how to deploy?
2.1, the monitoring system applies to which industries The current widely used popularization of monitoring equipment industry is probably distributed in shopping malls, convenience stores, milk tea stores, private restaurants, small hotels and other industries. Installation of monitoring is initially for security, to prevent product theft, but with the progress of science and technology, the installation of monitoring is not only to do security functions, most of the access to the network guest remote monitoring platform, to realize the remote inspection, customer analysis, operations management, etc., will be more and more front-end video data for the analysis of big data, to provide more information for the operation of the management staff.
2.2, how to deploy surveillance cameras point of installation of surveillance, the main purpose is to better protect our property security as well as the emergence of disputes or disagreements in the event of a good video evidence to restore the scene, so the location of the surveillance camera is very critical. So, in which position to capture the video you want? Let's take a convenience store as an example, how should a convenience store's surveillance locations be selected? First of all, the two parts of the cash register and shelves are a must. Because the cash register is the most likely place of conflict of interest with the customer, in order to prevent disputes better restore the scene; while the shelves can not only watch the goods have not been taken by the sheep, but also timely discovery of the placement of goods and inventory; at the same time in order not to fall into a dead end, the doorway needs to be installed in two, one into the door, a doorway; and then the four corners of the installation of one, to achieve full coverage, no blind spot! The effect of the
Three, do-it-yourself installation of video surveillance systems need to prepare the following materials
1, webcam + camera bracket (according to demand, how many cameras is how many brackets)
Webcam
Wall mounted monitor bracket
Webcam resolution 1.3 megapixels, 2 megapixels, 3 megapixels, etc.; surveillance cameras from the functionality of the monitor bracket
2, network HD DVR (VCR also need to buy a hard disk, the main purpose of the monitoring hard disk is used to store video footage, installed in the network HD DVR. That hard disk selection capacity how to calculate? Assuming you need 4 cameras, each camera H.265 + encoded video 15G per day, 4 cameras * 15G / day * 7 days = 500G hard disk is enough).
Network HD DVR
The main purpose of the network HD DVR is to realize the centralized management of the front-end network cameras, device search, image preview, centralized video recording, video playback and other functions;
3, surveillance camera LCD monitor
Surveillance monitors
Monitors do not have any special requirements, if the cell phone Remote browsing can be canceled if the mobile phone end of the capital investment in the monitor. Through the VGA or HDMI interface connected to the network HD DVR. Display network HD DVR.
4, camera power supply, monitoring power cord
Monitoring camera power supply cable
Monitoring camera centralized power supply
If you buy a surveillance camera with POE function, you can save the above power cord and power supply, direct use of network cable can be.
The power cord is mainly used to transmit 220V AC power to the network camera end and then connected to the DC 12V or AC24V monitoring power supply, power supply for the camera.
5, switch
Gigabit network switch
The main purpose of the switch is to realize the electrical signal forwarding network equipment; for 10 points within the small monitoring project, using an 8-port or 16-port ordinary 100-bit switch can be, if more than 10 points, it is recommended to choose the switch with a gigabit port. Gigabit network switch is non-POE function, if your camera is purchased POE camera, then you need to buy POE switch to achieve the network data and power supply using the same line, the line length up to 90 meters. 6, crystal head
Network Crystal Head
Crystal head is a very important interface device in the network connection, twisted-pair cable through the two ends of the crystal head with the front-end network camera and the front-end network camera and the crystal head. Crystal head and the front-end network cameras and back-end switches are connected together, the practice of crystal head 568A and 568B two standards, the current use of 568B standard.
The correct crystal head production in the arrangement of the wire order at both ends are: white orange green white blue blue white green brown white brown. Remember to use the network cable clamp must be compressed.
7, network integrated cable (a camera budget of 20 meters)
Network integrated cable
Ultra-five network twisted-pair cable
Integrated cable is generally used for non-POE-powered cameras, what is POE do not have to understand, when buying attention can be.
POE-powered type of camera using an ultra-five network twisted-pair cable at both ends of a good crystal head can be plugged in. There is no need to plug another power supply.
Four, video surveillance system do-it-yourself how to install it?
Do-it-yourself installation monitoring connection diagram
First determine the location of the surveillance camera installation, to determine the monitoring of the back-end equipment (hard disk recorders and monitors) to put the location. Then it's time to start the first step of the work wiring.
In the place where the surveillance camera is installed, the camera bracket is installed first. Generally speaking, the bracket is universal, there are also special counterparts, when buying this point to pay attention to.
Prepare the security camera and fix it to the top of the security bracket, tighten it with a screwdriver to fix it. Then it is time to install the surveillance camera, camera installation should pay attention to the positive and negative poles, can not be messed up.
Finally to the terminal of the hard disk recorder wiring, inserted into the hard disk recorder.
The last step is to have installed the equipment, power on, set the hard disk recorder parameters, including modification of the monitoring screen points, set the video recording time, alarm time, etc.
