The video surveillance system is used in conjunction with the network camera. It can be connected to the network by wired or wireless connection, which is easy to install and deploy. It does not require additional configuration of dedicated computers and video recording equipment. The user can use the computer as a monitoring terminal device, and can receive alarm information and view monitoring video anytime and anywhere. It is stable, reliable, economical and practical, and can be used for fire prevention, security, personnel monitoring, remote management, etc.
Precautions before installing the wireless monitoring system:
1. Get monitoring. Do not rush to the site to install, first debug in the machine room and then install, check the equipment accessories are complete. The installation of the wireless monitoring system first determines whether the existing computer is equipped with a monitoring card or an embedded hard disk recorder as your monitoring host. The use of a computer to install a monitoring card, the overall investment is relatively low, suitable for familiar with computer installation, professional staff, more functional requirements. The computer needs to be turned on 24 hours; the use of the embedded DVR does not require professional knowledge, no need to be on duty, and the operation is very simple, as easy as using a VCD.
2. To install the monitoring device, you need to determine how many cameras to install and determine the monitoring range and image quality of each camera. First determine the number of cameras to be monitored, and then determine the lens monitoring range of the camera according to the specific situation: the distance from the camera to the monitoring point and the area to be monitored must be clarified. As for the definition, we think that the camera of 480 TV line is enough.
3, whether you want to have night vision function. If your monitoring equipment is installed in corridors, foyers, aisles, warehouses and other places where the light is dark, you can consider the infrared night vision function of the camera, it should be noted that the infrared camera in addition to professional night vision In addition to the special order, the infrared camera also needs to have a light-assisted five-finger on-site, and the infrared distance will be shortened. If the scene is a garden lawn, the infrared effect is even worse.
4. Is it direct wiring or wireless transmission to install? In addition to the expensive price, the wireless network does not save the trouble and unsightly of the camera installation, but needs to pay attention to the distance and obstacles. In principle, cement building materials will shorten the wireless transmission distance, metal materials will completely block the wireless signal, and the transmitter (at the camera end) and the receiver (at the host end) should be away from other electrical appliances to avoid interference. If wireless network is used, It is necessary to have monitoring equipment that is more than twice the price. We recommend using wired transmissions to install unless necessary.
5. On-site monitoring and network monitoring When determining the installation of the monitoring system, you should consider whether you need network functions. That is to say, if you need to monitor and control the monitoring site at any time on the Internet, you need to select the monitoring host with network function. Avoid installation but no network transfer.
Surveillance camera installation method:
(1) Debugging equipment
1. Prepare 4 network cables, 1 switch, and 1 porous socket.
2, start connecting devices
3. The adapter's Internet port of the central station device is connected to the switch with a network cable.
4. Connect your computer to the same switch (if the IP of the dome is the same as the LAN IP, as long as the computer is in the LAN)
5. Start connecting the power cord.
6. Check that the previous connection is correct and start energizing the device.
7. If everything is normal, we will see that the signal light here is basically full.
8. Enter the dome IP on your computer. If you can open the monitor screen, it means everything is normal. This is the end of debugging.
(2) Site selection
1. Select the installation location according to the requirements of the engineering company.
2. It is necessary to see if the site location is convenient for construction and installation.
3. Pay attention to whether there is a tall building near the location of the machine room.
(3) Preparation before installation
1. According to the installation location of the site, whether the existing resources on site can be used for installation. If there is no condition to directly install and find leadership communication, find the relevant unit to weld the bracket in time.
2. Prepare tools. Live wrench, Phillips screwdriver, slotted screwdriver, cable, crystal head, cable clamp, vise, multi-hole socket, etc. (prepare the actual required tools according to the specific situation).
(four), start installation
Step 1: Install the central station equipment. The central station should be installed near the equipment room. After the installation is complete, connect the line and power it on.
Step 2: Install the remote antenna.
1. First take the power at the scene.
2. Power on the antenna, the ball machine can be powered off first.
3. By adjusting the orientation, you can see if the antenna has a signal, and the signal strength must be more than 3 grids.
4. Fix the bracket, dome, dome, antenna, and waterproof power box.
5, check the connection to pay attention to waterproof.
(5), trial run
All devices are powered on and start trial operation. Pay attention to check whether the picture is smooth and clear. Observe 1-2 days. If everything is normal, monitor the IP address and hand it over to the headquarters.
(6), matters needing attention
1, pay attention to safety
2, the construction site must bring a helmet
3, all equipment pay attention to waterproof fire and electricity safety
4. Do not have obstacles between the remote antenna and the base station.
5, all antennas are required on one side, not required on one line
6, on-site power requirements to ensure that the power supply is normal (24 hours of continuous power)
