As people's awareness of safety precautions has increased, our lives have been largely incorporated into various monitoring measures. In the public areas where we live, parking lots, supermarkets, banks, etc., the cameras have already everywhere. So how do you install and debug the surveillance camera? Let's share the little technology of the general surveillance camera from installation, wiring, to debugging!
First, the installation of surveillance cameras
1. The installation height is generally 2.5m~4m, and the outdoor is generally 3.5m~4.5m. Other special occasions are treated, such as elevators and open plazas.
2. When installing, you can adjust the angle according to your own naked eye, which may reduce the workload of adjusting the position angle in the later stage.
3. Take lightning protection measures when installing outdoors to better protect equipment.
4. Areas with strong electrical equipment should be avoided as much as possible to reduce interference.
5, try to avoid the camera direct light source when installing.
6, there is one to pay attention to the details, be careful not to touch the lens with your hand, in order to soil the lens, causing the back-end display part of the monitoring picture is not clear.
Second, the surveillance camera wiring
1. When wiring the power cable used for equipment power supply, we must consider the distance of the distance, the loss of voltage, and select the cable with the appropriate wire diameter to avoid the rework wiring caused by insufficient voltage and too much loss in the later stage.
2, network cable wiring should pay attention to the camera to the transmission equipment distance must be kept within 100m, in order to ensure the normal transmission of the signal, beyond the distance must use fiber optic cable wiring, try not to adopt the switch cascade.
Third, the monitoring of the surveillance camera
1. When debugging the connection, the transmission device should select the device according to the number of devices, such as the choice of 100M switch and Gigabit switch.
2. Check the line before commissioning, and the power supply wiring is good.
3. In the debugging, different functions should be turned on for different screens to achieve better monitoring effects, such as: wide dynamic, strong light suppression, backlight compensation and other functions.
4, the change of the screen name, the adjustment of the preview layout helps to be more intuitive and better to watch.
5, the system is well debugged, you can run normally, but you should pay attention to: regular system maintenance.
English referred to as ICD, full name Industrial Communication Device. This
section will introduce the wired communication equipment and wireless
communication equipment applicable to industrial control environment in a
comprehensive way. Wired communications equipment
to address the industrial field of serial communication, professional
bus-based communications, industrial Ethernet communications and various
communication protocols between the conversion equipment. Wireless
communication equipment is mainly wireless AP, wireless bridge,
wireless card, wireless lightning arrester, antenna and other equipment.
