Common Problems and Solutions When Installing Surveillance Cameras

Network surveillance camera has entered every aspect of our life, and it has been greatly popularized in modern society because of its convenient installation and low price. During the camera installation process, there are many problems that need attention. The following editor briefly introduces six problems and solutions.

Surveillance camera installation:

• 1. Wiring problem
  The first is the layout of the network camera installation, which is the same as our analog camera. The coverage of the camera is designed according to the area and the distribution of the building, and the monitoring of dead spots is minimized. After the location is determined, we will talk about the wiring problem. , When wiring, we only need to treat each network camera as a computer to lay out the local area network. If we use standard network wiring methods to wire, there will be no problems.
• 2. How to determine whether to use a 100M switch or a Gigabit switch
  This is determined by the number of IP cameras and the code stream. The code stream of a 720P IP camera is about 3M, that of a 960P camera is about 5M, and that of a 1080P camera is about 8M. If one of your switches is a 24-port 100M switch, Then you can connect up to 24 720P machines, 24*3=72M, generally we use 80% of the data flow of the switch is already the limit. For more than 24 720P machines, it is recommended to use a 1000M switch and a Category 6e backbone network cable.
• 3. Select the network cable
  There are tricks in choosing a network cable. No matter how good the network cable dealer is, we must be sober when choosing a network cable. Take a multimeter with you when wiring. The whole box of 300-meter wires, the resistance of a single wire at the end of the wire, and no more than 30 ohms are considered good products.
• 4. Necessary tools for network camera installation and network detection
  A good wire crimping pliers, ‘If a worker wants to do a good job, he must first sharpen his tools’; a reliable wire tester (preferably with a wire finder); a good wire cutter, which can help Very helpful, it can help you increase the success rate of crimping to 99%; the network detection method, the PING command under DOS must be used; there is also IPCONFIG; of course, you must bring a notebook and change the IP when doing network camera projects , Change the network segment, and check the route without him. If conditions allow, it is best to prepare an extra 3G/4G network card-now smartphones can also be used as Internet hotspots. When there is really no other way, you can directly contact the manufacturer’s technology and let them provide remote assistance. It is best to have a notebook when installing and debugging the network hard disk video recorder.
• 5. What should I do if the network wiring exceeds 100 meters?
  Provide several ideas:
  1. Adding a switch in the middle can extend 100 meters, but it is best not to exceed 200 meters;
  2. Optical fiber is the most reliable long-distance transmission equipment. If you are far away, use optical fiber as much as possible, from 100 meters to 20KM!
  3. 100 meters to 3KM If the site is open, you can use an outdoor directional high-power AP bridge for docking.
• 6. Why can’t the distance between the installed camera network cable be only about 30 meters?
  If the network camera device itself is not faulty, there are generally two situations:
  ①It is the use of low-quality network cables, poor materials for network cables, and poor winding technology, which have been mentioned above and will not be elaborated;
  ②It is the wrong way to make the thread. This is a common problem for many novices. “My thread is connected with a thread tester, all 8 lights are flashing, and the thread sequence on both sides is the same.” Brother, please stop , using the standard 568B wiring method, you can keep your distance worry-free.
