As a new generation of security people, they deal with surveillance and access control all day long, and of course, Party A's grandfather has developed a strong body and a skill of observation, that is, Party A's grandfather says that we minions have to do it. There is basically nothing to resist. In order to earn money to support the family, we have to carry everything on our own. Hey, if we talk too much, we will cry.

Speaking of business, I recently took a small job, saying that it was not a small job, that is, to install a camera for the temporary duty stations on the three hills. In fact, it was a simple thing to install the camera. I also surveyed the place and went to set up a pole. As soon as the camera was hung up, and it was confirmed that there was still electricity at the scene, they had already pulled up their own cooking for convenience, and the biggest problem was that there was no net, which could not be monitored in real time without a net. My earliest suggestion is to install a NVR at each point and store it in NVR, but Boss Zhao of Party A means that if this cannot be monitored in real time, it doesn't make much sense to install monitoring. In other words, the monitoring project cannot be carried out if the data cannot be transmitted to the head office down the hill in real time.

There is no way, in order to take the order and continue to think of a way. I searched the method on the Internet and consulted the opinions of other colleagues.

Some suggest pulling the optical cable directly, which is the safest, but the cost is too high. I probably calculated that it would be pulled to three points from the head office at the foot of the mountain. Except for some places where the optical cable coincided, the optical cable was calculated to be nearly 5 kilometers. According to 20 yuan per meter of contracted labor, this is almost 100000, and Party A's budget is only how much, which is not considered directly.

Some people recommend the wireless bridge, which was originally the first plan I thought of, but the scene environment does not allow, the house is not on the top of the mountain, the bridge can not be crossed, I can no longer pull the cable to the top of the mountain to relay the wireless bridge, which is not realistic.

A buddy recommended Zero Dun's 4G video gateway. Compared with the above two schemes, it seems to be the simplest one. As long as you power the equipment and plug in a sufficient amount of traffic card, you can connect the camera to the network with the head office at the bottom of the mountain. !

So, I immediately purchased two sets for testing, and began to use them that day, point-to-point configuration, one next to the monitoring, one in the office, and one button in the management system of Zero Dun, so I simply completed the connection and started running for a few days. The network speed of 4G is OK, and it's okay to have two cameras.

So the small project was soon completed, and Boss Zhao of Party A was also very happy, saying that I took the trouble to ask someone else to quote the price to pull the fiber optic cable, which was more than 80,000 higher than my offer. If you add a camera, you will come to me again.

This time, thanks to this zero-hidden 4G video box, the small box has played a huge role in completing the remote monitoring of the video without the network. It goes without saying that only writing can express it, do not spray it if you don't like it!
