Seeing this black thing, Xiao Jing's heart suddenly chuckled and almost jumped out, this is the infrared night vision camera known as the top of the black technology of the Senate. These cameras have been arranged when the construction of each guest house is planned, and the location of the guest house, there are strict requirements for how many presidential suites there are in a guest house, and the height of the presidential suite and the distance from the staircase are also limited, because it cannot be too far away from the transformer. These monitoring network cables and power supply cables are brought from the old world, is a special supply of materials with one millimeter less than one millimeter, in the construction period is required to reduce construction losses as much as possible, and even when making wires, it is required to peel off the skin of only two centimeters from the network cable at most. In order to install and conceal these surveillance cameras, it took a lot of effort from the counterintelligence department to complete the installation of these guest house suite cameras after a lot of effort.

Each monitoring unit is composed of a camera and a pickup, and it can also record synchronously when recording to ensure that important information is not missed during monitoring. The power supply part almost makes the installer worry out of the dog's brain, monitoring is the need for electricity, but in the case of the current power outage in the Oriental Port, it is basically an impossible task to ensure the 24-hour continuous power supply in the port area, so the monitoring of electricity can not rely on the power department alone. After many discussions and compromises between the Industry Committee and the power department, it was finally decided to install more than a dozen solar panels and six wind turbines next to the Port Authority's transformer near the guest house.

There are only two computers in the Port Authority, but there are several switches, and the data here is not only transmitted back to the database at Bunker Hill, but also to the counterintelligence unit's computer room at the National Police headquarters. The use of network cables for such long-distance transmission without fiber optic transmission really caused several veterans of the communications technology department to almost crash. The transmission capacity of the network cable can not meet the needs of this kind of distance of three or four kilometers, and it is not impossible to use wireless transmission, but there is a huge problem, that is, the wireless is very seriously affected by the weather and blocking obstacles. At the beginning of the year, when the northbound detachment went deep into the mainland, the wireless transmission equipment used could be used, but it could only transmit Morse code such as dots and lines, and although it could be used to transmit data communication in a certain sense, the speed was outrageously slow, and even a mobile phone news push sent from Dongfang Port had to take more than a minute to receive it, and if you wanted to watch the news, you had to stand next to the transceiver for six or seven minutes to see one. It is conceivable that with such a rate to transmit large-scale data, just waiting for these veterans to go crazy. But no matter how worried the veterans of the communication technology department are, the problem is the problem and will not solve it by themselves, so Li Zhe can only find a way to solve this problem with his own strength.

During the crossing, Li Zhe once proposed to bring optical fiber transmission equipment to ensure long-distance transmission, but was directly rejected, because it was envisaged that the entire Senate and various departments were concentrated in the administrative area, and there was no need to use expensive optical fiber, and the network cable was enough to meet the needs. However, as the port of Orient grew larger and larger, the administrative area was moved to Bunker Hill, but the port authority and the Ministry of Commerce and trade could not move with them, so the communication here became a problem, and the data transmission used for monitoring could not meet the needs.

Fortunately, the veterans of these crossings are basically highly educated, especially the veterans of the communication technology department have special skills in related professions, and after a few weeks of discussion, they made a decision that made Xiao Jing, who was in charge of approval, almost drop his jaw - dismantling a switch.

They dismantled each chip of the switch, analyzed the wiring and the circuit of the chip according to the above, drew a detailed circuit diagram, and then simulated the circuit through a computer program, and finally trial-produced a large "switch" after hundreds of experiments.

The size of this switch is quite large, in fact, in general, the network port transmission capacity of a switch has been amplified, of course, they are no longer ordinary eight-core twisted pair network cables, but eight thicker iron wires. Of course, the electricity used in it is naturally through the amplified current, not the weak current used by the switch network port. In order to ensure the normal data transmission and transmission, this switch consists of two network ports, one is responsible for sending and the other is responsible for receiving, and finally converts into digital signals and returns to the network port of ordinary switches. According to tests conducted by the communications technology department, this long-distance transmission switch is capable of transmitting about 10 kilometers without attenuating the signal, and the speed can still reach the gigabit transmission rate.

But now Xiao Jing looks at the camera in Milo's hand, but he doesn't have the slightest pride in developing new technology - your sister! Isn't this thing hidden installed? How did it fall out? And was found in the princess's bedroom? It's a camera! If it is discovered, then the reputation of his side will be ten miles away from the wind - peeping at the woman and recording the image, this is simply ......

He still had a headache in his head, but he heard someone behind him say, "Oh, why did the heater fall out again?" ”
