Dvosmjerni komunikacijski sustav obala-brod, dvosmjerni interfonski sustav brod-zemlja sa 10-15 Mbps ethernet

Shore-to-ship two-way communication system is to set up a wireless high-speed video network communication system on shore and on the boat. It is used to meet the needs of Internet access, video surveillance, and voice communication in the area about 6 do 10 kilometers offshore.

Although our TX900 supports a range of 15 kilometara, the height of the transmitting antenna and the receiving antenna is very close to the sea level. Because there are waves in the sea, these will interfere with the wireless transmission system. If possible, the transmitter and receiver’s antenna must be placed as high as possible.

Pitanja

Boat wireless video transmitter demand

Q: I’m searching for an option to send 4 pieces of 1080HD live stream videos over wireless without the internet. It must be a smooth picture and I will install it on a boat. Boat to boat so it will be moving and I must be able to be 360 degrees around. Imate li kakvih prijedloga?

A: Ako 4 IP cameras are on the same ship, we can connect them to the same transmitter through the network cable and a network switch. Their 4 cameras will have 4 IP addresses and share a network transmitter.

Our two-way broadband network transmission equipment based on the IP interface supports a maximum rate of 30 megabits per second. Just make sure there is a line of sight between the transmitter and receiver antennas to provide smooth video quality.

We use omnidirectional antennas for both transmitters and receivers, so even if the ship turns around or rotates 360 stupnjeva, it is best to install the antenna on the top of the ship so that the video signal will not be interrupted without obstruction.

Our network broadband transceivers are designed for use by drones or large fixed-wing aircraft. Their speeds can reach more than 800 kilometers per hour, so there is no problem for our transceivers to be used on ships.

You need to tell us what is the maximum distance between these two ships.
Knowing the distance between the two ships, you need to consider the waves between the ships, which may block the transmission between the antennas, so the antenna should be installed at the highest point of the ship as much as possible.

Q: Good morning are you able to provide a quote to supply a wireless video transmitter system, upravljamo jaružalom i želimo prenijeti video s obale na jaružalo na maksimalnoj udaljenosti od 5 kilometara. It is in a marine environment so it would need to be robust and also run on 12 volti bez internetske veze.

Before introducing a specific model, our engineer has some questions below.

• 1. Do you need a one-way or two-way transmission system? Jedan način, means just transferring the video from the shore to the dredge. Dvosmjerna, means sending and getting the video or data from one side to another side.
• 2. Is the camera on the shore or dredge? and the receiver is on the shore or the dredge. We need to consider the special case of the transmitter or receiver.
• 3. There are often undulating waves in the ocean. How high can the transmitting antenna and receiving antenna be installed?

Klijent: Apologies for the late reply, Please be aware that there is no internet connection available on the dredge.

• 1 – We would need a one-way with the camera transferring from shore to the dredge
• 2 – The camera would be on the shore at the end of the discharge pipe and the receiver and monitor would be on the dredge so can see what is happening on shore.
• 3 – We have attached a pdf with some pictures which show the ‘set up’. There is a mast located onshore as well.

u redu, jedan način, HDMI camera on the shore, the receiver on the dredge, transmission distance is 5km, odašiljač, and receiver will be installed a special case, (vodootporan, otporan na udarce, sprej protiv soli), s 3 pcs 1.8-meter length fiberglass antenna. (one for the transmitter, two for the receivers)

We recommended the below model, COFDM-908T-5W

Here is the test video for 10W at 20km.

We used the COFDM(DVB-T) tehnologija, which is similar to digital tv technology, with no need to use the internet. (The camera and transmitter are like a tv company transmitting tower, and the receiver is like a tv box at home)

For the maritime wireless communication environment, deploying MESH nodes on the shore base and ships can quickly establish a multi-hop broadband wireless network with high mobility, anti-smetnje, and beyond-line-of-sight transmission, providing voice, podaci, and video between the shore base and the ship. Multimedia integrated transmission service.

The wireless private network is connected to the customs command center, and the supervised ships are connected to the shore-based base station wirelessly.

Supports real-time dynamic networking of ship formations at sea, frequency hopping anti-jamming capabilities greatly enhance the electromagnetic countermeasures of formations at sea, and self-healing properties ensure that the wireless network has tenacious vitality, and any node failure in the network will not affect the entire formation The operation of the network can be an “unbeatable maritime mobile network”.

Quickly build a self-organizing network without a center, fast and flexible networking between boarding law enforcement officers and ships, multi-hop automatic networking, fast self-healing, adapt to various complex maritime environments, and support multi-channel high-definition video.
