Multiplexer which brand is good multiplexer networks offer multiplexer SUV

4 channel video multiplexer
4 channel video multiplexer mainly in video monitor system to increase monitoring point, the transformation of old projects and new projects is not easy to construction and development of new
Products. Application of frequency reuse and signal superposition technique, 1 or more video signals to the other 1 channels of video signals, through the same root
Coaxial cable transmission. Monitoring can be achieved by coaxial cable original video camera flash. Save the construction of wire and reduce
The difficulty of construction, is the preferred product retrofit old engineering.
A, product introduction:
Shenzhen yuanfan brand YF-SF804 4 channel video multiplexer is to control the video signal and the RS485 inverse controller 4 cameras to end
Signal binding common transmission in a coaxial cable. It is using frequency division multiplexing technology, namely the control signal and video signal modulation in not
At the same frequency, and then combined together to transmit, it can be implemented in a wire simultaneously with the same direction or reverse transmission of the four video signal and
The RS485 control signal, using ordinary video lines can transmit 600 meters, which can effectively lift cable utilization, has clear image, installation.
It features.
4 channel video multiplexer which solves the remote control signal transmission, transmission distance can be greatly extended video signal. This transmission
Characteristics, save materials and cost, convenient construction, free debugging, stable, reliable, and other, more flexibility in the system expansion and renovation,
Is the ideal equipment of video control signal transmission.
Two, product features:
The equipment adopts 1, new projects, can be put to the three video cable into a video cable, save cable usage;
2, renovation project, the new increase point can be the nearest access;
4, special use, video signal and data signal transmission can be bound together in a line, and does not need additionally distributed data line (Note: Data
The signal is composed of data plate plug-in type, are respectively arranged at the transmitter and the receiver, the user can choose according to need to plug, so
Easy to use, save the RS485 transmission wire);
Transmission 4, suitable for all kinds of belt PTZ control or without PTZ control of video signal and the data signal control;
5, in the video cable can also be in the RF cable COSCO distance;
6, built in ESD protection circuit (using the breakthrough semiconductor element) signal isolation module, the effective protection of the main control room equipment without external static
Electrical interference;
Install 7, modular design;
8, three video coaxial bidirectional transmission;
9, the transmission distance (SYV75-5 coaxial cable can transmit 600 meters, two other road can transmit 1200 meters) while guaranteeing the image of
The 4 stage effect;
10, 4 channel video multiplexer free debugging, adaptive: as long as the range of transmission distance, the device will automatically adjust their index, make the electric
Road can be compatible with 0 distance and the distance adaptive, so as to achieve the best effect, strong anti-interference ability, stable and reliable work;
11, by using the frequency multiplexing technology can effectively resist all kinds of interference;
12, the real time image transmission, no frame loss without delay, broadcast image indicates;
14, simple wiring structure, convenient, low cost, convenient construction, shorter working hours;
14, products using the patch installation process, safeguard the stability;
Three, the debugging method:
4 channel video multiplexer connection is good, without debugging, using the new adaptive technology
The transmitter to the receiver using SYV75-5 coaxial far transmission 600 meters
V1 is through the VIDEO signal, V2, V4 modulation signal, the anti-interference ability
Four, 4 channel video multiplexer instance:
Example (1): the project has been completed, demand increased do one or more cameras?
Answer: this kind of problem is very common, often in the project after Party A will propose to increase the monitoring point requirements, usually way is only
Tube cable trench wear again, very labour and material consuming, we recommend the use of a set of 2 channel video multiplexer, using a video next
The 2 line transmission at the same time (or 5) video to solve.
