Q:What are the security monitoring TV walls required?

A network video decoder is needed to board the TV wall. This device does not normally support VGA interface display devices.Ten thousand mast meets this kind of situation, thought that the plan which does not use the television wall is simple, a computer plus a projection may substitute, the cost is also low

Q:What's the difference between the hemisphere and the world of security surveillance cameras?

The hemisphere is small in size and can only be manually adjusted by 360 rotations. The camera has only two interfaces, power and video, which generally support DC, 12V, or AC 24V power supplies.

Q:Closed-circuit television monitoring system, video installation set what quotasfixed

Install the transmitter should apply the PDH quota, because the transmitter is E1 signals converge into optical signals equipment, first apply the machine frame, then apply the TSY2-001 quota, quota TSY2-002/TSY2-003 interface disk, finally use the test system channel test quota TSY2-046--TSY2-050.

Q:What do you need to add an ordinary home computer to a closed-circuit monitoring host?

First, make sure the processor is Intel Celeron AMD processor, if it is not, plus a video capture card (200 - 800 yuan) hard disk size, is the main document, this to you, the best memory 512, then the real running low,

Q:Closed-circuit monitoring software

This should be in the closed-circuit monitoring client software, which set up the boot from the start, if you have permission, you can reset your own, or directly press the WIN key into the task bar, use other programs

Q:Can the engineering monitor and test instrument measure the closed circuit and the network line?

Yes, you can test the website or video line

Q:The difference between IP monitoring system and analog system

The analog monitoring mode has been declining in recent years. The main defects are that the transmission channel is too expensive to install, the system structure is complex, the monitoring center equipment is various, and the operation is trivial. The system consists of cameras, video recorders, TV wall, surveillance control matrix, image processor, decoder and other auxiliary equipment, the coaxial cable for image transmission medium to the twisted pair as the control signal transmission medium, equipments, complex structure, expansion of the poor, and most of the equipment is a special equipment that requires the operator by training have the corresponding operation ability.

Q:Why is surveillance camera also called closed-circuit?

Yes, it can be understood, because it can only be used in a certain space, just like the VOD system in KTV, CCTV, someone's home is not received, the cable is not closed.

Q:Common faults in closed-circuit television monitoring and their solutions

Device fault caused by incorrect power supply. The incorrect power generally has the following several possibilities: power lines or power supply voltage is not correct, the power is not enough (or a road supply line size is not enough, the big buck), transmission line power supply system of the short circuit, open circuit, instantaneous overvoltage etc.. In particular, equipment failures due to power supply errors or transient overvoltage have occurred. Therefore, in the system debugging, before power supply, we must seriously and strictly check and check, should not be taken lightly.

Q:What is the working principle of TV wall display in security monitoring system?

TV wall display, general use monitors, monitors, television, as well as splicing screen, splicing screen is divided into DLP, PDP, LCD splicing.Analog surveillance generally adopts video matrix, through the BNC interface on the wallDigital monitoring usually adopts digital matrix through the upper wall of VGA interfaceIf splicing screen is adopted, arbitrary splicing can be realized by splicing processor.
