Q:Monitor the camera mentioned in the three stream, what is the meaning of ah, which three?

The three stream uses a high bit rate bit stream for local high definition storage, such as h.264 D1 encoding, all the way low bit rate stream for network transmission, such as D1 / CIF encoding, another way ultra low bit stream for 3G Network transmission, mobile phone viewing, such as QCIF, while taking into account the local storage and remote network transmission.

Q:I want to install a set of monitoring, a total of 15 cameras, the farthest camera from the hard disk recorder 500 meters, how to install? What equipment?

Need to install the video capture card and monitor the number of camera cameras to determine the number of acquisition cards (a collection card with four cameras), if the future will increase the camera, you can directly use 8-way card card collection of about 300 yuan, about 200 camera To a few thousand range

Q:How to monitor the camera with the venue, what type of camera installed in what kind of site, the camera installed how much the number of lenses should be equipped with light board.

Monitoring camera should pay attention to the following: camera clarity, illumination, image storage time, etc., it is recommended to monitor the equipment franchise stores (generally every city computer city) asked clear.

Q:Monitor the camera automatically zoom, electric zoom, manual zoom, zoom lens meaning and difference?

In the surveillance camera, there is generally no automatic zoom, but there is auto focus, such functions generally appear in the integrated camera, the decoder sends a zoom signal to the camera, the camera to zoom work, zoom work is completed, then the image Is blurred, you need to focus, a lot of integrated camera with auto focus function, to complete this focus work. There are some high-end camera (mainly high-speed ball) with a trajectory function, which is set in advance camera rotation and zoom information, after this camera has been set in accordance with the set of good track non-stop tour, which can see Do automatic zoom.

Q:Monitor the camera if the power supply to him a large current, pay attention to the current is not the voltage, the voltage is 12V, then what will happen to the camera?

The voltage is constant, the current is not increased, such as the camera comes standard with the adapter power supply is 12V / 1A, if the switch for 12V / 5A or 10A, 20A power supply is the same, will not have any impact on the camera. The actual operating current of the camera does not increase as the power of the power increases.

Q:P2p wireless monitoring camera how to achieve remote monitoring

I have a camera can be directly through the customer service side to add the camera id can be achieved remote monitoring, do not do port mapping

Q:Commercial surveillance camera and usually use the camera is connected together? How can we find matching software?

Under normal circumstances, the ideal monitoring camera delay in 200ms or so, slightly worse IPC delay in more than 400ms. If the delay of the network camera to reach more than 400ms, you need to consider the serious delay phenomenon for the front-end equipment alarm.

Q:What is the meaning of the high definition and standard definition of the surveillance camera?

Sub-level is not the same, there are industrial-grade, home-class, high-definition standard than the standard standard strict.

Q:HD camera and infrared camera difference

Q:Use home computer camera how to install home monitoring?

The first transmission distance monitoring camera installation, generally need to use a few meters to tens of meters ranging from the transmission distance, but in accordance with the provisions of the USB standard, USB device, the longest transmission distance is 5 meters, so USB are Can not use long distance, which is what we use the USB camera to do monitoring the first problem encountered, the camera transmission distance. In fact, USB transmission distance can be resolved, USB can be extended through USB? HUB transmission distance, each additional HUB, you can extend the 5 meters, a total increase of 5 HUB, which is extended 5 times, each 5 meters, so The longest extension of 25 meters. Why is the USB demanding on the distance so strict? This is because the USB signal frequency is very high, the line in the process of transmitting the signal attenuation of the signal is very large, when the signal attenuation can not maintain the normal transmission of the signal, WINDOWS will prompt "to find unrecognized USB device" So the general distance can not be more than 5 meters!
