Professional is this: from the camera's lowest vertical angle and 45 degrees direction of the corner shot to the ground for the vertex to draw a square to the corner, for most of the camera is within the square of the collection area is invalid, basically applicable to The market of 90 percent of the camera, very few high-value professional equipment, except, even if the square of the two sides can sweep the image of the place has been seriously deformed, there is no legal effect, this has been in court there are numerous cases

Q:Monitor the difference between the camera 720p and 1200 lines

1200 lines, if simply literally on the analog camera system that represents the clarity of the 1200 TV line, but the current market, the emergence of the 1200 line, strictly speaking, is a mountain plug products, is a digital camera using 1080 X 1960 CMOS lens to convert products into analog cameras.

Q:Wireless remote monitoring camera farthest to monitor how far

As long as there is a mobile Internet, where you can see, there is no distance limit. The

Q:Remote monitoring principle

First, the video signal from each camera is input to the RV-2000 video capture terminal. Then, the RV-2000 video capture terminal converts the video signal into a digital image of 25 frames per second through the MPEG-4 image compression algorithm, After the audio and video data stream through the optical fiber network forwarded to the video monitoring center; Finally, the video monitoring center of the computer to receive the front of the image and sound data from the decompression and through the computer display screen and sound card for real-time monitoring.

Q:What is the number of lines that a surveillance camera needs to use?

General monitoring of the camera needs a line of power lines, video lines, audio lines and so on

Q:What is the power consumption of the camera day?

According to the DC power conversion efficiency of 80%, the input power = 18W / 0.8 = 22.5W

Q:What is the camera's shooting range? How much is the diameter?

The lens used in the camera is similar to the SLR camera, and is arranged in the order of 2.8mm, 3.6mm, 4mm, 6mm, 8mm, 12mm, 16mm, 24mm and so on. The smaller the number of millimeters, the wider the picture taken by the lens, but the closer the distance is; the larger the number of millimeters, the narrower the screen taken by the surveillance camera, but the farther the distance is.

Q:Monitor the camera gray screen

1, power reasons. The basic can rule out this reason, because it has been running for 2 months. If you do not worry about the power, you can do this: remove the camera, change the new power (or now use a normal) next to the host test. (Because the output line of the power cord is too long, there may be insufficient voltage.)

Q:Monitor the camera has a video port, what is this mouth, then what machine, direct access to the TV can you?

You saw the bayonet bulb it, you go to the computer city to buy a plug on it, the output of the video signal, before the old TV also have this video interface.
