Q:6mm camera and 3mm camera What is the difference
3, the smaller the smaller the effective monitoring of the distance, the more the larger the effective monitoring of the farther away from the lens.
Q:What's the number of lines that a surveillance camera needs to use?
2, video cable (transmission video signal, syv75-3, syv75-5, syv-75-7 these three are the most commonly used)
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:What is the effective range of infrared surveillance cameras?
Infrared probe about 3 meters to 12 meters between ~ ~ some special except to see the main object of the strong degree of reflex is not strong.

Q:Monitor camera parameters how to see
Aperture: the aperture installed in the back of the lens, the greater the aperture open, the greater the amount of light through the lens, the higher the clarity of the image; the smaller the aperture, the smaller the amount of light through the lens, the image clarity low. Usually with F (luminous flux) to represent. F = focal length (f) / light aperture. In the camera's technical indicators, we can often see 6mm / F1.4 such parameters, which indicates that the focal length of the lens is 6mm, luminous flux of 1.4, then we can easily calculate the aperture of 4.29mm. In the case of the same focal length f, F value is smaller, the greater the aperture, reach the CCD chip, the greater the luminous flux, the better the lens.
Q:Monitor the camera in the monitor screen appears in the camera 001 what meaning
One is the name of the video recorder, you can delete the number from the VCR menu, channel settings.
