Q:What is the difference between a camera and a monitor?

Camera digital camera The wide range of cameras, the basic principles of its work are the same: the optical image signal into electrical signals, in order to facilitate storage or transmission. When we shoot an object, the light reflected on the object is collected by the camera lens, focusing it on the light receiving surface of the camera (such as the target surface of the camera tube), and then through the imaging device to light into electricity, that is, "Video signal". Photoelectric signal is very weak, need to be pre-amplifier circuit to enlarge, and then through a variety of circuits for processing and adjustment, the final standard signal can be sent to the recorder and other recording media recorded, or spread through the transmission system or sent to the monitor display.

Q:What are the problems with the surveillance camera?

Wait for you to meet the situation to say it again, I give you answer, you ask the question is like to buy a mobile phone, mobile phone will generally what the same problem. People are so depressed! The The Surveillance cameras, Dongguan Le Pu Electronic Technology Co., Ltd., this is very good!

Q:Monitor the camera what is the zoom

Zoom, is the focal length, that is, long-term problem! Is to see the camera to the object far, closer. Change is to see the object to enlarge. Do you understand that?

Q:Home monitoring system which brand is better

Home surveillance camera need to be easier to install and fixed, camera accessories to complete, do not need to buy some additional accessories to help fix.

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:Dvr monitor the video recorder without image output is what the problem

If the format is only the system disk, then the system, monitoring software must be reloaded, set; VCR is the embedded host, format only to clear the video data, the system program and settings are stored in the motherboard chip So there is no need to reset it.

Q:Monitor the camera 1 road 4 what is the difference

Camera regardless of a few road, only the video recorder was divided, four representatives can take four cameras!

Q:How to install a surveillance camera

1. Remove the camera, and then plug the USB port into the computer interface, if long-term use, it is recommended to insert the board.

Q:Monitoring the camera has a 700 line with 1080 lines of 900 lines is what does that mean? consult

700 lines refers to the horizontal direction of the camera's resolution is 700 lines. The number of digits indicates that the higher the resolution, the more details you can shoot.

Q:An electronic surveillance camera every month to consume how much electricity

Electronic monitoring camera power consumption is very low, with infrared general 6W, that is 24 hours work, the monthly power consumption 6 * 24 * 30 * 0.001 = 4.32 degrees. Without a little lower than the infrared, with a red ball machine power consumption of about 30 degrees per month.
