Q:Outdoor surveillance camera that kind of good, how the price

In the TV monitoring system engineering design, often involves the TV monitoring system equipment selection, especially the front-end camera part and the terminal display part of the match is very important. Therefore, we use the TV monitoring system equipment, can not be any match, according to the monitoring of the environment of the environment and the conditions of illumination and the requirements of the target to be monitored, follow a certain principle to choose.

Q:20 meters away with the number of mm monitor camera lens appropriate?

1/4 "CCD lens in the line of sight with 1/3" CCD no difference, but the angle will be more narrow, while the shooting of the object will appear taller.

Q:What is the difference between monitoring cameras CCD1 / 3 and 1/4?

Only 1/3 inch, 2/3 of the lens through the aperture of 2/3 inch, so under the same lighting conditions, 2/3 lens allows more light through, thus indirectly enhance the camera's illumination, ? 16MM of the small perspective, according to far, 8MM lens perspective, according to the relative, relatively speaking, the principle of record: the greater the number, according to the more distant, the smaller the angle; the smaller the number, The more widely

Q:What color is the monitor when the camera is turned on?

Most of them are red, there are white light and no red light at night no light, and the specific relationship between the wavelength of infrared light.

Q:What is the abbreviation for monitoring the OLUX on the camera?

The ambient illumination can be divided into several ranges: ultra low illumination (10-2lx), low illumination (10-1lx ~ 10lx), general illumination (10lx ~ 105lx), high illumination (106lx or more). See Table A.1. Table A.1 Environmental Illumination Range Environmental Illumination lx 2 × 10-5 to 2 × 10-4 7 × 10-4 to 3 × 10-3 3 × 10-2 to 3 × 10-1 5 5 × 102 3 × 103 ~ 105 3 × 104 ~ 105 106 Examples of environmental conditions dark night stars moonlight dawn sunrise / sunset cloudy sunny flame

Q:Home wireless surveillance camera price, how much money?

HD network monitoring system is a popular in 2004, a high-definition home monitoring system, the main device is the wireless network camera. If you choose Puqing 30 million pixel price about 180 dollars or so, if it is 720P million HD price about 380 or so, with a 32G memory card price is about 140, computer display 500 yuan, so down the total About 820 yuan to 1,000 yuan or so. Of course, the above does not include the relevant accessories and storage control network DVR.

Q:The camera used to monitor the color of the screen is not normal. Blue as red. Red out is blue. New to buy the camera

First of all, you have to make sure your camera is no problem. Secondly, I would like to ask. Your camera is a centralized power supply, or a single power supply, power supply line transformer is not too far away from the camera

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?

If the voltage is 12V has been determined. The current is determined. The current is determined by the DC impedance of the camera. If the voltage changes, the current will change. If the camera is shorted. That its voltage also changed!

Q:Monitor the camera from the appearance of how to distinguish is not infrared

Many users in the purchase of infrared surveillance cameras will encounter how to distinguish between the infrared function of this problem. Here, we provide a way for everyone, hoping to help you solve this problem.

Q:Monitor the camera screen black
