Q:Monitor the camera, how much money one, the kind of video

20x4 = 80, camera power (outdoor): 25x4 = 100, auxiliary material (connector what little things): 50 wire you have to see your actual situation, and more use Flowers, less with less flowers

Q:Monitor camera parameters how to see the bigger the bigger the better?

Suitable for the best is the Yeah, professional monitoring, space information

Q:What is the difference between monitoring the camera and the usual?

3. Camera effect: monitoring with the camera, generally require high clarity, because the current computer camera commonly used sensor chip is Micron or modern photographic chip, these two kinds of chip camera, clarity are similar, if the use of 5 glass Lens, then the requirements are less stringent occasions are generally able to meet the basic requirements, and 30 frames per second speed is basically able to meet the monitoring needs. If you need better clarity, you can use the physical dynamic 1.3 million camera (not online nonsense 1.3 million, need to emphasize that the sensor chip and interface chip support physical dynamic 1.3 million camera, can really be considered 1.3 million ), This camera is generally better imaging results than the use of magnesium light and modern sensor chip camera, can get better than the average physical 350,000 camera effect, but the bandwidth occupied and CPU occupancy rate is very high. So easy to monitor the camera system easy to use.

Q:Monitor the video recorder has been unable to work what is the reason

VCR power supply problems. You can change the power adapter to try;

Q:There are cameras at the fork in the expressway

Highway cameras are generally high on both sides of the road, it is easy to see. Fixed speed device with radar speed function, video surveillance equipment with automatic capture reversing, parking, retrograde, parking up and down and other functions, high-definition bayonet equipment with radar speed, capture carts, not seat belts, 2:00 to 5 Point bus pass pictures and other functions. Highway monitoring system common three kinds of products:

Q:The working principle of the camera with infrared light

Second, the infrared camera imaging principle In the night vision monitoring system, the conventional approach is to use the visible light, but this way there can not be hidden, easy to monitor the target and other shortcomings, so use less; the current hidden, scientific night vision monitoring Is the use of infrared camera technology. Infrared camera technology is divided into passive and active. Passive infrared camera technology is the use of any substance in the absolute zero (-273 ℃) are more than infrared radiation, the higher the temperature of the object, the more infrared radiation. The most typical of the cameras made with this principle is the infrared camera, but this special infrared camera is expensive and therefore limited to military or special occasions. The active infrared camera technology is the use of infrared light radiation "lighting" (mainly infrared light), the application of ordinary low-light black and white camera, color to black and white camera or infrared low-light color camera, feel around the scene and the environment reflected back to the infrared light to achieve Night vision monitoring. Active infrared camera technology is mature, stable, become the mainstream of night vision monitoring.

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

Again, in the dark environment test: some of the camera's infrared light is hidden, this situation will be in power, and then placed in a dark environment to test to know. (Can see the output screen is illuminated screen that has infrared function)

Q:Hello, because no electric video recorder did not manually set, but I would like to look back a few days before the monitor can be transferred out

2, although the surveillance camera access to the hard disk video recorder, but the video storage of the hard disk failure, can not playback.

Q:Camera gun 4MM, 6MM refers to what?

Camera gun parameters in the 4MM, 6MM, etc. refers to the camera is configured lens focal length.

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

If you want to video directly to the hard disk recorders, take a video line, the two do a BNC head (the electronics market to sell more), one end of the camera, one end of the hard disk recorders, hard disk recorders then TV or LCD Is a small set of video surveillance system.
