Q:3.6mm and 6mm surveillance camera can see the screen angle is how much

This depends on how much the face of the CCD friends, 1/3 is 71 degrees 1/4 is more than 51 degrees

Q:Home pinhole wireless surveillance camera where to sell? How much is the miniature camera?

For example, backgammon, process-oriented design ideas is the first step to analyze the problem: 1, start the game, 2, sunspots first, 3, draw the screen, 4, judge win or lose, 5, turn white, 6, draw the screen, 8, return to step 2, 9, output the final result. The above steps with each of the different functions to achieve, the problem is solved.

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: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:An accurate calculation formula for monitoring the focal length and actual distance of the lens

While the use of long focal length lens can see the car's license number (the car occupies most of the area on the screen), but can not monitor the entire car park

Q:Wireless micro-surveillance camera how to see what to shoot

If it is with memory, then the memory card can be placed on the card reader to the computer to play, if there is no memory, then there is a receiver, the receiver connected to the hard drive will receive the signal stored in the hard drive, Can be played through the hard drive on the monitor.

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:How to clean the surveillance camera

Finally, wipe the lens with deerskin clean.

Q:Hai Kangwei as the camera mapping problem

And then find the monitoring section, their own configuration of a fixed IP address, or ip address is erratic but a headache, I red line part

Q:Dahua monitor a single image upside down, the rest of the camera are good, how the matter, had been good!
