Q:What is the power of the camera used for monitoring?

If all of the moving point, then the power supply per set of AC24V / 2A, each 50W, 31 * 50 = 1550W, that RVV2 * 0.75 power cord is not enough.

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

So when you need to monitor the panorama to see the local, the general should consider the use of electric two variable or electric three variable lens. Of course, in the selected lens under the premise of the use of high-resolution cameras and monitors can be monitored objects in the smaller size can also see the local details.

Q:Monitor inside the infrared network camera infrared light automatically switch and synchronous switch What does this mean?

Automatic switch, that is, the camera detects the outside environment, light black to a certain degree of image to turn black and white. Morning to a certain extent turn color.

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:How to use the network cable to connect the surveillance camera?

Short distance directly with the network cable can be, I remember as if 40 ~ 70 should be no problem (my longest used 20 to 30 meters). If you can buy twisted pair transmitter, then each pair of cameras need a pair of distance greater than 300 meters with active, active recommended front-end ground. If you use a network camera or a normal camera + digital module (this name is not allowed) direct crystal head + switch.

Q:What kind of surveillance camera is good

The performance of the camera is mainly the minimum illumination (that is, the ability to adapt to the dark light), focal length (according to your workshop to install the camera position and to monitor the range of fixed focus, the shorter the shorter the focal length of the larger image is not very clear

Q:Monitor host can not find the camera ip how to do?

Please make sure that the equipment is working properly (power supply is normal).

Q:A camera for an hour how much space

This depends on the camera to shoot the quality of the picture, give you a camera 130W, each picture is 30K look, the picture is 10 Zhen, then every 10 is the screen, that is 300K, 1 hour 3600 seconds , Take out 1080000KB to remove 1024, that is, 1G look like

Q:Monitoring camera Sony chip how to identify

Samsung low solution: with SONY SS-11 (SONY CCD out of stock when the most commonly used to mix)

Q:The working principle of the camera with infrared light

Infrared emission diode (IR LED) infrared lamp principle is: by the infrared light-emitting diode matrix composed of light. Infrared emission diode from the infrared radiation efficiency of high materials (commonly used gallium arsenide GaAs) made PN junction, plus forward bias voltage to the PN junction injection current excitation infrared light. Spectral power distribution for the central wavelength of 830 ~ 950nm, half-peak bandwidth of about 40nm or so, it is narrowband distribution, for ordinary CCD black and white camera can feel the range. The emission power of the infrared light emitting diode is expressed by the irradiance μW / m2. The maximum radiation intensity of the infrared diode is generally in front of the optical axis and decreases with the increase of the angle between the radiation direction and the optical axis. The radiation intensity is 50% of the maximum value of the angle is called the half intensity radiation angle, that is, half power angle. The radiation angle of the infrared light emitting diodes of different packaging process models is different.
