Q:What kind of surveillance camera is good for the hotel?
Corridor: generally with ceiling-mounted explosion-proof hemisphere, easy to install, the overall effect of beautiful.
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.
Q:Housing surveillance camera
According to the length of the cable, the camera's clarity is good or bad, a good camera generally a 160 or so can, the two together also 500 almost.
Q:Monitor the top ten cameras
Foreign brands: SONY, Panasonic, Samsung, Sanyo, Pyle high, Honeywell, and so on domestic brands: Yaan, Ming King, SOWZE, Hai Kang Wei as. The The Too much
Q:Monitor the camera's focal length 4 meters good or 8 meters good
The focal length is: mm. The smaller the data, the larger the shooting angle is, and the larger the captured range
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: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:Monitoring camera 6mm 8mm 12mm 16mm length and width can be according to how much.
At the same time, the same focal length, length and width shooting range also with the camera CCD has a relationship. Charge - coupled Device, Charge - coupled Device. It is a semiconductor device that converts optical images into electrical signals. At present, most of the CCD chip used in the surveillance camera is 1/3 "and 1/4", that is, the target size is 1/3 inch and 1/4 inch. CCD target surface size, CCD and lens with the situation will directly affect the size of the field of view and image clarity.
Q:Hai Kangwei depending on the surveillance camera how to achieve continuous automatic capture, such as a second catch a?
If you want to install ten cameras then the traditional camera is necessary for each coaxial line must be inserted at the same time a video recorder can be used normally, but the network camera can add a switch, that has ten network switches into only need Through a network cable to pull another switch on the normal use, so do not have to spend a lot of trouble, save a lot of labor)
Q:Home surveillance camera with which brand is good?
In addition to their own home, back to my parents to buy one, my parents live home, a year when the New Year to go back to see them, with their time less, with this monitor, I can see them every day old, you can Like the same as the micro-confrontation. not bad.
