A Vari-focal is a lens that is designed to meet the most challenging jobs by giving the installer the flexibility to adjust between different focal lengths using only one lens. When the situation calls for an odd focal length lens or you are not sure of the correct focal length required for the installation, using a Vari-focal lens is the perfect choice. How many times have you or your installer set-up a job just to be called back because the customer was not satisfied with the field of view of the picture? More than once, most likely. A simple adjustment to the zoom and focus on a Vari-focal lens is all that is needed to rectify the situation on the spot: a less costly and time-consuming prospect than having to order and install a different monofocal lens altogether.Surveillance effects are maximized since any desired angle of view can be obtained.

How to choose Infrared LED

infrared LED,Camera, lens,cover and battery consists a total package monitor system. In the monitor system design we should pay attention to below detalis while choose a imfare lamp.

CCD image sensor with a wide range of photographic spectra, the photographic spectra not only include the visible spectra but also range to infrared area, as so CCD image sensor have high-quality image by infrared light in night unvisible light. Traditional color camera transfer the color image as this way: CCD image sensor can split green,blue,red three signal, and combine these three signal into color image in the visible area.

By technology advanced, there are color daylight or black-white nightlight camera, they achieve the function by using two CCD image sensor switch, but the disadvantage is low image-quality?An infrared low-light color camera has 4 multiples infrared sensitivity and later it will be the popularity by the cost lower down.

The most low-light camera photo scene when the brightness is low to a certain degree of Er Shi camera video output signal level to a specified low value of the scene brightness value. Determination of this parameter should be specified the size of the lens aperture F. For example, using the F1.2 lens.

When the scene illumination photography 0.02Lx low value, the camera outputs a standard video signal amplitude 700mv amplitude of 50% -33%, claimed that the best illumination for this camera is 0.02Lx/F1.2. Some camera manufacturers are given the most different when the illumination aperture F. When choosing the best camera infrared light illumination above requirements.

The effective range of infrared light will be affected to some extent. Should remind the user that the camera technology on the market performance marked the most illumination, there are two anomalies, one is the subject of most camera manufacturers is the so-called target surface illumination illumination, CCD image sensor on which the light intensity, illumination than the scene about 10 times lower; the other is individual camera manufacturers or vendors false minimum illumination. Comparison of the market economy, black and white camera (priced at 700 yuan, some of the most illumination marked as 0.01 ~ 0.02Lx)

If, using the infrared lamp illumination is the most requested video camera 0.02Lx, will inevitably affect the effective radiation from the infrared light, while most low-light 0.02Lux camera purchase, prices may be less than 0.1 ~ 0.2Lx camera is about twice as high. Then there are two options, spend more money on the camera, the infrared light on the little money; less to spend on the camera, the infrared light to spend more money on. Experience has shown that distance outdoors, especially when the former is a more economical choice.

Camera has automatic shutter and AGC automatic controller functions. Camera lens has automatic aperture to fit for the night-dawn light illuminance
