 540 lines of horizontal resolution. 
 50dB signal to noise ratio. 
 Built-in 3.6 times zoom lens (2.8 ~ 10mm) 
 Automatic dark Regional Compensation (ABS) 
 Auto Back Focus adjustment (ABF) 
 Automatic dark Regional Compensation (ABS) 
 Dark Regional Compensation (ABS) automatically the first to adopt the new digital signal processing technology to automatically detect dark areas in images, access the data of the brightness of dark areas around, and color adjustments in real time through the best correction curve calculated for each region . The image processing algorithms in real-time adjustment and correct backlight and dark areas, reproduce natural, clear images. 

 Auto Back Focus adjustment (ABF) 
 Mechanical treatment plant 
 Conversion from color mode to black and white mode, with automatic focus adjustment (ABF) device camera automatically for precise focusing on the CCD position to accurately coke. This solves the problem of traditional cameras remove the IR filter, the image becomes fuzzy. 

 Automatically provide accurate focusing 
 Auto Back Focus adjustment has automatic focus adjustment function can touch a single button. When the conversion from color mode to black and white mode, the position of the CCD automatically adjusts to ensure accurate focus throughout the day. 
 Focus adjustment function automatically after 24 hours to ensure that you can obtain the accurate recognition must be a clear picture of all-weather; improve monitoring efficiency to reduce operating costs. 
 Camera or change the wiring is installed, the ABF function to reduce the time to manually adjust the focus, thereby reducing the cost of installation and maintenance.
