image and drag a rectangle area  in  the lower right direction, then the mini PTZ camera system 
will move the position to the center and allow the rectangle area to zoom in. Use the left key of 
mouse to drag a rectangle area in the upper left direction to move the position to the center and 
allow the rectangle area to zoom out. 
  Proportional Pan/Tilt 
Proportional pan/tilt automatically reduces or increases the pan and tilt speeds according to the 
amount of zoom. At telephoto zoom settings, the pan and tilt speeds will be slower than at wide 
zoom settings. This keeps the image from moving too fast on the live view image when there is a 
large amount of zoom. 
  Auto Focus 
The auto focus enables the camera to focus automatically to maintain clear video images. 
  Day/Night Auto Switch 
The mini PTZ cameras deliver color images during the day. And as light  diminishes at night, the 
mini PTZ cameras switch to night mode and deliver black and white images with high quality. 
  Slow Shutter 
In  slow  shutter  mode,  the  shutter  speed  will  automatically  slow  down  in  low  illumination 
conditions  to  maintain clear video  images by  extending  the exposure  time. The  feature  can be 
enabled or disabled. 
  Backlight Compensation (BLC) 
If you focus on an object against strong backlight, the object will be too dark to be seen clearly. 
The  BLC  (Backlight  Compensation)  function  can  compensate  light  to  the  object  in  the  front  to 
make it clear, but this causes the over-exposure of the background where the light is strong. 
  Wide Dynamic Range (WDR) 
The wide dynamic range (WDR) function helps the camera provide clear images even under back 
light circumstances. When there are both very bright and very dark areas simultaneously in the 
field  of  view,  WDR  balances the  brightness  level of  the  whole  image  and provide  clear  images 
with details. 
  This feature varies depending on mini PTZ camera models. 
  White Balance (WB) 
White  balance  can  remove  the  unrealistic  color  casts.  White  balance  is  the  white  rendition 
function  of  the  camera  to  adjust  the  color  temperature  according  to  the  environment 
automatically. 
  Patrol 
A patrol is a memorized series of pre-defined preset function. The scanning speed between two 
presets and the dwell time at the preset are programmable. 
  Pattern 
A pattern is a memorized series of pan, tilt, zoom, and preset functions. By default the focus and 
iris are in auto status during the pattern is being memorized. 
  Pattern function varies depending on mini PTZ camera models. 
  Power Off Memory 
The mini PTZ camera supports the power off memory capability with the predefined resume time. 
It allows the mini PTZ camera to resume its previous position after power is restored.
