Auto-Tracking Dome Camera

Have you tried an auto-tracking dome camera?  Be careful if you do because once you get hooked on them, it is pretty difficult to keep you from getting more.  These cameras represent some of the highest quality electronics available today.

What is an “Auto-tracking Dome Camera?”  It’s a special type of PTZ (Pan-Tilt-Zoom) camera that can lock onto moving objects and follow them where ever they go (within line of sight to the camera).

To use such a camera you first need to install it, and then set it up, and finally let it work so you don’t have too!  Auto-tracking Dome Cameras have circuitry built right in that allows them to recognize a moving object, get a lock on the target , and follow it until it leaves the area of the Field of View for the camera.

This is particularly useful if you require constant live monitoring of your security system.  For example, if you were using this camera in a parking lot, not only could you set it to watch cars come and go, but it could even track the people getting out of the cars.

Security Camera King offers two different auto tracking dome cameras, both made by Veilux.  Product# VP-ATDNC27X has an optical zoom of 27X and an additional digital zoom of 10X.  This means the total zoom effect attainable with these cameras would be up to 270X.  In addition here are some of the features of this camera:

  • 520 TVL high resolution output;
  • Minimum illumination is 1.0 Lux for day mode and .5 for night mode;
  • Automatic stabilization of images by reduced flicker;
  • Motion tracking, Intelligent Surveillance with an alarm function;
  • Preset, auto cruise and specified pattern scan function;
  • 360 degree continuous pan;
  • 0 to 9 degree tilt from horizontal plane as well as auto flip 180 degrees;
  • Iris, focus, and white balance;
  • Backlight compensation;
  • Wide Dynamic Range (WDR); and,
  • Outdoor version is IP66 rated for use out doors;

The second camera is very similar to the latter, with some slight advantageous changes.  Product# SVP-ATDN36X has an optical zoom of 36X and an additional digital zoom of 10X.  This means the total zoom effect attainable for this model would be 360X.  This camera is vary similar to the previously mentioned model so the features list will only include those features or items that are different:

  • 540 TVL high resolution output;
  • Minimum illumination is 0.1 Lux for day mode and 0.01 Lux for night; and,
  • Heater and blower included in outdoor model.

It’s only fair to note that PTZ cameras that can be controlled remotely, when coupled with special software on the DVR, can also track or follow objects.  However, in this case instead of the technology lying with the camera, it is actually the DVR that contains the software and does the work.  It uses software to analyze the video sent to it, and then initiates the commands to the camera to PTZ so as to stay with the object tracking it.

So as you can see today’s digital video camera systems can handle some pretty complex tasks without the need for any human interruption.  What’s more is that on PTZ camera mounted in the proper place may often be able to take the place of 3 or even 4 stationary cameras.  Even though the PTZ camera may be in the moderate price range this fact alone helps to reduce costs, if not directly than at least indirectly.

Another added value feature of Security Camera King’s DVRs is that all but the Elite Mini Economy can control PTZ cameras with just a mouse.  Point to where you want to go, and the PTZ camera aims there.  However, if you prefer more conventional means of control, Security Camera King does sell a separate PTZ control that has a joystick and a keyboard designed specifically for use with PTZ cameras.
