Geovision GV-VD320D

Hello I have a used Geovision camera. When removed it worked. Untested since.
The Geovision GV-VD320D is a vandal-proof dome megapixel IP camera is capable of capturing a video image of 2048 x 1536 (3 megapixel) resolution at 20 frames per second. This megapixel camera has a 1/2.5" progressive scan CMOS image sensor.
The GV-VD320D vandal dome is vandal proof and weatherproof (IP66 compliant). This megapixel dome camera is capable of seeing in zero light using the built in IR LEDs (infrared). In addition, the 2.7 ~ 9 mm varifocal lens allows the installer to adjust the video field of the image to the exact angle for your surveillance application.
This megapixel dome camera can provide dual video streams which are selectable from H.264, MPEG4, and MJPEG video types. The tri-axis mounting mechanism for this camera enables the installer to do a ceiling or wall mount (Mounting Positions).
