This feature provides the ability to ensure that cameras are always showing the desired view, thereby flagging deliberate or inadvertent camera tampering or position shifts. Any movement of the camera or change in the camera view against a reference view will be indicated in this feature with the percentage change of the current camera view vs the reference image shown. Our sophisticated Adaptive Pattern Matching algorithm ensure that even in variable environmental conditions the reference image comparisons are accurate. This means that if you setup a camera reference image in the daytime, the algorithm will “adapt” when comparing the view against a night-time image. We also provide the ability to export the reference images for later retrieval.
