3xLOGIC VIGIL Server - Manual (Page 74)

9.1.1 General
To reduce CPU usage, Vigil Server reduces the resolution of the image used for Analytics calculations. It is strongly recommended
that the Max Kernel Resolution be set to CIF. Increasing the Max Kernel Resolution setting will only affect camera views with
extremely wide camera angles where objects are small enough that they are lost when the resolution is reduced to 352 x 240.
Max Kernel Resolution
CIF 352 x 240 (recommended)
4CIF 704 x 480
Megapixel 1280 x 1024
Full Resolution Full resolution recorded from the camera
Warning: Increasing the Max Kernel Resolution will result in increased CPU usage. Please monitor the CPU usage closely.
