9.2.2 Quality
Select the image quality here. Note that the quality (i.e. image size) affects the record rate
for a given number of days recording. Image quality may be adjusted to suit the particular
installation. Note that:
•
Higher quality images result in fewer images per second
•
Lower quality images result in more images per second
The actual size of the stored image in (Kbytes) depends on the content of the image.
Scenes with a lot of information result in larger images. Scenes with little information (e.g.
empty rooms), result in smaller images. The use of variable image size maximises the use
of the available hard drive capacity.
