2. Please note the storage space
calculated by this form can be considered ONLY as a ballpark figure. Your
surveillance environment may effect the storage space you need and there is no
way this form can take into account all possible variables. This form makes
general assumptions based upon your input and calculates drive space
3. Calculation is based on MPEG4 video compression. If you use older
schema then INCREASE the size of the HDD it suggests. When using H264 and
newer compression techniques, the size indicated will be larger (perhaps
much larger) than the size that is actually required.
This page is provided as a convenient tool for selecting
lenses. Due to the large number of unpredictable factors in every surveillance
environment, the calculation can not be assumed to be exact. Use caution when
selecting a lens. We suggest that you always purchase a lens with a greater
field of view than this calculation indicates.
