3VR SmartRecorder Installation and Configuration Guide
Conclusion
Importance of Image Quality
This guide should have helped you to understand and optimize image quality so that you can now:
Better qualify what opportunities are strong fits for 3VR •
Set the appropriate level of expectations with partners and users •
Design a system that accommodates real world conditions •
Deliver a solution that is optimally effective •
Deeper understanding of the significant advantages of utilizing megapixel cameras •
Remember the following principles as you proceed in your activities:
DVR/NVR
1
Any image, whether video or photo, requires sufficient detail. Detail is determined by (1) the level of
resolution in the image and (2) the size of the person’s face relative to the size of the image.
2
The person’s face must look directly towards the camera. This affects both the class of imported pho -
tos that are acceptable and how video cameras must be positioned to capture faces.
3
Imported images have to meet the requirements listed above. With the exception of mugshots and
passport photos, most photos do not meet these requirements.
4
Video cameras must be positioned specifically to capture faces. The cost may be inexpensive but the
skill is not trivial. Care must be taken to precisely position cameras to capture faces consistently.
5
Megapixel cameras in your security solution allows a significantly wider field of view but also require
more storage and have a negative impact on the system performance if a proper equilibrium is not
determined.
6
It should be understood that determining the maximum mounting height is not affected by the
increase in resolution of megapixel cameras. The same formula must be used to stay within the 20%
slope specification.
