Resolution Tips
The following tips prolong your unit's archive of video through lowering the resolution of recorded
video.
Do you need to establish an individual's "presence" or a person's identify?
Presence may be sufficient. For tasks that only involve establishing if "someone has entered
the building", or counting cars in a parking lot, and so on, low resolution may be "good
enough" to establish presence, helping to guarantee a longer video archive; see figure 5–13.
How many cars? Objects can be effectively counted at low resolution make using high
resolution unneeded.
Identification is needed. Unknown vehicles, a person's facial traits and so on, camera position
and higher-resolution may be needed. Identification may not be as crucial when subjects are
known: employees, uniformed personnel, and so on.
You have the option of adjusting Microsoft Windows' Display Properties for your PC monitor.
