While typing in the Telnet window, you may experience so-called echo. This is simply the
server repeating some or all of the characters it receives; it will not have any impact as long

Databases
In the Administrator application's
Camera Settings for [Device Name] [Camera Name] window
you are
able to select which action to take if a camera database becomes corrupted. The actions include
several database repair options.
While being able to select such actions is highly valuable, it is of course even better to take steps to
ensure that your camera databases do not become corrupted:
Power Outages: Use a UPS
The single biggest reason for corrupt databases is the surveillance system server being shut down
abruptly, without files being saved and without the operating system being closed down properly. This
may happen due to power outages, due to somebody accidentally pulling out the server's power cable,
or similar.
The best way of protecting your surveillance system server from being shut down abruptly is to equip
your surveillance system server with a UPS (Uninterruptible Power Supply).
The UPS works as a battery-driven secondary power source, providing the necessary power for saving
open files and safely powering down your system in the event of power irregularities. UPSs vary in
sophistication, but many UPSs include software for automatically saving open files, for alerting system
administrators, etc.
Selecting the right type of UPS for your organization's environment is an individual process. When
assessing your needs, however, do bear in mind the amount of runtime you will require the UPS to be
able to provide if the power fails; saving open files and shutting down an operating system properly
may take several minutes.
