Security technology systems should be configured with an alternative
power source that will allow the systems to continue to operate in the

A criminal trying to breach your security may attempt to
disable the power to your security technology in order to

An alternative power source may be an auxiliary power

generators may also be used for other critical systems such
This is only a SHOULD requirement for CTPAT.
So you should use a UPS with the security technology.
Duh!! Common sense should win out here. Keep security systems running for as log as possible in any scenario.
