There are a number of ways to provide "partial" security to a pool cage.  I
emphasize partial because it's difficult to totally protect an outdoor
environment without false alarms.  There's always a compromise.

One method is to use wireless, outdoor motion detectors.  There's a system
called Voice Alert which uses from one to six wireless PIR (passive infrared)
sensors and a dedicated receiver with voice annunciation (you record your own
messages) and relay outputs (for connection to an existing alarm.  The idea is
to provide you with an audible warning but typically no siren if you're home
and someone enters the lanai.  When you're away you might want the main siren
to also be triggered on entry.

Most folks recommend against sending a signal to a monitoring facility based
on outdoor motion due to the higher incidence of false alarms from this type
of detector.  If you plan to do that, you might want to consult with local
authorities first.  There may be local regulations prohibiting it.

Other types of detection that can be made to work with a bit more effort
include magnetic contacts on the screen doors, infrared beam detectors around
the perimeter and even floating sensors to detect a splash.  Note that the
floating sensors, which are primarily used to protect against accidental
drowning, are not UL listed and rarely meet state code requirements for the
purpose.

Speaking of codes, Florida, California and several other states now require
pool alarms on the doors and windows leading from the home to the pool area.
This is intended to help avoid toddlers drowning.  The detectors are wired to
the doors and windows and set to give an audible warning inside the house if
someone opens a door to the pool area.  Some provide a 7-second delay so you
can re-enter while others utilize a separate button mounted on the outside
wall above the reach of a child, to temporarily disengage the sensor before
opening the door.  None of these pool alarm systems are 100% effective but
they do help when used properly.
