Andrew from Iscam/Comfort has given me some useful pointers and suggests
(which I have read elsewhere, eg alt.security.alarms) that dual tech
sensors are less reliable than standard PIRs, and that quad PIRs and mirror
optics are both worthwhile features.  I hadn't realised that Iscam also
sold the sensors, so I can probably get the lot from a one stop shop...

Thanks for the suggestions,

Nigel
