Visonic alarm interface or complete zwave alarm?

Hi guys,

I m asking myself if there still a sense to have an Visonic alerm with a Vera interface, instead to have a complete alarm done in Vera?

What do you think?

The actual difference is that the alarm produces, like Visonic, has alarm specific produce like keypad with pin code or small remote to activate/deactivate the alarm that in zwave alarm are still missing.

What do you think in term of reliabilty?

Thank you for your answers
Regards
Matteo
