[Ticket Question] Wireless House Alarm

[Secware]

My wireless home alarm system has been jammed by source unknown. I have reset it but would like to back it up with hard wired system, not susceptible to jamming, for the upper floor of my house.
Could you suggest components for such a system. I would like it to include

Two PIRs (no need for pet friendly type)
A remote wired keypad which can be set/unset easily without keying in a four number code ( I would like to either press one button or use a proximity tag, unless its operation can be jammed)
A panic button (unless its operation can be jammed)
Outside bellbox with battery back-up (not Odyssey)
Thanks
