I'd assume app rather then monitor ?
I'd probably use a Orisec CP20 + The Keypad with the big display, wireless access point on the panel, orsiec radio devices & pyronix deltabell
Or a Texecom 64-w + blue lcdp + radio devices, smartcom + deltabell
Or a euro 76, radio zem, wireless wifi card, euro keypad, euro radio devices & a deltabell
Orisec is probably cheapest equipment cost & euro the dearest,
