How is AX PRO different from a consumer alarm?

It's not the app. It's what sits behind it:

• 868 MHz radio: the band reserved for alarm use in the UK, far less crowded than the 433 MHz used by DIY systems. Frequency hopping and AES-128 encryption mean signals can't be replayed or jammed casually.
• 64 zones and 16 areas on the DS-PWA64 panel. One system can arm a house, a garage and an outbuilding separately.
• Three signalling paths: wired ethernet, Wi-Fi and GPRS over a SIM. Cutting the broadband doesn't take the alarm offline.
• ARC ready: SIA DC09 (SIA Level 2 and Contact ID), ISUP and ISAPI, with Hik-IP Receiver support and video verification. A monitoring operator can see what triggered an alarm before sending anyone.
• 5,000-event log and 30 individual users, so the record shows who armed or disarmed and when.

Which kit should I start with?

The panel supports up to 8 keypads, 4 sounders, 32 key fobs, 32 tags, 2 repeaters and 48 PIRCAMs.

• Kit 1 includes two key fobs.
• Kit 2 includes a keypad with tag reader.
• Everything else in the two boxes is identical. Choose by how people will arm the system, not by price.

What is a PIRCAM?

A PIRCAM is a PIR detector with a built-in camera. Up to 48 of the 64 zones can be PIRCAMs. When one triggers, the alarm arrives with a picture of what caused it. That turns a possible false alarm into a decision, and it's the feature that sets AX PRO apart from a cheaper wireless system.
