Hikvision DS-PS1-I-WE(B)/Blue AX PRO Wireless Internal Sounder

The Hikvision DS-PS1-I-WE(B)/Blue is the AX PRO internal sounder — a compact indoor siren with a blue LED flash, for alerting people already inside the building rather than the street outside.

Why an internal sounder matters

The external sounder tells the neighbourhood something's wrong; this one makes sure anyone inside the building hears it immediately — a landing, a hallway, a shop floor — without waiting for a phone notification.

Compact and indoor-specific

At 88 × 88 × 32 mm and 169.5 g, it's a fraction of the size of the outdoor unit, with no IP rating needed for an indoor location. A blue LED flash accompanies the alarm sound for extra visibility.

Three years on batteries

Up to three years standby.

Radio built for alarms

868 MHz two-way, 2GFSK, free-space range 1.6 km.

Worth knowing before you order

This is the indoor sounder, not the outdoor one. For a wall-mounted external siren, use the DS-PS1-E-WE instead — that one is IP65 rated and considerably louder for outdoor coverage.

Also available in red — DS-PS1-I-WE(B)/Red.

It needs an AX PRO panel. Part of the AX PRO system only.
