Call

One button, hands-free.

A single call button dials the guard station over SIP. Speaker and microphone with echo cancellation, voice activity detection and G.722 wideband audio keep speech clear.

A line-out port is provided for external audio equipment. Two DTMF-controlled relays let the guard open a gate or boom during the call.

Tough

316 stainless, IP65, IK10.

The 316-grade stainless steel front is rated IP65 against dust and rain and IK10, the top impact level, for unattended public spaces.

210 × 120 × 45.6 mm, −20 °C to +55 °C. Flush-mount with the E21 in-wall box, or surface-mount with the E21 on-wall rain cover. Power from 802.3af PoE or 12–24 V DC.

Answers

Common questions

What is the difference between E21A and E21V?

Same 316 stainless IP65 / IK10 body, button, audio and relays. E21V adds a 2 MP camera (116° × 60°, 1080p) with IR night lighting and a motion sensor; E21A is audio-only.

Can it be used outdoors?

Yes. The front is IP65 and IK10, rated −20 °C to +55 °C. In exposed spots the E21 on-wall rain cover adds a hood.

How is it powered?

IEEE 802.3af PoE, or a 12–24 V DC supply.

How is it mounted?

The E21 is flush-mount: use the E21 in-wall box (190 × 100 × 60 mm cut-out), or surface-mount it with the E21 on-wall rain cover. Both are sold separately.

Can the guard open a gate?

Yes. The two relays are triggered individually by DTMF tones from the answering phone during the call.

How high should it be mounted?

Akuvox's placement drawing puts the button centre no higher than 1,200 mm above ground, with the bottom of the panel at about 1,130 mm.

Is the answering station included?

No. Calls go to any SIP endpoint — a guard-room phone, softphone, PBX extension or Akuvox indoor monitor — sold separately.

An outdoor help point.

Choose E21A when audio is enough — or E21V when the guard needs to see the caller.
