Housing and hood in one.
The AK-E21ONH is Akuvox’s E21 on-wall mounting rain cover. The E21A and E21V are flush-mount only; this silver housing carries the unit on the face of the wall and its hood keeps rain off the faceplate.
This SKU is the on-wall housing only.
You receive the silver E21 on-wall mounting rain cover. The E21A or E21V is sold separately.

A help point where you can’t chase the wall.
Precast concrete, tiled walls, posts and existing car-park structures often can’t take a 60 mm-deep cut-out. The on-wall housing puts an E21 there anyway, with weather protection built in.

Housing
A surface box with a hood.
The housing fixes to the wall and the E21 mounts into it, so the flush-only unit can go on a surface. The hood covers the top and sides of the faceplate.
A cable entry in the back lets the network cable come straight out of the wall.
Fit
For E21A and E21V.
Both E21 models share a 210 × 120 × 45.6 mm stainless steel faceplate, so the same housing suits the audio-only E21A and the camera-equipped E21V.
Where you can cut the wall, the E21 in-wall box gives a flush finish instead.
