Ceiling vs. wall mount guide

Avia supports both ceiling and wall mounting. The right choice depends on your store's physical layout and the position of your entrance.

Ceiling mount (recommended)

Ceiling mounting is the preferred option where possible. A ceiling-mounted device looks directly down into the entrance, giving the widest and most symmetrical field of view.

Best for:

Standard retail entrances with overhead clearance
Entrances up to 4m wide
Locations where wall space is limited or obstructed

Requirements:

Ceiling height between 2m and 5.5m
Device mounted directly above or within 30cm of the center of the doorway
Clear sightline downward — no signage, railings, or fixtures blocking the view

Wall mount

Wall mounting is used when ceiling access is not available or practical — for example, in entrances with very high ceilings, glass atriums, or structural constraints.

Best for:

Atriums or spaces with ceilings above 5.5m
Entrances where a ceiling mount would be off-center
Retrofits where ceiling cabling is not feasible

Requirements:

Mounted on the wall above the entrance, angled downward
Height between 2m and 5.5m (measured to the device, not the ceiling)
Device aimed toward the center of the doorway

Key differences

	Ceiling mount	Wall mount
Field of view	Symmetric, directly downward	Angled — requires angle adjustment in app
Installation complexity	Standard	Slightly more involved (angled bracket)
Recommended for	Most stores	High ceilings or no ceiling access

Important: During app setup, you must specify whether the device is ceiling or wall mounted, and enter the correct height. Entering incorrect values will affect counting accuracy.
