## Abstract

A camera comprising a housing, a lens, a lens holder and an image sensor is provided. The image sensor is supported by the lens holder. The lens holder comprises a through-going channel configured to coaxially and lockably receive the lens in a position in which a rear end of the lens faces the image sensor. The lens holder is spring loaded in relation to the housing by an elastic member arranged in a position between the housing and the lens holder into a position in which a front portion of the lens is forced into abutment with a first lens stop arranged in the housing, thereby providing a fixed axial distance between a front end of the lens and a front end of the housing.

## Claims

### Claim 1

A dome camera comprising:
a housing, a lens, a lens holder and an image sensor, wherein:
the image sensor is supported by the lens holder;
the lens holder comprises a through-going channel configured to coaxially and lockably receive the lens in a position in which a rear end of the lens faces the image sensor;
the lens holder comprises an axially extending neck portion and a rear end of the neck portion is provided with a radially extending flange;
the image sensor is mounted to a rear surface of the radially extending flange such that the image sensor is arranged to face the lens supported by the lens holder; and
the lens holder is spring loaded in relation to the housing by an elastic member arranged in a position between the housing and the lens holder into a position in which a front portion of the lens is forced into abutment with a first lens stop arranged in the housing to provide a fixed axial distance between a front end of the lens and a front end of the housing.

### Claim 2 (depends on 1)

The dome camera according to claim 1, wherein the housing comprises a through-going channel configured to coaxially receive a portion of the lens holder, and wherein the first lens stop is arranged in a front portion of the housing encircling a mouth of said through-going-channel.

### Claim 3 (depends on 2)

The dome camera according to claim 2, wherein the front portion of the lens is configured to project past a front end of the lens holder in a condition when the lens is lockably received in the lens holder, and wherein the front portion comprises a radially extending flange, a rear portion thereof being configured to abut the first lens stop as a result of the lens holder being spring loaded.

### Claim 4 (depends on 1)

The dome camera according to claim 1, wherein the front portion of the lens is configured to project past a front end of the lens holder in a condition when the lens is lockably received in the lens holder, and wherein the front portion comprises a radially extending flange, a rear portion thereof being configured to abut the first lens stop as a result of the lens holder being spring loaded.

### Claim 5 (depends on 4)

The dome camera according to claim 4, wherein a rear end portion of the inner envelope surface of the through-going channel comprises a second lens stop.

### Claim 6 (depends on 1)

The dome camera according to claim 1, wherein the lens is configured to be lockably received in the through-going channel by a threaded engagement between an inner envelope surface of the through-going channel and an outer envelope surface of the lens.

### Claim 7 (depends on 1)

The dome camera according to claim 1, wherein the lens is configured to be lockably received in the through-going channel by a bayonet coupling between an inner envelope surface of the through-going channel and an outer envelope surface of the lens.

### Claim 8 (depends on 1)

The dome camera according to claim 1, wherein the elastic member is a spring, preferably a coil spring or a leaf spring.

### Claim 9 (depends on 1)

The dome camera according to claim 1, wherein the housing forms part of a tilt unit.
