2.9.1 CS Mount Version

The M22M-Sec-CSVario is delivered with a CS

mount and a compact L24-L54 1/2" vario lens. To

protect the lens against the weather, this version

comes with a longer lens cover (43mm inside,

53mm outside) with integrated glass pane and

threads for an external filter (40.5mm x 0.5mm).

This cover will work for lenses, which have a maxi-

mum diameter of 36mm and which are not longer

than 43mm.

Because of the image sensor's size of 1/2", you can only use CS and C mount lenses

(C mount lenses with adapter ring) for 1/2" sensors or larger. Using other lenses will

produce shadows at the image borders and will reduce image sharpness. Vario

lenses are not maintenance-free, they are definitely less robust and less reliable in

the long run as compared to the MOBOTIX M14 fixed lenses. This is why the vario

lenses are typically used in applications where locations are changing frequently, e.g.

in industrial applications.

2.9.2 Lens Cover with Glass Pane

As an additional accessory, a heavy-duty lens

cover with a front glass pane is available for the

M22M models. This will improve the durability of

the lens cover when used in rough conditions (at

the sea, in sand storms, etc.). This lens cover also

has a thread size that fits external filters

(40.5mmx 0.5mm) available from photo shops.

For example, you could install a polarization filter

to cancel out the reflections from windowpanes or

windshields.

Using this lens cover together with the L22 Super Wide Angle lens is not recom-

mended, since this lens cover produces shadows at the image borders.

Make sure that the white ring remains in the lens cover, since the ring

reduces light reflections and prevents the camera LEDs from adding

reflections to the images.
