Mounting points
The mounting points position and size is illustrated in the section above.
The following mounting points are available:
Four M4×10 points in front panel of the camera (the side of the lens mount).
Four M4×10 points in back panel of the camera.
Housing
CORSIGHT is offered with a IP67 housing (solid particle protection: dust tight, liquid ingress protection: immersion up to 1m).
Lens mount, optical head
All the models are equipped with a C-mount optical head (1–inch thread diameter, 32 threads per inch, 17.526 mm flange back). CS-mount version (identical, only with 12.5 mm flange back) is available on request for high volume OEM customers.
Integrated strobe ring
The CORSIGHT camera can be optionally equipped with an integrated strobe ring that can be software-controlled directly from the camera's feature interface.
Contact NET to learn the available strobe ring types and their specifications.
Sensor
Sensor types
Progressive scanning
All NET cameras provide progressive scan video output. The camera outputs full frame data in sequential order (no field interlacing).
CMOS: global vs. rolling shutter
Some of the cameras with large CMOS sensors are equipped with a rolling shutter. In contrary to the global shutter, where all camera pixels are exposed at exactly the same time, with rolling shutter the exposure of every single line is slightly time-shifted relative to the previous line. This requires some special considerations, especially when capturing moving objects. Flash illumination is desirable.
IR-cut or AR filter
All cameras have by default an IR-cut (color) or AR (mono) filter mounted on top of the sensor. The user has however an option to choose from different configurations:
IR-cut filter with 650nm filter mounted on top of the sensor
Clear glass filter (of the same size as the original IR-cut filter) mounted on top of the sensor. Check, whether you don't need special lens designed for specifically for use without IR-cut filter (common lens might not focus properly in the infrared band or show other problems).
Daylight blocking filter.
Without any sensor cover mounted. This has impact on optical properties of the camera — the C-mount flange distance from the sensor is accurately adjusted for the use of the IR-cut filterand removing the filter decreases the length of the optical path. With some lenses and working area setups it can become impossible to focus properly.

Changing or removing the filter
| Note |
|---|
The filter is accessible from outside the camera and user can change it without loose of warranty. It is very important to do this operation with maximum care so that the image sensor cannot be damaged. If exchanging the filter for another type, it is highly recommended to choose a filter of the same size, not to change the optical properties of the system. Removing the filter completely will change the length of the optical path which can lead to focusing problems in some scenarios. To mount/dismount the filter, you will need a hexagonal screwdriver number 1.5. The fixing screws are M2×3. It's important to keep in mind that when changing or removing the filter, not only can be the sensor damaged, but also dust or other dirt can get inside the camera and especially on top of the sensor itself. It is necessary to perform such operation in appropriately clean environment and using suitable tools preventing any sensor dust pollution. |
