Do I have a bad imager?

This is a technical article.

Testing your imager using telnet

IQeye cameras have the capability for the user to test the imager without involving the JPEG encoding hardware. This is done by running a command in the telnet environment.

Make sure the camera is not accessible by viewers, as this will conflict with an accurate imager reading.

1. Log into the camera over telnet, in a terminal. Set 'user' as the username, though this doesn't matter at all
   telnet <ip of camera>Username> user
2. Escalate to the privileged user
   Local_2> set privileged
3. Enter password "system" by default, you'll get the double-caret 
4. Local_2>> test framerate imager36 images in 5 seconds = 7.2 fps

You should get a framerate that matches the specs on your camera.
If your frame count is 0, even after resetting the camera, the imaging board is likely bad and will need to be replaced.

Here is a picture of the back of an imaging board for an IQ7xx series camera, and the front, showing the image sensor behind the movable IR filter.

The bottom circuit board of the camera plugs in perpendicularly into the exposed connector on the back of the imager board.

The IQ752 has a sliding-style IR filter assembly.
