More information on solving problems with connection to Stream Vision 2 by following the link.

Possible cause

In positive temperature conditions, objects being observed (surroundings and background) heat up differently because of thermal conductivity, thereby generating a high temperature contrast. Consequently, the image quality produced by the thermal imager will be better.

In low-temperature conditions, objects being observed (background) will cool down to roughly the same temperature, which leads to a greatly reduced temperature contrast and a degraded image quality. This is normal for all thermal imaging devices.

Possible cause

Algorithms that are used for image processing might sometimes cause traces of horizontal lines to temporarily appear on the image. This should not be considered as a critical error.

Possible cause

The Bluetooth module is not turned on.

Solution

Turn on the Bluetooth module according to the instructions (see the Bluetooth section).

Possible cause

The Remote control is not activated.

Solution

Activate the remote control according to instructions  (see the Remote Control Activation section).
