Handling Precautions and Camera Care
Opening the camera housing will cause damage and will void the hardware warranty detailed in the beginning of
this document. Since the Allegro Camera is a precisely manufactured device it must be handled with care. Some tips
for device care are below:
1. Electrostatic charging should be avoided
2. Avoid touching the lens when handling the camera, as fingerprints will affect the quality of the image
produced by the device.
3. When cleaning the lens do not use excessive force and please use a standard camera lens cleaning kit or
clean dry cotton cloth.
4. Avoid exposure to bright sunlight, dusty environments, rain etc. as this may cause problems with the
electronic and optics of the system.
5. Mishandling of the device such as excessive shaking, dropping and force should be avoided.
Case Temperature and Heat Dissipation
For the camera to function correctly, it is required to provide sufficient heat dissipation for the internal operating
environment. Since the camera electronics are neatly packed into a small space it can become very warm to the
touch when running in some modes; this is expected behavior and will not damage the electronics.
The use of a cooling fan to set up positive air flow around the camera in order reduce is suggested. Please take into
consideration the following precautions:
1. Mount the camera on a heat sink that is composed of a heat conductive material like aluminum, such as a
camera mounting bracket.
2. Ensure the flow of heat from the camera case to the bracket is not blocked by a non-conductive material like
plastic.
3. Provide enough space around the camera to facilitate the free flow of air.
