Use outside of the specied conditions

could cause the device to fail and/or

function incorrectly. These conditions

are applicable for the environment

immediately around the device under all

operational conditions. When used with

an external enclosure, active temperature

control and/or other cooling solutions are

recommended to ensure that the device is

maintained within these ranges.

6.1 Installation Recommendations

1. When using an external housing around the camera for

dust proong, use foam inserts or rubber gaskets between

the front of the camera and the external housing.

2. Avoid the application of external forces to the camera

chassis during the installation process.

3. Disassembling the chassis and mounting brackets will

void the warranty.

6.3 Transmittance Requirements

1. Optical transmittance: 400nm-1050nm global

transmittance at each point is above 95%.

2. Blue-purple region, 50% transmittance, corresponding

wavelength less than 395nm.

3. Material atness requirements of front cover

lens:<0.005mm.

4. Glass is recommended.

The current light transmission of the Astra 2 front cover glass lens is as

follows:

Before changing the structural design of the camera, the protective lens in front

of the camera lens must meet the requirements above.

6.4 Cable Design Guide

It is recommended to use the included USB Type-C cable. If a longer cable is

needed, please select a USB certied cable that supports both power and data

(1-1.5m length is recommended).
