Always Prepared For Third Party Defects

Our system uses hardware based third party video encoders, in both analog and IP cameras.
I have seen problems in both.

Analog encoder(Stretch S7) hangs occasionally. After days of research, I found it’s caused by a certain range of lighting, when it’s not daytime and not completely dark either.
The fix was to reboot the card when the hardware watch dog detects it.
IP camera (Vicon IQeye 9 series IQB92WI firmware V4.2) hangs ffmpeg HLS segmenter in about three hours, with error “Non-monotonous DTS”.
The fix was to downgrade to the previous version of firmware.

Those are both great products, but there are always corner cases.
A exhaustive test run is the only way to go. No reasoning is enough.
