Gideon received several Browning BTC-7-4K-Edge cameras from the field. The cameras were dead on arrival. The objective was to find the cause of failure.

The batteries were replaced with new ones. The camera did not turn on; however, when it was disassembled, the full voltage resided at the solder joints of the printed circuit board.

## Conclusions

- Electrical characterization showed many resistors were shorted due to corrosion across the terminals.
- The camera maker did not adequately protect the PCB by applying a conformal coating, nor did they use a proper flux such that no leakage current from component to component would flow during operation. Flux cannot have ionics or aggressive halogens.
- Because the camera maker did not take these steps, the relative humidity, coupled with a lack of standards and methods, caused these cameras to fail.
- We would not advise buying these cameras because of the manufacturer's lack of understanding, training, or planned obsolescence. Whatever it is, the cameras need to be replaced.
