+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.
