12 Vdc Wire Gauge and Transmission Distance
The following table shows the recommended maximum distance adopted for the different wire sizes
when the 12 Vdc voltage loss is less than 15%. For example, for a device with the rating power of
20 VA which is installed 77 feet (22 m) from the transformer, the minimum wire gauge required is
1.0000 mm (18 gauge).

Using the Waterproof Ethernet Fitting
Install the Waterproof Ethernet Fitting on the Ethernet cable end at the camera when moisture
or contamination exists in the area near the camera. The fitting includes several parts that must be
installed in a specific order. To install the fitting:
1.
Place the rubber O-ring over the camera drop cable end cap.
Push the O-ring up to the connector cap.
