Below is a list of differences between the E46 pan tilt unit (PTU) and the D47 PTU:

• E46 is IP65 rated (weatherized version), less than the D47 (IP66)
• E46 supports Ethernet connectivity
• E46 includes Geo-Positioning Module (GPM)
• E46 controller is separate from the PTU head assembly
• D47 is IP66 rated, so is better suited to extended outdoor use
• D47 does not support Ethernet
• D47 does not include GPM (it is an optional accessory)
• D47 controller is integrated as the PTU base
