I selected the GDS3710 because it seemed robust and they claimed it came with IP66 certification:
“The IP66 certified weatherproof casing will also protect the device from all conditions including rain, snow, sleet and hail.”
I installed it at my gate on a post that offers protection for the unit on 4 sides, as a typically gate entry post does. I followed their instructions; using the rubber gaskets and the frame back cover. Everything worked perfectly for 2 weeks until we had one rain storm and now the speaker and microphone don’t work (neither during a call or the keypad tones).
I emailed their “Engineering” support, and a guy named Daniel responded:
“Did you remove power from unit during this period of Rain time ?
According to :
Pag 3 > http://www.grandstream.com/sites/default/files/Resources/GDS3710_QIG.pdf
• Do not expose this device to temperatures out the range of
-30 °C to 60 °C for operating and -35°C to 60°C for storage
• Do not expose this device to environments outside of the
following humidity range: 10-90% RH (non-condensing)”
#1 I can’t believe they actually tried to claim that rain and RH are even close to the same thing, and implying it is somehow my fault for not unplugging an outdoor unit during a rainstorm.
#2 I can’t believe this unit is so junky that you can’t install it outside and expect it to survive one rainstorm when they claimed IP66 certification.
Has anyone else had similar problems, or did I just get a defective unit?
