Required In-Wall Space: 99.8mm (3,93 inches) x 193.88mm (7.63 inches), 35mm deep (1.38 inches)
The thickness of the GDS3710 is 36mm, the in-wall mounting kits need to sink in to allow a little thickness of the face plate so the whole installation will be flushed with the wall.
We do lack experience in designing the “goose neck” or “post” installation scene, sorry about this.
I think all those mounting cases you guys mentioned above should work (beauty is another issue) as long as the back does not have holes and gaps sealed with silicon glue. But of course, the sticking out edge will help, especially the top edge will help prevent sun shining directly into lens to make it useless.
Again, thank you for using GDS3710 and support Grandstream.
