Junction box for eufy floodlight Cam e340

I have eufy floodlight Cams e340, looking for junction box, ideally outdoor, water resistant/proof, robust.

Can anyone recommend one?

Here’s two that work really well to provide a flat surface for cameras to mount to…

#1: This one is deeper and has more room for wires. It also has side ports to allow additional connections. Very high quality: 8161TR Security Camera Mount

#2: This is the one I used for my Floodlight E340 because I didn’t need the extra features of the one above: iMBAPrice 8161-1 Security Camera Mount
