You can use this universal junction box with some of our full size Sibell bullet and vandal dome cameras. This is a great way to avoid having to drill through a wall to protect your connection since your connection will be hidden inside the junction box! This is meant to be used with the IPOB-SB4IRZA, IPOB-SB5IRVA, IPVD-SB4IR.
Originally used a standard electrical junction box, on a whim I opted to try one made specifically for my camera. Now all my cameras that need a box have the Sibell Junction Box. The product looks better than a typical electric box and provides a cleaner install appearance. Would highly recommend it.
