It's about time there is a 16 port POE available. If you install a 16 camera NVR IP network system and you need to power the cameras this beats the heck out of multiple POE switches or local injectors. You don't have to be a professional IT specialist to use it, it's not that difficult and should you have any problems, don't be afraid to call Security Camera King in a heartbeat to ask for help. They'll be glad to help you and won't stop until your problem is solved. I know, because I did. Good product!
