I discovered this product after
I discovered this product after changing to an internet provider that did not allow port forwarding for remote access to the NVR. Replacing the entire camera system was not an option. I spoke with sales rep and technical support to make sure they understood my needs and both said I could setup remote viewing using their free app. I remained skeptical. My first surprise was how cost effective the product was and the second was that I received the product 4 days early.
Setup did not take that long and behold, they were correct - I could access the system remotely without having to setup port forwarding or making any modifications to my router. Exactly what I had hoped for. Thank you.
