kit to buy

[Superpatpat]

hello and thank you for accepting me on the forum, sorry for my English I take a translator, I am from Quebec and I have been looking for some time to buy myself a good 4 camera kit, I already have reolinks and I think that amcrest is more solid and I read a lot of good comments on the net, I don't want to regret my purchase either so what do you think of the model ip8m-t2499ew-28mm, the only thing I find is that it has just 15 fps are you going to jerk? I want to record 24/7 which nvr I should take because it has a lot of choice and as I said above I want to be satisfied with my purchase and that it works well but I look at the 4 cameras at the same time thank you and I awaits your ideas Patrick
