Hi

i have one Tapo but about 12 cameras on an old dvr system. 
 

It is for business use.

If I  replaced them all with Tapo would that work, is there a way to watch all cameras on the app sequencing through 1 camera to the other?

or is it just a bad idea?  Cost of Tapo is so good it would save so much rather than getting a new nvr and re working  all cameras.

thanks
