RLK8-800V4 with RLC80A Cameras. God choice ?

Torzen

Hi
I need good advice in connection with choosing an exterior surveillance system for my single-family house.
I need to mount cameras on the underside of a horizontal eaves that extends approx. 50 cm. I am considering a system RLK8-800V4 with RLC-840A cameras as I want a wide POV and I want audio in and out. I think I want constant recording. I am considering this camera as it is a dome camera. I think it is more discreet than a bullet camera.
Is it a good choice? Anyone have good or bad experiences with this setup? I know it is a difficult question, but it is difficult to assess the advantages and disadvantages of the many models.
Thanks in advance
