hikvision indoor wifi ptz camera for nvr.

[Enigma84]

Hi guys. I need advice. i'm looking for a hikvision camera (indoor), ptz and wifi to use with a hikvision nvr.
I'm not sure about DS-2CV2Q21FD-IW but anyway seems impossible to find in a online store.
I'm open to any advice brand/model but hikvision nvr compatibility is a must.
thank you
