As far as we are aware there are no TV apps for Hikvision, the only way to get your NVR up on a Smart TV is to hard connect with an HDMI cable or possibly browse to the NVRs IP address using Smart TVs browser. This 2nd option will not work with all TVs and even those that do have browser will not be a user-friendly as a direct HDMI connection and you may have browser plug-in issues.
I've successfully managed to get hik-connect APK on a firestick before. Just Google how to download android apks on a firestick and just replicate for the hik-connect app.
