Look for wifi IP camera using Camhi app, they can tapao your Tapo or Xiaomi any time in terms of picture quality. Make sure it's either Sony IMX335 CMOS sensor for 5Mp or IMX415 for 4k.

If for serious security not recommended, this type of battery camera only wake up and record when the PIR detected motion to conserve battery. You will have many missed recordings because there is no 7/24 recordings or event pre record options like conventional cctv. Not too sure about Xiaomi but you better check with seller first about this.

Is your reolink camera outdoor or indoor? Seems firmware update solved the night time ghosting image?

Actually, I have second opinion on Tapo. An associate share 2 tapo cam recently install in one F&B outlet, model C210, was not bad at all for only RM160. And I was in Lowyat Viewnet today the sales mentioned that the 4Mp Ezviz(HIK) is even better. Maybe you can look it up.
