Thoughts on these 20x optical zoom cameras?

[P6RAF]

I'm after 5/8MP 20 x Optical zoom cameras. After 2 days of YouTube reviews and various Web searches this is a handful of options...
Asecam 8mp 30x (£150+vat) PoE + wifi
Annke (hz500or l51CK2)/Sannce 5mp 20x ptz £80 no PoE
JideTech P2-20X-5MP4G (£209) wired only
Anpvis (£219)wired only
SV3E(£169)no PoE
Unbranded hikvision copy £165 PoE + Wifi
Any others I should consider?
Ideally my budget is £200

Are you going to use them standalone or connected to an NVR - depending on the NVR some will support more functions than others.

I have Hikvision NVR's where the Jidetech will only work on Onvif - and other non Hikvision cameras the same - but if your NVR has certain functionalities you might be better off getting something that connects more easily and allows a few of the smart features to work (like intrusion detection and line crossing).

Do you 'need' an 8mp camera? If you're connecting to an NVR - check that it can take it at full stream/resolution based on what you've already got connected.
