Help me pick an outdoor security camera

Currently using Tp-link Tapo C420S1.
It works, but there may be cheaper alternative?

There is a conversation that is dedicated to the subject if you use the on page search box

See below for sub-£55 suggestions from relative last weekend.
Will need to click through to Amazon listing pages to see true prices as the Keepa pages don't always show certain discounts:

Cheapest fulfilled-Amazon likely £25.49 via 25% on-page discount/promo code. Decent 2k resolution 3MP (QHD 2560x1440). Uses excellent Cloudedge app so if using recent firmware it may include ongoing free rolling event cloud storage (in addition to any free sub trial) to compliment the integral microsd storage option (otherwise: and/or sub cloud):

closely followed by another 2k model at £26.99 FBA using respected Wansview app.

£29.99 FBA via on-page £8 discount tickbox. Likely the best option for definite ongoing free rolling event cloud storage using Vicohome app where PIR-triggered event recording duration can be selected as can the cooldown/sleep period between event triggers (can be set to zero, unlike other free storage providers that put zero-sleep option behind paywall). 1080p, integral spotlights, etc. The AI nonsense and some other features are paywalled, but doubt anyone would need to know if it was a cat or a car knocking at the door

£29.99 FBA 2k res. CloudEdge app, and DE reviews mention the free rolling event cloud storage.

£32.40 FBA for 2k res with solar recharge panel. Uses O-Kam app so again may include ongoing free rolling event cloud storage. Was £28 last week

£39.22 via Amazon itself for another Vicohome app cam with ongoing free cloud storage. Includes solar recharge panel. 1080p.

£38.39 FBA 1080p pan+tilt+zoom including solar recharge panel. Vicohome app cam with ongoing free cloud storage.

If that's too cheap, Amazon will directly shift you a re-brand at £110.20 :

or if wanting same solar PTZ cam but with 2k res:
£53.99 FBA keepa.com/
