Your not really going to see spiders building more webs on the TVI eyeball camera then on the IP turret, real life they will spin a web a few inches infront of either between the soffit and the wall - rain/sun visor on a bullet on the otherhand you'll have all sorts living in there.
There's some nice TVI dome cameras built on the same chassis as IP version as well so the choise isn't just turret or eyeball - just make sure you get the correct lens and ask Dynamic what they can get from Amsterdam/Holland - you'll get more choice as long as you know what you want (i.e. lens), check out the specs on the D8T line, thats what i'd be looking at for good 1080p nightvision - 5MP is also readily availble and 4K starting to come through
Hikvision UK & Ireland
Check out the HTHI-K recorders
Hikvision UK & Ireland - that one is a 6 channel - 4 analogue (upto 4K@12fps) and 2 IP (upto 4K), H265 encoding, etc. coax (i.e. RG59 or RG6) will give you the best picture and least amount of interference but if you want to hedge your bets a roll of
cat5e is cheap, run that out to the same location for redundency - keeps everyone happy.
No prices for that recorder yet (just been released) but also worth checking the Power over Coax (PoC) recorders for an easy less wires install.
