Replace my Lorex 4K (lnb8005) with a starlight (IPC-HDW5231R-ZE)

thx... I will pull the trigger then. Thanks.
Is updating the firmware a difficult process?
 
Sorry, more questions... Thanks in advance for the help!
I was just on Andy's site and saw the IPC-HFW4239T-ASE. Other then the bullet vs turret, how do these compare (IPC-HDW5231R-ZE vs IPC-HFW4239T-ASE)?
 
Thanks... What are the major benefits to Turret vs Bullet besides aesthetics?
The shape of the turret usually makes it more difficult for spiders to spin webs across as well as for folks to jump up and pull on (attempting to change how its aimed).
 
From what I’ve read, the 5216 seems to be the most popular. They have 2 or 4 Hard drive bays and with/without PoE available. Heres a link to comparison thread of the 42xx vs 52xx nvr s NVR 4116HS-4KS2 vs 4216 vs 5216

I’m in the same boat with the Lorex deal, but I don’t think I can justify spending the money for the ivs/ autotracking features. Plus I’d have to buy the PTZ1A225U-IRA-N 2MP 25x Starlight
