4MP/Varifocal/Starlight? IPC-HFW5442E-ZE, N45DB7Z, Or ??
Hi Andy. I THINK what I want for a base general purpose camera is 4MP / Varifocal / Starlight? Ideally turret but it seems for now bullet may be the only good option? These would fulfill about 17 positions w/ the remaining 10 a combo of PTZ and higher rez fixed focus. These seem good options...- TundraCam

Is this IR reflection?? 5231 varifocal
Disclaimer, I plan on using this 5231 varifocal at full zoom. As you can see, under zero zoom, there is considerable IR blasting the soffit above.

The varifocal Starlight can be adjusted from 2.7mm to 12mm The non-varifocal Starlight is available in 2.8mm, 3.6mm or 6mm, depending on model (if my checking is correct) The Varifocal's motorized lens increases the price, naturally. The adjustability is "worth it", some would argue. But what... -
