For reference, this is the 2.7mm-12mm varifocal turret vs the 8mm-32mm bullet.Thank you for the explanation, that'll help narrow it down. Most variable zooms top out at 12 to 13.5mm. Searching now for some that will approach 50mm.
This was my coverage of the back gate with a T5442T-ZE (12mm) on the 2nd floor soffit. The install height was 20-22' with a horizontal distance to the gate of 85'.
This is the replacement B5442E-Z4E (32mm) at the same 2nd floor soffit install location.
This is after I moved it down to the deck roof. The new distance is 11' install height with a horizontal distance of 65'.
