Choosing the right lens in catching Fire and Smoke
There are 2 types of cameras used in Verifire one is the bullet camera and the other one is a box camera. The difference between the 2 is that the bullet has a fixed or irreplaceable lens while the box camera has a detachable lens. This makes the Verifire Box camera special because it can be used in greater distance in catching or monitoring fire and smoke.
The Verifire indoor box camera can switch lens easily by unscrewing lens which has a CS-mount standard thread from the front part of the unit. You can decide which lens to use on your initial purchase. Initially the Verifire box camera kit comes with a non-IRIS ½.5” 3 Mega 3.3 – 10.5 mm F1.4 CS mount (model # TV033105M.IR).
Lenses available for the camera has 2 types:
- AUTO IRIS – it automatically adjusts the F value or aperture of the lens making the image more visible and brighter. The price is more expensive than the non-iris model.
- NON – IRIS – it has a fixed F value or aperture. This is typically used for areas with consistent lighting or brightness.
Focusing on these, the lenses are not an issue since the Verifire lenses are wide angled and have very good focus. However you need to focus it on the area where the fire or smoke might occur.
