The most prominent two features are as follows:
- Vari-focal auto iris lens. A dome camera with built-in lens usually has a fixed iris and fixed focal, mostly board lens.Fifo Optics improve this point with vari-focal auto iris lens so that the user can obtain a much wider surveillance area and a clearer image. Otherwise this kind of camera is applicable to many many situations including those where the illumination is changed frequently, because this iris can open and close automatically.

- Waterproof vandal dome. The narrow design and metal cover can effectively protect the camera not to erode by water or be broken by the outside force, so it has a longer life time than the average camera according to Fifo Optics.
