-Vizy can work with two types of lenses -- M12 and C/​CS-mount. ​ M12 is the same type of lens commonly used with action cameras like GoPro. ​ C/CS-mount is often used in industrial/​security applications. ​ Being able to use both types of lenses means Vizy can be used with a wide range of off-the-shelf lenses.  ​Since Vizy has an actuated IR-cut filter, it's recommended that you use lenses that do not have IR-cut filtering. ​ Fortunately,​ these lenses are more common. :-)+Vizy can work with two types of lenses -- M12 and C/​CS-mount. ​ M12 is the same type of lens commonly used with action cameras like GoPro. ​ C/CS-mount is often used in industrial/​security applications. ​ Being able to use both types of lenses means Vizy can be used with a wide range of off-the-shelf lenses.  ​
