When used on a 1/4’’ sensor, CH2504 will produce a circular image like this →
with a 205 degrees view，while CH3631 will form a full horizontal one like this →
with a slightly smaller view angle as194 degrees. Both lenses have their advantages. CH2504 features all glass design mounted in a aluminum housing, which makes it heat resisting. CH3631 is IP69 rated against dust and water,which means it can be used both indoor and outdoor, and its 8.8MP high resolution enable users to get sharp images. Like all other fisheye lenses, images obtained from the1/4’’series fisheye lens have a barrel distortion where the centre of the frame appears to bulge outwards.However,they provide a large depth of field. The image below was captured by CH2504 (it was compressed as uploaded).
