This depends on the situation and the purpose of the set-up. The zoom lens gives a much smaller but more detailed image. The wide-angle lens gives a better overview, but everything seems further away, so you see less detail. A wide-angle lens is therefore ideal for close-up pictures in particular, because with a zoom lens there is little image left in close-up. When monitoring a relatively large object (a holiday home or a wide driveway, for example) with one camera, a wide-angle lens can be a good solution. The majority of our cameras have a zoom lens and this is considered the 'standard' lens.
