If you are looking to mount a camera without drilling holes, there are several methods available. One option is to use adhesive mounts that are specifically designed for this purpose. These mounts typically come with an adhesive backing and can be attached directly to the wall or ceiling without damaging it. Another option is to use tension-mounted brackets that attach using tension rather than screws or nails, allowing them to be easily removed when needed. Finally, some cameras may have options for mounting on tripods or monopods, which offer more flexibility in positioning the camera and do not require any permanent installation at all.
