Hikvision offers a wide selection of PIR cameras ranging from 2MP to 5MP, available in both bullet and dome forms. These cameras not only detect, but also help deter would-be intruders by triggering visual or audio alarms. With up to a 11m detection distance, the PIR camera covers sufficient areas no matter you need it for an open space, for example a warehouse, or a confined area like the entrance of a store.
