Pulsar studies are generally carried out at centimetre wavelengths and high-energies (X-ray, Gamma-ray), where pulsars are brighter and the available instrumentation is well adapted to fast time-domain science. In the last years, pulsar astronomy in the millimetre band has intensified, supported mainly by large-bandwidth instrumentation with fast-sampling capabilities at the IRAM 30-m telescope. However, receiver and backend combinations suitable for pulsar observations at (sub)millimetre facilities are rare. In this contribution, we will discuss a novel application of continuum cameras to pulsar astronomy in the (sub)millimetre range, which offers a new possibility to enable pulsar observations with high sensitivity at observatories where these type of receivers are (or will be) available. This promises to extend the spectral window in which pulsars can be studied, often with minimal or no extra modifications to the original hardware. Two proof-of-concept experiments will be presented, showing detections of a radio magnetar with the NIKA2 KID camera on the IRAM 30-m Telescope, and the SCUBA2 TES bolometer on the James Clerk Maxwell Telescope.
