Ah, the elusive mobile phone detection camera range—it's not like these devices come with a glowing neon sign saying, "I spy on your phone!" Typically, these cameras rely on detecting radio frequencies emitted by mobile phones, which usually means a range of about 10 to 50 metres, depending on the environment and the sensitivity of the equipment. Walls, furniture, and other electronic devices can muck about with the signal, reducing that range significantly. For a more precise figure, you'd want to check the specs of the particular model, as some high-end gear can stretch its detection up to 100 metres in open spaces. Naturally, the effectiveness also depends on whether the phone is actively transmitting data or just idling in airplane mode.
