Baseus Heyo Series II is a compact, palm-sized security gadget that scans for hidden cameras using both infrared and optical filters, powered by a high-sensitivity 3D sensor chip. It offers multi-mode alerts (sound, red LED flash, and vibration) and can hang on door handles for instant intrusion warnings. An inbuilt LED flashlight adds utility. The rechargeable 60mAh battery lasts up to 6 months standby, and it includes a handy USB A to USB C cable for charging. Weighing just 15g, it is a budget-friendly privacy device you can carry anywhere.
