Our wireless hidden cameras blend into any environment, at home or in a work environment, and come in a wide range of form factors — from smoke detectors to a hidden wireless camera in a clock radio. Virtually undetectable, our covert wireless security cameras are ideal for undercover surveillance and investigations, even in low light. Select cameras work together, allowing you to create an effective covert wireless surveillance system with up to four cameras per receiver. These cameras support quad-viewing, so you can live monitor up to 4 hidden cameras.
