There are a few ways to block the signal of a surveillance camera. One way is to use a wireless signal jammer. This device emits radio waves on the same frequency as the camera’s signal, disrupting the communication between the camera and its receiver. Another option is to use a Faraday bag or pouch, which blocks electromagnetic fields and can be used to store the camera, preventing it from transmitting data.
It’s important to note that using signal-blocking devices may be illegal in some jurisdictions, so it’s important to check local laws and regulations before using them.
