Abstract
A method for detecting a video surveillance device includes: obtaining MAC address information and port information of at least one target device that accesses a same wireless network as the electronic device; determining, based on the MAC address information, whether the target device is a video surveillance device; if determining cannot be performed based on the MAC address information, determining, based on the port information or based on the MAC address information and the port information, whether the target device is a video surveillance device; and if determining still cannot be performed, obtaining fingerprint information of the target device by using a TCP port-based or UDP port-based probe protocol, and further determining, based on the fingerprint information, whether the target device is a video surveillance device.
