Wired security cameras can’t be jammed as easily as they transmit footage to the DVR. If the DVR or transmission cables are damaged, the wired camera might be jammed. On the other hand, wireless cameras are easily jammed by sending strong radio signals of the same frequency which the camera itself uses to operate. It’s recommended that the wires connecting the camera to the DVR are concealed. This way, they’re less prone to damage and from being jammed. Modern security cameras quickly alert authorities or homeowners if the camera fails to record after a given threshold of time.
