I have heard that today's WiFi is not a completely secure connection and can be hacked. I've also heard that there is a new camera on the market, and I'm afraid it will be discovered. Can I protect myself? The Dropcam HD WiFi Security Camera is a small webcam that works via USB. It provides HD quality video and night vision. It also supports two-way audio recording and DVR functions. By the way, the webcam is always on and can be accessed through an iPhone, web browser, or Android-based personal device. To prevent this type of private access, many companies are now using WiFi jammers to shut it down.
