As recently as five years ago wireless products were kind of iffy when it came to reliability. But due to tremendous advances in technology they have become very reliable-almost as reliable as their wired counterparts.
Nowhere is that reliability more evident than in the wireless spy camera area. You could hardly even find a wireless spy camera six or seven years ago. Like many other products spy cameras have undergone a technological revolution. Wireless spy cameras are so commonplace anymore that the wired versions are almost obsolete.
A good example is the Car Key Spy Camera. It looks just like a set of car keys on a remote key fob but is a spy camera with a 4 GB DVR built-in. It also has a tiny microphone so you can record audio as well.
It is easy to use and easy to carry because it has a key ring attachment. It uses a rechargeable lithium-ion battery that can get 1.5 hours of recording per charge. It can be recharged using the USB port inside the device.
