Mini Spy Hidden Camera device head is really small compared to some spy cameras in the market. The images are clear however, it also has some delay. Depending on how strong and close is your wifi, there are about 3-4 seconds of delay. So if someone is moving fast all you can see is he/she is in one spot and instead jump to another. The largest par with this camera is the battery. PLEASE design your battery smaller, PLEASE! Your littery have to hide your battery somewhere dry and not easy to catch fire. Serially, they really need some improvement on the battery. Otherwise, the camera works just fine.
