This may look like an ordinary wall clock but it's actually a covert hidden camera. It has a unidirectional radio remote control allows you to quckly control the clock without having to actually aim the remote directly at the clock, making it perfect for starting and stopping without overt motion.
It is a great choice whether you're keeping watch on your child's nanny, someone coming in to work on your home, or adding a bit more home security while you're away. You can hang this on the wall or place it on your desk.
