Security cameras are used essentially to prevent crime and other wrong doing. The idea behind using an mini ir spy camera is to see what people are doing even in the dark. It could be used to check out on intruders and thieves or even employees at a commercial outlet. If you intend to use it indoors, you could look for the kind of spy camera that looks like a wall light switch. It uses a rechargeable battery that will last up to five days in standby mode. All video is recorded using motion activated recording with a date and time stamp for easy retrieval. It comes with 4 GB SD card but will support up to a 32 GB card for more data storage. Nobody will even dream that they are under surveillance!

Some of the more common spy cameras under $100 are a ball point pen with six different models, a wristwatch, a calculator and a BIC lighter. There are also two overhead smoke detectors with board cameras inside them with which you can see what your employees are up to, especially near the cash register. One unique spy camera is the hat spy camera with built-in DVR. This is a hands-free mobile model. It looks like a regular baseball cap but has a DVR inside. It uses a 4 GB SD card to record video. The USB cable allows you to download to your computer easily.

On the other hand, the bullet mini security camera looks like a bullet or a lipstick and can easily be concealed because they tend to be small and cylindrical, usually three to four inches in length. One of the best bullet cameras you can get is the high resolution home security camera. With 56 infra red LEDs you can see up to 150 feet away at night. Most lipstick style cameras are weatherproof and can be used for both indoor and outdoor applications. Their small size ensures that they are ideal when discreet or covert surveillance is needed. Their compact design means they usually have smaller non-adjustable lenses which limit the cameras to wider angle shots.
