You might want to shoot pictures to capture memorable moments or to catch people redhanded doing what they should not be doing. The latter seems to happen more often than one would like. This is where an electrical box camera comes in handy. Unlike most hidden cameras it is weatherproof and can send both color and black and white images. This is one of the few spy cameras that can be used in an outdoor application as it is a wireless camera and runs on an eight-hour rechargeable battery pack. It has a.003 lux, which allows images to be seen in almost complete darkness with some ambient light required like a street light or a spotlight. Attach a DVR to it and record images at will.
You can take an everyday household object that people are used to seeing and put a micro board camera inside it. Most of these objects are working objects to keep the deception at a high level. Board cameras can be perfectly used for customized secret application. One of the best models is the spy clock DVR with motion detection which is a real working clock. You can record up to 90 minutes of video on a 4 GB micro SD card. It can support a much bigger SD card and a rechargeable battery. Wireless security cameras are very convenient to use as they can be placed at any location without any hassle of wires.
On the other hand, the optical zoom cameras are largely used by corporations or very important government buildings where security is a priority issue. Distance that a security camera will cover varies for different models. Most PTZ cameras can easily reproduce a vehicle's license plate from as far away as 1000 feet. Many large discount or department stores use these cameras to watch for inventory shrinkage, reducing losses by more than what it costs to purchase and operate these machines. Having the ability to pan a camera to the left and right, up or down and zooming at long distances makes for a complete view in any zone of security.
Allied to these is the PTZ control joystick with which you can manipulate the angle and shoot from just about any location, especially if it is not an auto track model. You do not have to worry about low light areas because the PTZ camera has a low lux setting which enables the camera to capture and display clear images located at low lighted areas. However, any kind of security camera installed outdoors should have vandal proof outdoor camera housing. Typically cameras can be only vandal resistant rather than 100% vandal proof. It is more sensible to place them where a vandal can't get at them with a hammer or a can of paint.
