There are many different types of cameras to suit any location. From inside a wall clock to the roof of a building, there really aren’t many places you can’t hide a camera. Here is a list of camera options that are available



Features
Every scene has its own particularities that call for various features from cameras. The following is a description of some crucial features that can mean a world of difference in almost any situation.
Network cameras are analogue or digital video cameras, plus an embedded video server having an IP address, capable of streaming the video (and sometimes, even audio). This means the cameras can be attached to existing computer networks, saving costly cable runs.

Due to the fact that network cameras are embedded devices, and do not need to output an analogue signal, resolutions higher than CCTV analogue cameras are possible. A typical analogue CCTV camera has a PAL (768×576 pixels) or NTSC (720×480 pixels),whereas network cameras may have VGA (640×480 pixels), SVGA (800×600 pixels) or quad-VGA (1280×960 pixels, also referred to as ‘megapixel’) resolutions. There are even some ultra-high resolution CCTV cameras, like Arecont Vision’s 8-Megapixel monster.

Auto iris lenses are used to maintain proper light levels. These are lenses with an electronically controlled iris. This allows the lens to maintain one light level throughout varying light conditions, like flipping on a light switch or the change from night to day.

In certain applications an auto-iris lens is insufficient for the level of light available. In such cases a different type of camera is required; a low-lux camera for instance. These cameras have a lux specification to distinguish the sensitivity between cameras. The lower the number the more sensitive the camera is to light. A camera listed as having a lux sensitivity of 0 would be able to see in complete darkness (ie: infrared camera – see below).

Infrared cameras are 0-lux cameras that allow a pitch-black scene to be visible by capturing the infrared light emitted by their equipped LED infrared illuminators. The more illuminators there are, the more light an infrared camera will have to produce its image.
