(Iris is the slit or the eye hole in the camera through which the camera focuses on the object to be captured).
This type of iris is found in analog cameras where the focus on the camera is set manually. The camera is kept in a steady position focused on one particular spot. You have to manually turn the camera if you want to change its point of focus. If there is a particular point or area to be covered by the camera then a manual iris is preferred. For example in a godown or a stairway, a manual iris camera can be focused on the most vulnerable spot where thefts can occur.
Auto Iris changes focus automatically following the movement of the camera. Cameras with auto iris can be used when you have to cover a wide area. The camera can be set up to pan from left to right or tilt top to bottom. This type of camera finds use in most applications.
A wide range of CCTV surveillance cameras suitable for indoor and outdoor home security applications are available in the market now, such as to monitor entrances and exits and to keep an eye on the children and domestic staff when you are at work or away on holiday.
Indoor Cameras are placed inside the home. These are black and white cameras with not very high resolution, and ability to work in low light conditions. These are the features of an Indoor Camera.
As the name suggests, these cameras are placed outdoors, in grounds, housing societies, outside shops and malls, on roads and outside your home or office entrance. Typically, these cameras cover larger areas.
High Resolution Cameras
Low Light Cameras
Cameras with infrared (IR) LEDs can be used at night, when light is less or absent. They can capture accurate black and white image with the IR LEDs that surround the camera, and emit a light captured only by the image sensor. The number of LEDs range from 25 to 70 LEDs.
The various types of cameras based on size and shape are Box Camera, Dome Camera, Bullet Camera, Board Camera and Hidden Camera. The functions of all these cameras are the same, only their construction is different. Bullet, board or hidden cameras are used for outdoor purposes because they have auto iris and high resolution. For indoor cameras it is mostly a bullet or dome camera which does not need housing. This is because the cameras are not vulnerable to weather conditions and there is no scope for moisture to enter into the camera.
