HOME SECURITY SYSTEMS
Home security systems are basically one of two types: CCTV systems and intruder alert systems.
CCTV, or closed circuit TV systems, consist of cameras, connected by cables to a digital video recorder, a device that automatically records the pictures from the cameras.
An intruder alert system can be any device that sounds an alarm or reacts in some other way when an unwanted intruder tries to enter the home. There are many types of intruder alert systems, from complex burglar alarm systems with sensor connected to doors and windows, motion sensors, and the like, to simple outdoor lights that switch on when someone passes in front of them.
Lets look at each of these systems in more detail.

Lets start with cameras. These are the common types of security cameras:
types of cctv cameras
|
bullet camerasA bullet camera is a camera that is fixed at a particular angle and only covers one view. It gets its name from its shape, which is usually a cylinder mounted on a bracket. It was the first type of security camera that came on the market, and its use is now decreasing. It is usually wall mounted.

dome camerasA dome camera is a camera that is concealed inside a plastic dome and is mounted on the ceiling. One advantage of this camera is that its direction is not always evident, so thieves cannot tell whether they are in the picture or not without staring at the camera and giving themselves away.

IP camerasAn IP or Internet Protocol camera, is one that can be connected directly to an internet cable. Anyone who has the IP address and the password can view the pictures from the camera from anywhere in the world. These cameras do not need a separate power connection and can transmit the images over long distances, which make them one of the best solutions on the market.

|
infrared or night vision camerasThese cameras give you the ability to see in pitch black conditions. They pick up the body heat of living things (or other hot objects like car engines) and are excellent for outdoor areas that are not lit, or even main corridors in office buildings that are not lit at night.

PTZ cameras - pan tilt zoom camerasThese cameras allow an operator in the control room to pan (move left or right), tilt (move up or down), or zoom in or out the image, which is a great bonus. Some of them can move back and forth automatically when there is no operator controlling them.
