Advantages of PTZ Security Cameras for Video Surveillance
A PTZ (Pan, Tilt, and Zoom) security camera differs from fixed surveillance systems because it can move up and down or left and right for 360º viewing. Because of high-speed pan and tilt rotation abilities, PTZ security cameras can provide detailed and multiple imaging of an area or object for better surveillance. They also have zoom in and out features, which are ideal for viewing details from afar. The popularity of PTZ cameras are because of the following features:
Built-in Motion Tracking
PTZ Cameras have built-in motion tracking capabilities because of which they can automatically pan, tilt or zoom in/out while recording video or capturing images of a suspicious person or activity. They can scan specific location or incident area automatically without any human control.
Four Alarm Inputs
PTZ cameras can support four alarm inputs at a time including motion detectors, door contacts, glass break devices, etc. Users can program their PTZ camera, which is attached to any alarm input, to stop any activity that can cause potential problems. You can even program these cameras to focus on different areas at preset intervals.
Auto Focus Ability
PTZ cameras come equipped with powerful zoom lenses. These lenses can auto focus on an object or person to provide detailed and clearer image.
Powerful Zooming Feature
PTZ cameras use optical zooming, which means you can zoom in any image and quality will not be affected. The lowest zoom ratio for PTZ cameras is 10x optical, and the highest is 36x zoom ratio lenses. Powerful zooming feature of PTZ cameras make them a good surveillance system for large areas such as parking lots.
Remote Control Option
These cameras use motors for aiming and zooming features. The actual orientation and optical zoom of PTZ cameras can be controlled remotely. Communication signals can be sent via cables or wireless network. In fact, a single user can control multiple PTZ cameras using a digital controlling device.
PTZ security cameras also come in weatherproof and day/night configurations. A PTZ camera can provide color videos/images during day time and black & white at night because of its day/night capability. These cameras are also tamper and weather resistant. They are built using rigid metal housing and poly-carbonate domes. You can find high definition options in PTZ cameras that will deliver resolutions from 720i to 1080P. Since PTZ security cameras are expensive, so install them in areas that require detailed monitoring.
