10 Not-So-Obvious Benefits of PTZ CCTV CamerasFebruary 26, 2010 in Business Security, Security Cameras
1. Autonomous Patrol & Tracking
PTZ cameras can be set to tour areas that you specify, and can actually track the movements of suspicious people or vehicles when optional video analytic devices are used.
2. Multiple Alarm Inputs
PTZ cameras typically have four alarm inputs. Devices such as motion detectors, glass break devices, door contacts, etc. can be placed in critical areas and connected to PTZs. When activity occurs in those hot spots, the PTZ can be programmed to stop all other activity and zero in on potential problems.
3. Low Light Capability
During hours of darkness, PTZs equipped with a day/night feature will switch to a super sensitive mode – which allows the camera to gather details in the lowest of light. PTZ cameras with a day/night feature will typically accept infrared illumination and some are even available with IR on-board.
Many of today’s PTZ cameras are not much larger than fixed dome style cameras. Those that are a little larger can be installed in ways that only a small portion of the profile is visible.
5. Vandal Resistant
PTZ cameras are usually mounted high above the ground for the best view possible – which affords them a certain level of protection. Additionally, most PTZ cameras are constructed with tough metal housings and use high-tech poly-carbonate domes that are virtually shatterproof to vandals, while providing crystal clear images.
Today’s PTZ cameras are built to withstand years of direct exposure to the elements. In fact, many of our customers looking to mount reliable cameras in hard to service locations (e.g. the side of sky scrapers) put their trust in high quality PTZ cameras.
7. Powerful Zoom
Even the smallest PTZ cameras with the lowest of zoom ratios are light years ahead of traditional fixed cameras. A common low zoom ratio for PTZ cameras is 10x optical, and many are available with powerful 36x zoom ratio lenses. Additionally, it is standard for these high resolution cameras to offer a digital zoom feature, providing even greater magnification.
8. Fast Pan/tilt
PTZs are often referred to as “speed domes” for a reason – they are lighting fast. It’s typical for PTZs to pan/tilt in a completely different direction in less than a second. Despite the speed, they are easy to control and can move with precision even when focused on far away objects.
9. Auto Focus
One feature often overlooked but vital to the PTZ camera’s ease of use is its ability to auto-focus. Cameras on board will auto-sense the right object or area to bring into focus, and easily keeps up with the rapid speed of the pan/tilt motors.
10. Flexible Remote Control Options
Remote controlled cameras have been around for decades, but older arrangements sent power to each motor limiting where and how the camera was manipulated. Digital communication between a controlling device and PTZ camera provides users with complete control, and is available for both digital and analog style PTZs. Communication between controlling devices can be sent via cable, via wireless means or over the internet. And because the communication is digital, multiple cameras can be controlled by a single controller.
