PTZ Camera Installation

A pan–tilt–zoom camera (PTZ camera) is a camera that is capable of remote directional and zoom control.

These are similar to the dome cameras, but they have a few more features. Consequently, they are also more expensive because of those features. The rotating head camera looks like a dome, but instead there is a small lens that can be maneuvered around by remote control. Some of them are hooked up to a special system designed only to operate the camera; more advanced models may be able to be accessed by a home computer. Some of the cameras have a feature to allow random rotation. They can be set to rotate at a specific time – or to just randomly rotate. If a vandal approaches a home or business with one of these cameras and has any knowledge of security devices, they will move on, knowing it is not worth the effort. The rotating head camera has all of its wiring securely protected inside the metal casing, which is shaped like a tall dome. At the end of the camera, the small lens head is made of durable material and protected since it is under the surface and recessed into the metal casing. This makes it difficult for the vandal to destroy it. When installed properly, these cameras are also very difficult to knock down, especially if they are well above head level. Most of these designs also have powerful zoom, so a criminal will know they can’t expect to outsmart it. In a continually-rotating head, the criminal will also have something else to think about – whether the head is automatically programmed or the owner is inside, making the camera turn. Either way, they do not want to mess with these types of cameras.

Both styles of vandal-proof cameras are great for business owners and homeowners. The least expensive method is to hook up a dome camera and connected it to a closed circuit channel on the television. This allows the home or business owner to see what is going on outside simply by turning their television set to the right channel. Some sets also have their own TV set, apart from the home television. It is also possible to see a split-frame screen with views from each of the locations if multiple dome cameras are installed. With a rotating-head camera system, the cameras can be hooked up to a closed circuit television or, in some cases, to a computer. Computerized systems are generally more expensive and come with more complex software, so they are better suited for large business owners who have so many cameras that they require quick access to several screens. Homeowners and small business owners will benefit more, as far as cost and efficiency are concerned, to purchase a closed circuit rotating-head system instead. These are much easier to install – most come with a do-it-yourself installation kit and accompanying instructions. Always be sure to buy products from a reputable company. Choose companies that offer warranties and product guarantees. A good company will always stand behind the vandal-proof camera systems they sell.

Auto tracking on PTZ Camera

An innovation to the PTZ camera is a built-in firmware program that monitors the change of pixels generated by the video clip in the camera. When the pixels change due to movement within the camera’s field of view, the camera can actually focus on the pixel variation and move the camera in an attempt to center the pixel fluctuation on the video chip.

This results in the camera following movement. The program allows the camera to estimate the size of the object which is moving and distance of the movement from the camera. With this estimate, the camera can adjust the camera’s optical lens, zooming in and out, in an attempt to stabilize the size of pixel fluctuation as a percentage of total viewing area. Once the movement exits the camera’s field of view, the camera returns to a pre-programmed or “parked” position until it senses pixel variation and the process starts over again.
