What is PTZ camera? Definition & Meaning by Eocortex (2024)

FAQs

What is best definition of PTZ camera? ›

What are PTZ and ePTZ Cameras? Pan-tilt-zoom (PTZ) cameras are built with mechanical parts that allow them to swivel left to right, tilt up and down, and zoom in and out of a scene.

They are commonly referred to as robes, an abbreviation for robotic cameras. These systems can be remotely controlled by automated systems. PTZ cameras are in high demand as a solution because of the diverse range of applications that they can support. Some examples of these applications are provided below.

Limitations of PTZ Cameras

Because PTZ cameras cannot record areas they're not looking at. If the camera is panned to the right and an incident is taking place to the left of the camera, the action may not be caught. In other words, intruders may be out of the camera's field of view when it matters most.

The difference between PT and PTZ

On the other hand, PTZ Cameras offer more advanced and comprehensive features, making them ideal for enterprises and public organizations with larger-scale or more demanding security requirements.

How long do PTZ cameras last? Due to their weather-resistant properties, a PTZ camera can last up to 10 years with regular maintenance and cleaning when required.

PTZ cameras are versatile surveillance cameras that allow operators to remotely control various functions such as pan, tilt, and zoom. They can rotate horizontally (pan), vertically (tilt), and adjust the magnification of the image (zoom) as required to provide a comprehensive view of the surveillance area.

PTZ cameras can be controlled in a variety of ways including an IR remote, a joystick controller, and software. IR remote controls usually offer a limited set of basic features for controlling the camera and recalling presets.

Sony PTZ Cameras: Sony offers several professional-grade PTZ cameras with high-quality video, powerful zoom, and reliable performance.

However, on average, a PTZ camera can have a range of up to 300 feet (91 meters) for clear identification and up to 1000 feet (305 meters) for detection purposes. Some high-end PTZ cameras can have a range of up to 5000 feet (1524 meters) with advanced zoom and lens technology.

Where should a PTZ camera be mounted? PTZ cameras should be mounted on a wall or ceiling at a height of 5ft or more. From that location, it should be able to cover a wider area without leaving any blind spots.

Do PTZ cameras move on their own? ›

PTZ cameras receive data via RS-422, RS-485, and modulated into the blanking spectrum of a video signal over twisted pair, coaxial cable, or optical fiber. Sometimes a PTZ camera will spin, drift, or "move on its own." PTZ camera reboots Consistently. PTZ camera control is: intermittant, lossy, or erratic.

Since the PTZ has 25x optical zoom, the higher up the better. The indicated positions (1 to 5) are approximately 12 meters (approximately 39 feet) from street level.

PTZ stands for Pan, Tilt, and Zoom. Where Pan means to rotate, Tilt to move the lens up and down and Zoom to zoom in or out on a part of the image you're trying to capture.

1- They require a power supply and a cable to supply this power to the dome. Often, external domes are 24V A.C but some PTZ domes are 12V. 2- They require a cable to get the video signal back to the monitor or recording device.

Here's the viewing angle information of this PTZ: Resolution – 4MP / 2688*1520@30fps. Lens – 4.8-120mm Varifocal Lens. Angle of View (H) – 55.5 ~ 3.1° / Angle of View (V) – 32.9 ~ 1.7°

PTZ cameras are pan, tilt and zoom robotic video cameras that allow an operator to control the camera remotely. PTZ cameras can pan horizontally, tilt vertically and zoom in on a subject to enhance the image quality without digital pixelation.

PTZ cameras offer panoramic views and precise zooming, unlike fixed cameras. Ideal for security, PTZs can remotely track intruders and deter crime. Advanced features like auto-tracking and presets enhance usability.

ePTZ is an abbreviation for “electronic pan-tilt-zoom” but is also referred to as digital PTZ or virtual PTZ. Unlike a PTZ camera with motors that physically move the unit, an ePTZ camera does not move. It simply takes the image within the camera frame and moves within said image.
