Last week I was having a conversation with a client who needed some kind of smart camera to be installed in his home. I mentioned that I was working on a construction project with a type of camera that is known as PTZ security camera that is also used for home use and business use. But there came many questions:
- What does PTZ mean?
- How does a PTZ camera work?
- How much is a PTZ camera worth?
- Pros and cons of a PTZ Camera.
In this article we will answer these questions.
What does PTZ mean?
In the commercial environment there is no explanation of what PTZ means, but in reality it is an acronym that is composed of three basic English words:
Panning: Swing (a video or film camera) in a horizontal or vertical plane, typically to give a panoramic effect or follow a subject. Source.
Tilt: Move (a camera) in a vertical plane. Source.
Zoom: change smoothly from a long shot to a close-up or vice versa. Source.
How does a PTZ camera work?
In order not to make the explanation long, the difference with a regular camera is that we will have a joystick either physical or virtual (apps) to control the focus area of our camera. The new technologies allow the camera to adjust the focus of our objective. But we can also do it in a manual way just like the iris opening. Depending on the model of our PTZ, we can make use of the preset adjustments. We can take advantage of performing a repetitive routine without major complications. Other more advanced models come with the auto tracking function, which is nothing more than the tracking of a moving object that enters the camera’s focus area.
How much is a PTZ camera worth?
Technology is advancing very fast, it has advantages but also disadvantages. One of the disadvantages in the price. It will not be the exception with security cameras especially PTZ. Within the world of security cameras, we have many options that also depend on the technology that is being used, for example the resolution of the video, which can be SD, HD, 4K, etc. Another important factor is its video transmission technology, we talk about COAXIAL or CAT6. The price range is from should be from $300.00 to $3,000.00
Those are some models of PTZ Cameras:
