Do You Know About IP PTZ Cameras? What Is an IP PTZ Camera?

Understanding IP PTZ Camera

IP PTZ cameras are a type of network video camera that feature PTZ functionality (pan, tilt, and zoom). Due to their high rotation speeds that can reach up to 400°/second, they have been given the name "high-speed dome". The abbreviation PTZ stands for pan, tilt, and zoom, respectively. These cameras use network connections and transmit video signals over the internet, which means they can be accessed remotely. IP PTZ cameras are usually equipped with high-resolution sensors to provide clearer images and videos.

This type of camera has many different applications, such as video surveillance and security monitoring. Due to their flexibility and customizability, they are widely used in various settings, including residential, commercial, and public places.

Note that IP PTZ cameras usually require additional power and network interfaces to work properly and transmit video. Additionally, due to their complex functionality and configuration, using and maintaining IP PTZ cameras may require more technical knowledge.

Uses of IP PTZ Camera

IP PTZ monitoring cameras are used to monitor large areas that require a full range of static cameras. In addition, these cameras can be used in conjunction with zoom lenses that have a high optical zoom ratio of up to 40 times. These PTZ domes are controlled using an external keyboard or a mouse on a PC through video management solutions. Cameras with applications can also easily rotate, tilt, and zoom on smartphones.

So far, most IP PTZ cameras have built-in infrared LEDs with ranges of up to 300 meters. Their advantage is that they do not require external IR LED spotlights, and the IR spotlight illuminates the exact location where the PTZ dome is looking. A big disadvantage is insects in the summer months, as they are attracted to the infrared light (with a frequency of about 850nm, light, and slightly red light). Visibility may be affected because the infrared LEDs are mounted close to the lens, and night shots may not be available. Therefore, if a good effect is desired during summer nights and if video analysis is used, it may be necessary to use a separate IR LED spotlight.

Many IP PTZ cameras offer what is known as touring or "patrolling," where the dome departs from a certain preset position at a specified time period. During the setup, a preset, or dome view, is input. These preset positions are now automatically lowered by the dome, stay for a while, and then move to the next position. The presets are also associated with zoom factors, so each position is assigned a zoom setting.

Of course, a disadvantage of this process is that all directions cannot be observed simultaneously. There are several static cameras that can monitor each section of the area, but there are also interesting solutions that combine static cameras with rotatable systems.
