What is PTZ Camera?

PTZ (pan, tilt, and zoom) camera has mechanical devices that enable them to swivel left to right, tilt up and down, and zoom in and out of a scene. The pan-tilt mechanism controls the horizontal and vertical movement of the camera system. The performance is defined by the speed of motion and accuracy. The greater the accuracy required, the further away you want to view an area. 

Pan-tilt drive mechanisms are classified into two different types. One type features gears, which is more exact, and another one is using belts. Position sensors may also be a part of the pan-tilt mechanism to guarantee that it moves to the precise area needed. It can be positioned with a precision of 0.01 degrees with the correct control system.

You may remotely operate the PTZ camera system using an app on your smartphone or software on your computer. Outdoor PTZ camera is frequently used to monitor wide open area that demands for 180- or 360-degree vision since it enables you to keep an eye on a significant portion of the area. They can also be configured to automatically track motion-triggered activities or follow a predetermined schedule, depending on the camera or software. PTZ cameras are typically used in conjunction with a larger surveillance system, tracking movement while a stationary camera takes in-depth pictures.

How many types of PTZ Cameras?

PTZ IP Camera: WiFi or Power over Ethernet can be used to deploy PTZ internet protocol (IP) cameras (POE). Compared to normal analog PTZ cameras: without a wired connection, WiFi PTZ cameras connect wirelessly to a router. (However, a power source is still needed.) It's also advised having a powerful WiFi connection to avoid slowness or poor video quality.

PTZ POE Camera: A POE camera receives power and an internet connection via an Ethernet cable connected to a POE switch. It typically has a stronger connection range than WiFi.

PTZ Analog Camera: Analog (CCTV) PTZ cameras are connected to digital video recorders (DVRs) through coaxial cables and record surveillance video by using an analog video signal. In most cases, analog PTZ security cameras can't send video data on their own but need a DVR to allow encoding, compressing, and saving of the video.

Outdoor PTZ Camera: Outdoor PTZ camera needs to be capable of handling more severe weather and temperatures. They are normally protected from the outdoors by a waterproof shell with an IP rating.

Wireless PTZ Camera: Wireless PTZ camera is able to transmit video wirelessly in situations where the installer is unable to run video cables. Although transmitter sets can be used to convert analog signals, this is typically done through WiFi. Most of the time, a wireless PTZ camera is used for long-distance outdoor monitoring where running the cabling is hard or expensive.
