HIKVISION PTZ CCTV
HIKVISION PTZ CCTV DS-2AE5225TI-A IR Turbo 5-Inch Speed Dome is able to capture high quality images in poor light environment. The black anti-reflective glass increases the luminousness which helps IR distance reach up to 150 m. The embedded CMOS chip makes WDR, and real-time 1920 × 1080 resolution possible. With the help of the 25× optical zoom, and IR cut filter, the camera offers more details over an expansive area.
A PTZ camera is a camera with pan, tilt, and zoom functionality. These movements can be manually controlled by using monitoring software or a joy stick, or automatically set up using camera management software. Being able to move the camera necessary by a security guard allows your security staff to respond quickly to events they spot with the surveillance system.

You can also use camera management software to set up guard tours, where the camera will automatically move to monitor pre-set locations on a schedule. Some cameras can also auto track movement, following a person or car moving in its field of view.
How PTZ Can Help You
If you’re monitoring large areas such as parking common areas in school and business campuses, or convention centres, a PTZ camera allows you to both monitor the overall area and focus on suspicious activity. This gives you a more flexible and functional surveillance system, especially when combined with fixed network cameras that track room entrances and exits but cannot monitor the area at large. This allows the PTZ camera to move around as needed while the fixed cameras ensure important locations are always monitored.
PTZ cameras come in a wide range of styles, making them easy to fit into your surveillance system, although the most common form factor is a dome. The cameras are also available in indoor and outdoor models, so you can install a camera in any location.
