Internet protocol or IP surveillance cameras (commonly known as IP cameras) are digital video cameras that are used for the purpose of inspection, while sending and receiving information via a preferred network over the Internet. These cameras can be set up and used in neighborhoods, small enterprises and corporate headquarters. There are many types of IP surveillance cameras including fixed IP dome cameras, pan-tilt-zoom (PTZ) IP cameras, PTZ dome IP cameras, Megapixel IP cameras and many others. Here we will discuss about the pros and cons of PTZ IP cameras.
Pan-tilt-zoom (PTZ) cameras have the ability to capture videos and images at various different angles while investigating a wide area of the premise. These cameras are the best choice for parking areas, garages, warehouses, roof tops and construction sites. Given below are a few pros and cons of the PTZ IP cameras:
- A PTZ IP camera has the ability to pan, tilt or zoom using manual or auto controls, and covers large areas (hundreds of acres) of land. This cannot be possible with a fixed camera which only covers a small area.
- PTZ IP cameras are used normally indoors with an operator that can control the cameras in order to keep track of any suspicious activity or respond to a particular incident. The operator can easily capture and zoom into the details of the intruder such as his facial features or license plate. The suspect can also be followed across a large area by the operator.
- The cost of coverage of a given area can be reduced as the PTZ IP cameras cover a large area. These IP cameras are more pocket-friendly as compared to the traditional closed-circuit security systems because no huge infrastructure is needed for their installation and use.
- PTZ IP cameras are complicated mechanical devices so they tend to have service issues. They also have shorter life spans as compared to fixed IP cameras.
- Usually the operators place or leave the PTZ IP cameras in different positions. Although this can be solved by using some kind of ‘home’ functionality, many PTZ IP cameras are not configured accordingly.
- Some of the PTZ IP cameras work poorly over IP networks. Network viewing often needs on-screen PTZ camera controls which are difficult to use for the operator. This is a common problem with IP networks.
Thus, in general, there are both pros and cons of using a PTZ IP camera. PTZ cameras are great for viewing large areas. The best thing about these cameras is they can be put in an auto-patrol mode in which they can set automatically to fixed positions. If the camera detects any movement, the optional IP network video recorder software can be set to record and capture the video until the movement is stopped.
