Fisheye vs. Pan-Tilt Zoom (PTZ) Cameras
Filed under: CCTV Articles, Comparisons, GeoVision, IP Cameras, Quick Overview
Since I have been involved with CCTV, I have had countless customers tell me that they need a Pan-Tilt-Zoom (PTZ) camera for their application. While PTZ technology certainly has a place in the industry, we are now finding that in many instances, the user’s goal can not only be achieved, but actually improved upon, by utilizing a fisheye camera instead.
Let’s first look at a few of the disadvantages of PTZ Cameras:
- In order to utilize PTZ technology, an operator is required at the monitoring station to physically aim the camera at the point of interest.
- PTZ cameras only record what is being directly viewed. In other words, if the operator zooms in on a given point within a field of view, all other activity goes unseen, and thereby unrecorded.
- With moving parts comes a greater chance for equipment malfunction.
- Cost. PTZ cameras tend to run at a higher price point than other types of CCTV cameras.
All of these disadvantages can be improved upon by utilizing a single fisheye camera. Let’s again address the four items that are listed above, and discuss why a fisheye camera might make more sense for your application.
Advantages of Fisheye Cameras over PTZ Cameras:
- No operator is required. Fisheye cameras have the ability to capture a 360 degree field of view, and with the functionality of the GeoVision software, the user can go back to the data they need to review, and by simply manipulating the images on the screen, they can isolate areas of interest without having to utilize a person at a monitoring station.
- The fisheye camera records everything it sees in its 360 degree field of view. Again, by simply manipulating the image on the screen, the user can see exactly what he wants to see, either live or on the recorded footage. Regardless of what you may focus in on, nothing is missed, and everything is recorded!
- No Moving Parts! There isn’t a moving lens in the fisheye camera. As with any mechanical equipment, the fewer moving parts that exist provide a lesser likelihood of failure.
- Cost – ApexCCTV has fisheye cameras that begin at $339. This is certainly a modest price given the advanced functionality of this technology; PTZ cameras start at a higher price point for the same specs.
There are several great video and photo examples of the fisheye camera that can be found on the ApexCCTV website, GV-FE110, or you can view the video below. If you have any questions, please feel free to contact a qualified Account Manager @ 800-997-8460 or visit ApexCCTV.com!
