What is Frame Rate?
A frame rate, expressed as fps or frames per second, is the number of frames (or images) you camera can take per second. The current industry standard for clear, smooth video even with moving objects is 30 fps, although the quality of video you’re hoping to capture and your network’s bandwidth heavily influence what frame rate will work best for you. 30 fps is the standard rate for your television, since it results in smooth movement of people and objects between frames.
What is the Difference Between Frame Rates?
Frames per second, or fps, are the simple act of measuring how many video frames the surveillance camera captures per second of video. 30 fps means the camera captured 30 frames in a single second of video; the higher the frames, the smoother the video will be.
Lower frame rates can result in choppy or broken movement, but is less intensive for the camera and your network, ideal for locations without fast moving objects. If you are recording something fast like traffic, however, 30 fps would be necessary to smoothly record movement.
Frame rate also has an impact on the size of your video files. A higher frame rate of 60 fps results in more frames, so the video file will be larger. If your system has a large storage capacity and bandwidth, and you need to record extremely clear video with fast motion, increasing your frame rate may be an option.
If your storage or bandwidth is limited, a lower bandwidth of 15 fps will create smaller videos and prevent undue stress on your network. In many circumstances, a lower frame rate will still record video that is smooth while saving you space and bandwidth.
How Managing Frame Rate Can Help You
When it comes to managing your camera’s frame rate settings, there are many options to consider, including:
- Is your bandwidth limited? Videos with lower frame rates, say 15 fps, are smaller so they are less intensive to upload and view in real time
- Can you set up multiple video streams? If so, you can set remote viewing streams to lower frame rates while local viewing can stream the video with a higher frame rate
- Will you use motion detection? You can set the camera to record video with a low frame rate to reduce the impact on network bandwidth, and only use higher frame rates when motion is detected and clear video is necessary
Most surveillance cameras and systems allow you to customize the frames per second settings, but be aware that most cameras have a maximum setting of 30 fps. Check out our leading IP video surveillance manufactures for the best products and prices, including Optica and Axis.
