Customer Support Question:
Do you have some documentation on how you handle megapixel IP camera data? I am considering adding a 1.3 megapixel for license plate capture and wondering how you handle the increase in image size / reduced frame rate.
I currently have a DVR with 4 channels @520tvl being captured. I have 1TB hard drive storage, considering pulling one camera away from the analog inputs and reserving it for the IP camera.
Answer:
We have information available about the exact models of IP Cameras we have testing with on our downloads page here

See the release notes for Airship 4.5.
Airship Server handles the video stream in exactly the same fashion as an analog input; we store it in the same way on the available harddrive volumes and we do not transcode the video stream. All we do is wrap it in a container that allows our Client and other playback software to read the video natively. That container adds an insignificant amount of data to the recorded files.
The best way to find out about storage calculations is to ask the IP Camera maker, and then run your own real-world tests to determine the best balance between video quality and storage costs. Even within the same maker, cameras differ wildly in compression efficiency and abilities.
I hope this helps you choose the best IP Cameras for your applications; don't hesitate to seek us out for more info.
Thank you,
