Maximum length of video

I have an iPhone 5, and was wondering how long of uninterupted video the device will record. I know it is based on the free space available, but some "non-traditional" video recording devices (like my DSLR) will record only up to 10 minutes, before shutting off automatically, and I didn't know if the iPhone 5 opperates that way.

I've tried researching in the communities, and tried finding the info on the technical page, but I haven't found the info yet.

Thanks in advance for any info.
