Hi all,

After being knocked off my bike last year, I've decided to invest in a decent quality helmet camera for my commute. The criteria is as follows:

• must be weatherproof
• must be light and compact so that it doesn't weigh too heavily if mounted on one side of my cycling helmet
• must have a user-replaceable battery (or at a push, at least have an option to replace the battery at reasonable cost/turnaround)
• must be able to connect to it using a smartphone in order to change settings and/or preview what the camera is seeing
• must be able to do 60 frames-per-second HD
• must be able to record usable footage after dark (in street lighting)

So far I've looked at the following:

Drift Ghost HD
Drift Stealth
Garmin VIRB Elite

Any other recommendations from helmet cam users? I'd like to know what your experience with your helmet cam is like, as it's possible that some of the criteria above may be less important.

Thanks in advance.
