I am Himadri. I want help you.
Please open below the link for buying wearable video camera ..
Thanks for your answer. I saw they have wifi feature so I can use my phone to control it. But they didn't mention how and what kind of restrictions there are. I contacted them but no response. Can you get the those for me? Otherwise it will be of no use to get something like that and found out I have to buy a specific phone.
