Do i need Wi-Fi? Yes, I'm lazy to pull SD memory card. I use my iPhone 5 or iPad had no SD memory card (some Android phones have SD memory card). It's works with Wi-Fi from camera to phone (Live stream and download few video files in short storage in phone) for easy quick report police on any public street. also, pull SD memory card for at home. It can transfer to my computer/laptop for extra storage and then, delete whole SD memory card to return camera.
No Wi-fi mean save your budget, You can use Android phones with build in SD slot or laptop. those SD memory card is only 16GB (32GB option) in camera is not enough storage as i wish to upgrade 500GB SD memory card in camera .
