Zorachka Homam 64GB Smart Camera
Homam records and encrypts everything on the built-in chip. Video is always stored in high quality, regardless of the quality of the Wi-Fi. No subscription fees. No privacy issues. No missing moments.
The proprietary video protocol used in the Homam 64GB dramatically decreases the required network bandwidth without loss of quality. A unique network system finds the shortest path between the phone and Homam and connects them directly to the local network. Fast response, very little buffering, and long life of storage achieved by the proprietary video file system.
