KDN Technologies is the developer of the Hyakume IP Camera Viewer app for Android, available on the Google Play Store and Amazon Appstore.
Watch & Record IP Camera Video Streams; Access Your Cameras Remotely

In Japanese folklore, the Hyakume (百目, "hundred eyes") is a yōkai ("strange apparition") whose man-sized body is covered by a multitude of large, unblinking eyes. It usually shelters overnight in abandoned temples, protecting them from would-be thieves & vandals.

Use the Hyakume app to easily view & record the H.264 & MJPEG video streams produced by a wide range of IP cameras (security, surveillance, doorbell, webcams, traffic, weather, repurposed smartphones, etc.).

Hyakume can store up to one hundred Camera entries in 10 Camera Lists (10 Cameras per List). Create separate Camera Lists for your various IP camera locations (home, business, storage, etc.).

To add a Camera entry, give it a unique name & provide the target IP camera's IPv4 address, video stream path, format & port number.

Tap a Camera entry to view it.

While viewing, you can record video, capture snapshot images, & expand the view to full-screen.

Hyakume can be run in dedicated Relay Server mode, which provides free on-demand remote viewing of local IP cameras (spare Android device required).
