The world's first wearable high definition camera for dogs

PetNow is the world's first wearable high-definition camera for dogs giving owners the opportunity to capture a first-person perspective of their dog's life and activities when pets are home alone.

PetNow consists of three parts: a "soft, lightweight, breathable" harness, a WiFi-connected HD video camera that quick-mounts onto that harness, and an iOS/Android app. Utilizing the app, users can view the camera's live-streamed 1080p/30fps video at any time, wherever there's internet access.

Users also can talk to their pet via a two-way audio system. Additionally, if the animal wanders into an unlit part of the house at night, the camera's night vision system will still show what's going on.

PetNow is made to allow free movement for pets and is available in five sizes to fit a dog of any size. For convenience, it has an on-board battery and low power consumption that keeps it running for up to three months.
