There are plenty of smartphone apps that let you share live video from your phone’s camera with the world. Knocking Live Video takes another approach, and lets you share it with one person at a time.
Here’s how it works: You download the Knocking Live Video app from the iTunes App Store or Android Market, register for an account, and then search for your friends by username. You can add contacts to friends or family groups to make it easier to find them later.
When you want to share live video, you just tap on your friends’ username from your contact list and they’ll receive a notification letting them know you want to share a video feed. The app also makes a knocking sound like someone knocking on the door — thus the name.
I tested it out by streaming some live video of my cat from my Nexus One to my iPod touch. The image quality was decent, but there was a bit of lag and the frame rates were pretty low. As you can see from the demo video below, wasn’t the only one to experience a bit of lag, but if you’re looking for a way to show the grandparents their new baby, share a bit of a live concert, or ask for help in the grocery store aisle, Knocking Live Video is a step up from snapping a photo and emailing it.
Knocking Live Video is available as a free download from the iTunes App Store and Android Market.
