Panasonic has unveiled a wearable 4K camcorder that includes NFC pairing, enabling consumers to link the device to their smartphone or tablet and then broadcast live videos via Ustream.

The dustproof and waterproof HX-A500 comes in two parts connected by a cable — a main operating unit that weighs 119g and a camera section that weights 31g and can be mounted in a detachable armband, placed in a head mount or on a belt. Available from May, the A500 will be priced at £379.99 (US$628).
