If you have a need to see in complete darkness but do not want to carry around night vision goggles everywhere with you, a better option might be a new iPhone 6 case from MSM Labs.
NVC transforms your iPhone 6 or 6 Plus into a super-spy gadget enabling high definition pictures and video to be captured in complete darkness. The camera uses special Infrared LEDs for vision in complete darkness and provides a range of thirty feet or can be turned off for passive viewing using ambient light. The case itself is a complete capture system meaning that while it is designed to be a case, it can also be placed as a camera to be remotely monitored through a free app. In addition to the five-megapixel camera, it has a built in Micro-SD card slot for storing anything you want to capture, is Wi-Fi enabled and contains a battery that can also be used to charge an iPhone.
NVC charges though a standard five-volt Micro USB connection in about three hours and can provide night vision for almost four hours on a full charge. MSM Labs will offer the NVC in early 2015 with a retail price tag around 250 bucks or you can grab one for a discount by backing their Kickstarter.
