this remote control system will let you manually trigger your Nikon’s shutter release from a distance of up to 300 feet. There’s also GPS tagging,and a toggle in the app for adjusting exposure length. The app is free, but the dongle will set you back $149. It communicates via Bluetooth, which won’t require line of sight like Nikon’s own IR remotes. Compatibility is set to expand to include Canon DSLRs and Android and BlackBerry smartphones in the future,  you can pre-order your BlueSLR at the source link below.
