Battery Capacity The built-in Li-Poly battery will record for around 90 minutes. Using the hard wiring kit negates the need for the battery by using the external power source. Alternatively, the optional RoadHawk Waterproof USB battery pack supply can be connected for longer record times (up to 4.5 hours). Both of these alternatives ensure the camera remains waterproof. Rf remote control - when not using the hard wiring kit the additional rf remote control allows greater flexibility when using the roadhawk bullet r+ moto edition. This not only allows remote recording but also the ability to take photographs. The software also allows loop record mode to be turned off for the rides you dont want recorded over, the time and date stamp added removed or changed, and footage inverted for times when mounting the camera. Memory capacity the bullet r+ moto edition is supplied with an 8gb microSD memory card that can hold around 90 minutes of 1080p HD video. When upgraded to a 32gb card, the recording capacity is extended to over 5 hours (subject to power supply). The additional rf remote control allows for greater flexibility when using the roadhawk bullet r+ moto edition, not only allowing remote recording, but also the ability to take photographs.
