The DVF-500 from Digital Ally has a complete digital video system integrated into a water- and shock-resistant, machined aluminum flashlight. This tough flashlight features unbreakable LED lights and records onto solid state memory, which is not affected by temperature, vibration, or impacts and will retain your data even if the battery goes dead. Audio/video may be recorded with or without the lights active. The wide-angle lens allows recording without careful aiming and pre-event recording allows up to 60 seconds before pressing the record button to also be recorded. The rechargeable LiIon battery pack lasts up to 16 hours and the memory will hold up to eight hours of footage.
