The Datavideo BH-05 is a ball head mounting solution for accessory mounting on camcorders. The camcorder should have a typical shoe mounting point while the accessory should have a 1/4-20 mounting point. The ball head will lock the accessory securely in place at the precise angle required for optimum use. This type of mounting bracket is commonly used for mounting a small LCD monitor on top a camcorder. Other accessories like small lights or a wireless audio receiver is also typically attached in this manner.
