[1] A Camera is: "A residence used during short visits by an official and attendants of the Knights Hospitallers for administrative purposes on their estates.

[3] During the reign of King Henry II (1154-1189), Robert de Bakepuze donated the church and some land at Barrow upon Trent to the Knights Hospitaller of Yeaveley Preceptory, also in Derbyshire.

[5] By 1338 the camera is recorded as having a bailiff and an income of £30; Page, however, believed that it was "doubtful if regular brethren of the order were ever resident here".

[5] The Preceptory and Camera were suppressed during the Dissolution of the Monasteries; its property and lands were confiscated in 1543 and granted by Henry VIII to Charles Blount, 5th Baron Mountjoy.

[4] Following the Dissolution were incorporated into Arlestone House Farmhouse which was constructed in the 16th–17th century, and is currently Grade II Listed.
