If your property is stolen, the most successful way of identifying it if it is recovered is to have it marked with your information. You can easily achieve this by attaching identification plates to machinery, engraving your property or purchasing commercially available products, such as DataDot.
It is important to also keep a record of your valuables and hard to replace items. Use this Property register (PDF, 90Kb) to record your property and keep it in a safe place. It is also a good idea to send it to your insurance company.
