SmartWater Registration
Read full descriptionHide full description
A quick and convenient solution for registering SmartWater packs as part of a police scheme. To register a pack, simply open the App, login, scan the bottle of SmartWater forensic liquid and input the recipient’s details where prompted. Once complete, the details will be uploaded directly and securely to SmartWater’s database – you need do nothing else. No filling out, storing and posting onerous paper forms. Why does each pack need to be registered? Each bottle of SmartWater® contains a unique forensic code and is applied to the recipient's valuables. If these same items are then stolen and subsequently recovered by the police, SmartWater will use the unique code to link them back to their rightful owner. However, we can only do this if the unique forensic code is ‘registered’ against the pack recipient’s address and contact details on our ISO27001 accredited database. Please note that if you have not been provided with login credentials already, you will need to create these by visiting the SmartWater Police Hub and registering an account.

The California District Attorney Investigators' Association (CDAIA) app allows members to stay connected with their organization anytime, anywhere. The app provides important information and services, including upcoming events, access to training courses, employment opportunities, legal updates, connections to CDAIA’s website, Rap Sheet newsletter, and much more! CDAIA's mission is to provide more effective communications with District Attorneys’ Offices of California and to develop ways and means of improving our effectiveness as investigators. Our efforts will hopefully promote better coordination between all law enforcement agencies and assist in developing a tighter bond between Investigators throughout California and the nation. Additionally, the CDAIA is also actively involved in the promotion or opposition of legislation that we believe impacts our efforts as district attorney investigators.
