Evidence Rooms

FaceKey Biometrics
Protects Evidence for Trial

The purpose of evidence rooms is to catalog and protect the evidence collected from crime scenes and ensure that the evidence will not be contaminated for future court proceedings. The chain of custody is key to a successful outcome of any court trial. Law enforcement must be able to show that access to the evidence room is controlled to protect the chain of custody. Today, police department’s evidence rooms are generally secured with a simple lock and key, a proximity card, and/or a PIN code. These systems of security can easily be compromised by theft, copying, sharing or loss.

Biometric technology can provide law enforcement with the highest accountability possible. Biometric access ensures that only authorized personnel can gain access to evidence rooms. Records and reports form an accurate and accountable audit trail of access, egress and amount of time an individual spent in the evidence room. A biometric access control system will protect law enforcement personnel rom fraudulent claims of tampering with the evidence, and the chain of custody is strengthened when cases go to trial.

George Little, a 14 year veteran evidence room custodian and current Director of the Institute for Criminal Justice Studies at Texas State University, cited this recent problem as just one example of the shortcomings of the current evidence room model:


Mr. Little stated that new safeguards must be put in place to stop the tampering of evidence rooms. He suggested that biometric access control can tie into a video surveillance system and complete a 100% accountable, reliable and accurate chain of custody model.
