  • At the crime scene: Capture 360-degree floor-to-ceiling spherical photos to preserve the scene exactly as you saw it during your investigation (or, if an investigator from a law enforcement agency was on-scene before you, you can use their “first on scene” OSCR photos and go from there). Each photo is automatically time-stamped and includes GPS coordinates of where the photo was captured. 
  • In the DA’s office: Using your OSCR photo(s), create an entire case file that includes the multimedia evidence you have for the case. This could include close-up evidence photos, video/audio recordings, body cam footage and more. OSCR is user-friendly, secure, and shareable – but only with those whom you choose to share it with.  
  • In the courtroom: OSCR presentations have been used and accepted in the courtroom – they are admissible in court. The interactive presentation essentially gives the jurors and the courtroom audience an opportunity to virtually walk through the crime scene. They view the scene as if they were in your shoes – from the point of view of the investigator. OSCR presentations are a compelling, seamless and organized way to present a case.
