Below you will find several issues associated with canvassing for surveillance video and how the Camera Canvass Tracker assists with these issues.

Issue 1: Locating the surveillance video

  • Have you ever had to canvass for a video camera at night, on a dark street, with few street lights?
  • This is very difficult and you often return back the next morning to find out that you missed a surveillance camera and lost valuable investigative time.
    • If you used Camera Canvass Tracker, you would enter and store the camera location so the next time your investigation leads you to the same block, you already know where the cameras are!

Issue 2: Locating the person who maintains control of the system, who will supply the password and grant access to view/download the video.

  • Have you ever had difficulty locating the “super” and when you finally do, you learn that they have to call the building manager to gain access to the system?
    • If you used Camera Canvass Tracker, you would store the contact information and other DVR details so that the next time you have to return to the same location for a new investigation you would know who to call to gain access and where to go to retrieve the video.
    • You would even have the password to the device that worked the last time you visited the location!

Issue 3: Calculating the time difference when you are standing in front of a DVR that has the incorrect time on it.

  • Have you ever attempted to locate your incident on a video when the DVR time is off by days, hours, minutes, and sometimes even years?
  • This is very time consuming and leaves room for human error.
    • Example:
      • The time you are standing in front of the DVR is: May 5th, 2016 @0330 hours
      • The time shown on the live DVR as you stand there is: September 18, 2013 @ 1426 hours
      • The crime you are investigating occurred on: May 4, 2016 @ 2345 hours
      • Did you calculate the DVR to be off by 959 days 13 hours and 4 minutes?
      • Did you figure out that you have to turn the DVR to 9/18/13 at 1041 hours to find your incident?
      • This took about 40 seconds with Camera Canvass Tracker and removed the risk of human error. It also left you with a permanent record of your calculations for your case folder.

Issue 4: Testimony regarding the recovery of the video, the name of the location, time you recovered it, and what the time was on the DVR when you recovered it.

  • Have you ever been cross-examined regarding the discrepancy between the time stamp of the video and the incident time of the crime you’re investigating?
  • Have you ever heard the defense say it could not have possibly been the crime because the times do not line up?
    • The Camera Canvass Tracker will leave you with a time stamp every time you use it and will document the calculations showing the time differences.
    • You will also have the documentation to support that showing, the location name, address, contact person, and all of the calculations that you performed.

How does CAMERA CANVASS TRACKER eliminate these issues?
