Silent Observer (SIOB)

Silent Observer is the first invention of Magnum OpusTM used in the Kolhapur district of Maharashtra. Silent Observer has lots of limitations as it was done for the first time, such as it has on and off button, the storage capacity was 320 GB to 500 GB, it was not recording contentiously etc.

How ever, the all the drawbacks were removed and a new device was invented and named as Active Tracker.

All the silent observers were replaced by Active Tracker and Magnum OpusTM does not manufactures Silent observer now.

The Government of Maharashtra has appointed a committee to evaluate the Silent observer system and reported negatively about its drawbacks. The same committee visited again to evaluate the Active Tracker system and they were satisfied with the Active Tracker system.

Here is a comparison of the Silent Observer, Active Tracker & Active Tracker+ with respect to the guidelines issued by the MP state:
