Detective service: Field traces of exploitation

In the workshop, customers often come to me with the question: * “Master, on Avito the seller assures that the camera Used only for home family photography. The shutter travel is short (only 25,000 frames). But how understand that the carcass didn’t plow for 8 hours a day while filming commercial projects?”*.

Here are 4 irrefutable indirect traces of the carcass “from under the video”.

4 Indirect camera markers “from under the video”

1. Broken and loose HDMI / USB-C socket:Videographers always work with external on-camera monitor and cage (Rig). If the plastic around the micro-HDMI is scratched and the connector is loose, remove it from the carcass hundreds of hours of video!
2. Characteristic circular wear around the tripod thread:When the quick release pad is tightened tightly tripod or stabilizer (DJI Ronin), a ring imprint remains on the metal of the bottom of the carcass.
3. A bunch of hot pixels on a heated matrix (Hot Pixels):Start shooting 4K video for 20 minutes. On a heated sensor, a “starry sky” of colored hot pixels will appear - the result of regular thermal overheating
4. An ideal fresh bolt with general wear on the body:Mileage `ShutterCount` is 18,000, but The rubber grip of the handle was swollen with sweat.
