Layer the site so one failed control does not expose the tools.
A strong lock matters. A visible location, controlled keys, lighting and a named nightly closer matter just as much.
Recommendations that survive an active jobsite.
A camera directly above the doors often records helmets and hats rather than faces. Add an approach angle at usable height.
Test the scene after dark with the actual work lights on. Reflective vests and white doors can overexpose the image.
Keep the recorder or communications equipment outside the container being protected.
Use tamper and offline alerts so a disconnected camera produces an action, not just missing footage.
Working checklist.
Assign an owner, record exceptions and close the loop before the next phase begins.
- Capture license plates at the vehicle approach
- Capture faces at the pedestrian approach
- Eliminate backlight and IR reflection
- Confirm network or local recording health
- Set an escalation contact
- Review footage after layout changes
Common mistakes that create cost later.
Pointing every camera at the same door angle
Mounting lights behind the subject
Putting all equipment on one easy-to-cut power source
Using GPS without an owner who receives alerts
Short answers before you act.
Is one camera enough?
One camera can confirm activity, but two angles are usually needed to capture both the approach and the actual door interaction.
Where should a tracker go?
Use trackers on selected high-value mobile assets and follow the device manufacturer's installation and legal guidance.
