Lesson 9.3: Installation Best Practices & Commissioning

Module: 9 – Project Management & Lifecycle Prerequisites: Lesson 9.2 (System Design) Estimated Time: 45–60 Minutes

By the end of this lesson, you will be able to:

Demonstrate proper cable management techniques (“Dressing”) inside the rack to ensure serviceability.
Execute a systematic “Focus & Aim” procedure to avoid the dreaded “go-back” trip.
Perform a full Commissioning Test (“The Walk Test”) to verify motion detection and recording.
Create an “As-Built” document package for the final client sign-off.

The difference between a “Trunk Slammer” and a Professional is the back of the rack.

The Rules of Dressing:

Velcro, Not Zip Ties: Inside the rack, use Velcro. Zip ties can crush Cat6 cables (changing their impedance) and are a nightmare to cut off during service calls.
The Service Loop: Always leave 3–5 feet of extra cable slack at the rack end, coiled neatly in the vertical manager or above the ceiling.
- Why: If you need to move the rack or re-terminate a bad jack later, you have slack to work with.
Labeling:Label BOTH ends of the wire.
- Camera End: Label the wire “Cam 01” before you plug it in.
- Patch Panel End: Label the jack “Cam 01.”
- Switch End: Label the patch cord “Cam 01.”
- Result: 5 years later, the tech knows exactly which cable goes to the Loading Dock.

Water is the enemy.

The Drip Loop:

Concept: Never let a wire run straight down into a device. Water will follow the wire like a slide and go right into the port.
Technique: Create a “U” shape in the wire just before it enters the camera. Water runs down, hits the bottom of the “U,” and drips off away from the seal.

Grommets & Silica:

Grommet: The rubber seal on the camera pigtail. If you don’t tighten it, spiders will nest inside and short the pins.
Silica Packet: Most cameras come with a little bag of silica gel. Do not throw it away. Put it inside the dome housing. It absorbs moisture and prevents fogging/condensation on the lens.

Just because the camera is up doesn’t mean it’s done.

The “Helper” App:

Most professional brands (Axis, Hanwha) have a Wi-Fi dongle or app that lets you see the camera view on your phone while standing on the ladder.
Process:
1. Level the horizon (fix the “Dutch Angle”).
2. Zoom to the “Operational Requirement” (Lesson 9.1). Don’t just show “the room”—show “the door.”
3. Focus: Even with Auto-Focus, force a “One-Push Focus” after the dome bubble is installed. (The plastic bubble can shift focus slightly).

WDR Setup:

If the camera faces a window, the image will be dark (silhouette).
Action: Turn WDR (Wide Dynamic Range) ON. It balances the bright sunlight and the dark room.

You cannot invoice until you prove it works.

The Verification List:

Field of View: Does it match the drawing?
Recording Check:
- Action: Wave your hand in front of the camera.
- Verification: Go to the NVR. Playback the video from 2 minutes ago. Did it record?
Motion Masking:
- Action: Check for moving trees/flags in the view.
- Configuration: “Mask” (black out) those areas in the motion settings so they don’t fill the hard drive with false recordings.
Time Sync: Ensure the NVR time matches the actual time. (Critical for legal evidence).

This is what you hand the client to get paid.

Floor Plans: A map showing exactly where Camera 01, 02, etc., are located (with their final IP addresses written next to them).
Device List (Spreadsheet):
- Camera Name | Model | Serial Number | IP Address | MAC Address | Password.
Snapshot Sheet: A PDF showing a thumbnail image from every camera view. This proves the cameras were focused and clean on Day 1.
Training: A 15-minute session teaching the client how to “Search, Playback, and Export” video.
