You bid a 4-camera system. Now they want 12 cameras, access control on every door, and a network closet, all at the original price. Final Bark makes sure every added device and cable run is signed before you pull the first wire.

Low voltage technician installing security cameras

Every low voltage tech has been burned by this

📹

Client adds cameras, sensors, or keypads after the cable is pulled and terminated. Each addition means new home runs back to the panel and NVR upgrades.

🔌

You open the ceiling to run cable and find no pathway. Fire blocking, insulation, and existing ductwork make every run a fishing expedition.

🔐

Access control scope grows from one door to every entry point in the building. Each door needs a reader, strike, power supply, and programming.

Change orders low voltage techs deal with on every project

Additional Cameras & Devices

$500 - $4,000

Client triples the camera count, adds motion sensors, or wants intercom stations. Each device needs cable, termination, power, and programming on the NVR or controller.

Cable Pathway Issues

$800 - $3,000

No conduit, fire-stopped walls, and packed ceiling cavities. Running cable through an existing building takes 3x longer than new construction and may require fishing rods and flex drill bits.

Access Control Expansion

$1,500 - $10,000

Scope grows from a single door to a full building access control system with fob readers, electric strikes, and cloud-based management. Wiring, power supplies, and programming multiply.

Network Infrastructure Upgrades

$800 - $5,000

Existing network can't handle the camera bandwidth. Client needs a new switch, patch panel, UPS, and possibly a dedicated network closet with proper ventilation and power.

Audio & Intercom Systems

$600 - $3,500

Client adds whole-building audio, paging systems, or video intercoms after the security scope is set. Different cable types, amplifiers, and speaker placement add complexity.

Programming & Integration

$400 - $2,500

Client wants cameras tied to their home automation, access control linked to alarm, or remote viewing on their phone. System integration takes hours of programming and testing.
