What happens to my AV system's source code when the programmer leaves?

AV Coding delivers full uncompiled source code to the client of record on every project. A perpetual, transferable licence is included. No lock-in, no expiry. Hand it to any programmer, modify it freely, or archive it. AV Coding retains authorship and will provide the files on request years later.

Do you contact my clients directly?

Never. AV Coding maintains a strict non-compete policy. Subcontracting work stays subcontracted. Your client relationship is yours, full stop.

What is a Crestron Gold Masters Certified programmer?

Gold Masters is among the highest individual certification levels Crestron offers. It requires demonstrated expertise in programming, design, and commissioning beyond standard certification tracks.

Do you work with AV integrators as a subcontractor?

Yes. AV integrators are the primary audience. AV Coding subcontracts Crestron, Biamp, Q-SYS, and Extron programming for integrators across the Northeast US and beyond.

What if my AV system has no source code or documentation?

Legacy code rescue is one of the most requested services. AV Coding diagnoses undocumented systems, recovers files where possible, documents fully, and rebuilds to a standard you can maintain.

Proof Points

Trusted by Institutions That Can't Afford AV to Fail.

"The technical depth bridges the gap between systems engineering and execution. fixing problems unforeseen by installers and interpreting customer expectations into system function. At MIT-Sloan, over a period of years, we have put in a number of facilities of varying purpose and complexity whose control systems were programmed completely by AV Coding."

Ken McCormick Teaching, Learning & Collaboration Space Manager, MIT

"It was a very happy experience to work with AV Coding, who provided top quality work on the audio/video system integration of our conference room, a complicated system including one video conference codec, 3 projectors, 3 TVs, 6 video feeds from a dedicated network, blinds, curtains, and a lighting control system. A system beyond our expectations."

Common Questions

Before the First Call

: Yes, always. Every project includes full uncompiled source code delivered to the client of record under a perpetual, transferable licence. No compiled-only deliverables, no lock-in, no expiry.
: Yes. Subcontracting is a core part of our work. We will not contact your clients directly, ever. Your client relationship is yours, we show up as your programming resource, not as a competing firm.
: Typically within 4 hours during business hours. Emergency and expedited engagements are available at the expedited rate for same-week scheduling.
: Remote programming work is platform-agnostic and location-independent. On-site services are based in Connecticut and cover the Northeast; out-of-region on-site work is considered case by case.
: We hold no dealer agreements, manufacturer incentives, or co-op funding arrangements with Crestron, Biamp, Q-SYS, Extron, or any other manufacturer. When we specify equipment, the recommendation is based on the application, not a sales relationship. Audit findings and specifications are fully defensible for competitive bid.
: Yes. Legacy code rescue and system remediation are among our most-requested services. We start with a documented audit regardless of the system's origin or state of documentation.

Our Process

How We Work

Three checkpoints. You stay in control at every stage. No surprises, no lock-in, no proprietary black-box deliverables.

You Approve Our Scope

We send a written scope of work before anything begins. It covers the deliverables, timeline, platforms, and rate. Nothing starts until you sign off. No ambiguity, no surprise invoices.

You Confirm UI Designs and Working Code

Before final delivery, you review the interface designs and test the working code in a staging environment. Changes at this stage are included, we don't move forward until you are satisfied with what you see.

We Deliver Licensed Source Code

Full, uncompiled source code is delivered to the client of record at project close. You receive a perpetual, transferable licence, take it to any programmer, modify it, archive it. AV Coding retains authorship; the licence never expires. Contact us years later and we will still provide the files.
