“We hired Jellyfish Shield to install access control across three commercial properties. The team was incredibly organized, finished ahead of schedule, and the systems have been rock solid for over a year now.”

Frequently Asked Questions
Everything you need to know before your first project with Jellyfish Shield. Still have questions? Just reach out.
Low voltage work covers any system that runs on 50 volts or less — things like network cabling, security cameras, smart home systems, audio/visual setups, access control, and alarm systems. It's separate from standard electrical work and requires specialized licensing and training.
Yes, absolutely. Jellyfish Shield holds all required California low voltage contractor licenses and carries full general liability insurance. We're happy to provide proof of insurance and licensing before any work begins — just ask.
We serve all of Southern California including Los Angeles, San Diego, Orange County, Riverside, Long Beach, Anaheim, and the surrounding communities. If you're unsure whether we cover your area, give us a call at 999-999-9999 and we'll confirm right away.
It depends on the scope. A single security camera or network drop can be done in a few hours. A full smart home integration or commercial cabling project may take 1–3 days. We always provide a detailed timeline upfront so you know exactly what to expect before we start.
We use transparent flat-rate pricing — no hourly surprises. After an initial consultation (free of charge), we provide a detailed written quote covering all labor and materials. The price you approve is the price you pay. No hidden fees, ever.
Yes! We serve both homeowners and commercial clients — from single-family homes and condos to retail stores, office buildings, restaurants, and multi-unit properties. Our team is experienced with projects of all sizes.
We take great pride in clean, minimally invasive installations. We use fish tapes, drill guides, and professional concealment techniques to route cables without unnecessary damage. Any minor access points are patched and finished before we leave.
Yes — all our installations come with a workmanship warranty. We also offer ongoing support for troubleshooting, system upgrades, and expansions. If something isn't working right after we leave, just call us and we'll make it right.
