Oversized Merchandise Shipping
Oversized merchandise (Flat screen LED TVs over 55", plasma TVs over 51", BBQ Grills & Furniture) are shipped via a motor freight carrier that specializes in Home Delivery. Since these items are large and fragile, special handling is required, and cannot be shipped via our standard shipping options.
We take every precaution during our shipping preparation process to ensure that your order arrives to you in perfect condition. Each item on your order is scanned for accuracy of model and serial number. We apply large orange fragile sticker labels to notify the carrier that your shipment is fragile and requires special handling. The labels also include important step-by-step instructions on how to inspect and sign for your shipment. In addition to the manufacturer's standard foam and corrugated packaging, we also apply a special shock absorption polyethylene material to the outer carton of every TV. This safeguard will disperse energy from impact during transit, and eliminate damage to the product itself. Our professional appointment-based delivery service allows you to open and inspect your new TV prior to signing and accepting the TV. When you purchase a TV at Beachcamera.com, you can be sure that it will arrive perfect working order, and will remain that way for a long time to come.

PRODUCT HIGHLIGHTS
SILENCIO DESIGN
The Silencio’s minimalistic design cloaks its complexity. Design elements fine-tuned in form and function result in minimized noise and efficiently maintained system temperatures. SILENCIO TECHNOLOGY
SILENCIO TECHNOLOGY
Behind the outer panels are pieces of meticulously placed sound dampening material. The development of the Silencio was driven by Sorama’s Cam64—this allowed for the entire sound spectrum to be visually analyzed by source, resonance pattern, and frequency.
With the identification of peaks within certain frequency ranges, fine-tuning the Silencio for the dispersion of resonance was made possible, reducing the prominence of noise generated by system components. Every detail in design optimized the Silencio for thermal efficiency and silence, from the type of material used to its placement.
SOUND DAMPENING MATERIAL
The Silencio utilizes a combination of sound dampening materials, from thick soft foam to heavy mass-loaded vinyl, to precisely counter prominent frequencies.
SEAMLESS TEMPERED GLASS OR SOUND-DAMPENED STEEL
Available with seamless tempered glass or a sound-dampened steel side panel, systems can be built for show or for stealth with the Silencio.
VENTILATION
TOP
For an even higher demand for ventilation, the top panel’s Sound Dampening Cover can be removed for unrestricted ventilation. An optional dust filter for the top panel ventilation is included, allowing the top panel and front panel work in conjunction to cool the system.
FRONT
The front panel features a recurved vent, directing air in through the front bezel. The curve points downward, taking air in from the bottom, and straightens out to direct air in from either side of the steel front door.
REVERSIBLE STEEL DOOR
The steel front door features a reversible mounting system, capable of opening in either direction. To prevent vibrations, a softer, thicker material spans the steel structure in conjunction with a hinge system of magnets and rubber stompers.
SILENCIO FANS
Two Silencio FP 120mm PWM fans are pre-installed with rubber padding to reduce noise, featuring specially designed blades that allow both quiet operation and high air pressure.
