Simulcast Auction

An auction conducted simultaneously in-person and online, allowing both floor bidders at the venue and remote bidders on internet platforms to compete on the same lots in real time. The auctioneer manages both channels, calling bids from the floor and the screen.

How It Works in Practice

Simulcast auctions combine the energy of live auctions with the reach of online platforms. The auctioneer calls the sale at normal speed while a clerk or assistant manages the online bidding interface. Platforms like HiBid and Proxibid provide simulcast capabilities where online bidders see and hear the live auctioneer via video stream. This format requires more technical setup (cameras, microphones, stable internet) but consistently generates higher total revenue than either format alone.

Frequently Asked Questions

How does simulcast bidding work?
The auctioneer conducts the sale live at the venue while a bidding platform (HiBid, Proxibid) streams the audio/video to online bidders. A clerk enters floor bids into the system so online bidders can see the current price. Online bidders click to bid, and the auctioneer incorporates their bids into the live call. Both channels compete in real-time on every lot.
What equipment do I need for simulcast auctions?
Minimum: a computer or tablet running the bidding platform, a camera aimed at the auctioneer (built-in laptop camera works for starting), a microphone (headset or lavalier for clarity), and reliable internet (wired preferred, minimum 10 Mbps upload). For professional results: a dedicated camera on a tripod, a wireless microphone, a second screen for the clerk to manage online bids, and a backup internet connection.
