Photo booth internet at events: how much upload you need and how to set up the WiFi

Why does a photo booth need upload rather than download?

Photo booths are a fixture at end-of-year functions, weddings, brand activations and awards nights. Most now share images on the spot: a guest takes a photo, types an email address or phone number, or scans a QR code, and the picture arrives on their phone a few seconds later. Every one of those steps sends files out of the venue.

• Sharing: each session uploads photos, GIFs or clips to the booth's online gallery, which then sends the email, text message or link.
• Galleries and screens: some booths also upload every image to a live gallery or a screen slideshow.
• Social posts: guests then download and repost, which adds load on whatever network they are using.

Speed tests usually headline the download figure, but many connections have far less upload than download. A venue that streams video comfortably can still be slow to send dozens of large files. Our guide to upload speed for live streaming explains why upload is the figure to check, and the bandwidth calculator helps total it across every use at the event.

How much upload does a photo booth need?

Upload depends on the booth type, the file settings and how quickly guests expect their images. These are planning estimates. Check the booth software's own export settings for exact file sizes.

Worked example

A 150-guest end-of-year party runs a still-photo booth. Each session sends about 15 MB, and guests expect it within 30 seconds:

1. 15 MB is 120 megabits.
2. 120 megabits in 30 seconds needs 4 Mbps of upload while that session sends.
3. Add 1.5 to 2 times headroom for retries and overlapping sessions: 6 to 8 Mbps of stable upload.

Swap that booth for a 360 booth sending 50 MB clips and the same calculation gives about 13 Mbps per clip, or 20 to 26 Mbps with headroom. If two booths run at once, add them together.

Which connection should the booth use?

The booth is usually set up by a supplier who arrives an hour before guests. Agree on the connection in advance, in this order of preference:

1. A wired connection or a dedicated network segment on the event or venue network, with its own password and a reserved share of the upload.
2. A dedicated 4G or 5G router placed where the signal is strongest, connected to the booth by cable or a short WiFi link. See 4G and 5G router hire.
3. Venue WiFi only if the venue confirms the upload speed and lets the booth join a network separate from guests.

Avoid putting the booth on the guest WiFi. When 150 guests join the same network at once, the booth competes with every phone in the room, and the queue slows exactly when the dance floor fills. Our guide on why venue WiFi fails at events explains the pattern, and guest WiFi covers how to keep guests on their own network.

What happens if the internet drops during the event?

Most booth software can store sessions locally and send them when the connection returns. Turn that on and test it before guests arrive.

• Offline queue: confirm the booth saves every session on its own storage and retries automatically.
• Tell guests: a short on-screen line such as 'Your photos will arrive shortly' saves the attendant from repeated questions.
• Second connection: for larger events, a backup connection on a different network keeps sharing moving if the main link fails. See backup internet.
• Power: place the booth and its router on a circuit that is not shared with heaters, urns or catering equipment, so a tripped circuit does not take both down.
• After the event: make sure the online gallery is complete before the supplier packs down, and check that the queue is empty.

What privacy and security steps apply to photo sharing?

When guests type an email address or phone number to receive their photos, the booth is collecting personal information. Under Australian Privacy Principle 5, an organisation covered by the Privacy Act must take reasonable steps to notify people at or before the time of collection, or as soon as practicable after. The Office of the Australian Information Commissioner lists matters such as who is collecting the information, why, and who it is usually disclosed to, including any overseas recipients.

• Show a short collection notice on the booth screen before guests enter their details.
• Collect only what is needed to send the photos.
• Agree with the supplier how long images and contact details are kept, and where the online gallery is hosted.

On the network side, the Australian Cyber Security Centre recommends changing default router login details, using WPA3 encryption (or WPA3 transition mode or WPA2 where devices cannot use it), and placing visitors and untrusted devices on a separate guest network. This is general information, not legal advice. Our guide to event WiFi security covers the network settings in more detail.

Photo booth network checklist for organisers and suppliers

1. Ask the supplier for the booth type, file sizes and the upload speed they need.
2. Check the actual upload speed at the booth position, at the time of day the event runs.
3. Give the booth its own network or a dedicated router, with a password not shared with guests.
4. Turn on the offline queue and test sharing to a phone on a different network.
5. Plan a backup connection if the booth is a centrepiece of the night.
6. Agree the collection notice and data retention with the supplier.

If you are planning a function, wedding or brand activation with a photo booth, live stream or payments, send us the venue and the run sheet and we will come back with a network plan. Start on the contact page, or see corporate event WiFi and brand activation WiFi.
