Belltazar
First-Person 5G Broadcast System

See What the Glasses See, Live in Any Browser.

Belltazar is an iPhone companion app + cloud relay that unlocks real-time 30 FPS HD live video from compatible Wi-Fi camera smart glasses over your iPhone's 5G cellular connection. Choose whether you are watching a stream or broadcasting from glasses:

Option A — For the Viewer (No App Needed)

Watch Someone's Live Stream

Use this box if someone wearing smart glasses asked you to watch their live camera feed. Viewers do not need to download an app or create an account — the video plays directly in your browser on any phone, tablet, or computer.

Viewer Instructions: Enter the Room ID from the broadcaster's Belltazar iPhone app (default is live) and click Watch Live Stream. If the broadcaster is still connecting their glasses, the monitor page will stay on standby and start playing video automatically the moment they go live.

Option B — For the Glasses Wearer (Requires Belltazar iPhone App)

How to Connect Your Glasses & Broadcast Over 5G

To broadcast from your smart glasses, you need the Belltazar iOS App on your iPhone. Follow these 4 steps to connect Bluetooth + Wi-Fi and go live:

  1. 01
    Install the Belltazar App & Close Factory Apps
    Install the Belltazar app on your iPhone. Make sure the factory HeyCyan / CyanVue app is swiped closed so it does not block the Bluetooth connection.
  2. 02
    Turn On Glasses, iPhone Bluetooth & 5G Cellular
    Power on your smart glasses and ensure both Bluetooth and 5G / Cellular Data are turned ON on your iPhone.
  3. 03
    Tap "GO LIVE" & Connect to the Glasses Wi-Fi Hotspot
    Tap GO LIVE in the Belltazar app. The app sends a Bluetooth signal that turns on the glasses' built-in Wi-Fi hotspot (named DEVIA Ultra1... or M02S..., default password: 123456789). Tap Join when iOS pops up the Wi-Fi prompt — or open iPhone Settings → Wi-Fi, select the glasses network, and enter password 123456789.
  4. 04
    Stream Over 5G & Share Your Viewer Link
    Belltazar reads the 30 FPS HD camera stream over the local glasses Wi-Fi while simultaneously uploading it over your iPhone's 5G cellular data. Tap Copy Link or Send Link in the app to share your live URL via WhatsApp or SMS.

Buying Guide: How to Know If Smart Glasses Will Work With Belltazar

Whether you already own smart glasses or are shopping for a pair online (Amazon, AliExpress, or retail), look for these exact keywords and specifications — plus our Pro Compatibility Guarantee if your glasses need custom support:

01 / Keywords to Search When Buying

Exact Model & Chipset Keywords

When searching online for compatible smart glasses ($35–$80 range), look for these exact keywords in the product title or specification sheet:

• Model Codes: M02S, A02S, M01, Devia Ultra 1 (DEVIA Ultra1-M02S)
• Chipset Keywords: Allwinner V821, JL7018F + V821
• Camera / Wi-Fi Specs: "800W (8MP) HD Camera" + "Wi-Fi Video Transfer" (avoid Bluetooth audio-only glasses that lack Wi-Fi transfer).

02 / The 1-Second Manual Check

Check the Companion App Name

The easiest way to confirm 100% compatibility before or after buying is to check which factory app the glasses use:

If the seller's description, box, or user manual tells you to download the HeyCyan or CyanVue app, the glasses use the standard DE5BF728 Bluetooth & Wi-Fi RTSP board and are guaranteed to work out of the box with Belltazar.

03 / Pro Compatibility Guarantee
