Signal vs Encrypted Video Calls: What You Need to Know
If you’re diving into the world of secure communication, you’ve probably come across Signal and wondered how it stacks up when it comes to encrypted video calls. As someone who uses Signal daily for messaging and video chats, I can tell you there's more beneath the surface than just “end-to-end encryption.” In this article, I’ll break down Signal vs encrypted video calls, share practical tips, and even some quirks I’ve learned along the way.
What Makes Signal Stand Out for Encrypted Video Calls?
First off, Signal isn’t just another messaging app — it’s built from the ground up with privacy in mind. According to signal.org, every message and call you make on Signal is end-to-end encrypted by default. That means no middleman, no servers snooping, just direct, secure communication between you and your contact.
When it comes to video calls specifically, Signal uses a peer-to-peer connection where possible, which helps minimize the risk of data exposure. The calls are encrypted in transit and at rest, and Signal’s open-source protocol has been audited multiple times for security. So yes, on the Signal vs encrypted video calls front — it’s a solid choice.
How to Make Encrypted Video Calls on Signal: Step-by-Step
If you’re new to Signal’s video calls or just want to be sure you’re doing it right, here’s a quick walkthrough:
- Install Signal: Download Signal from the official app store (Google Play, Apple App Store, or desktop version) or directly from signal.org.
- Set Up Your Profile: Register with your phone number, verify, and add a profile picture if you like. This helps your friends recognize you.
- Start a Conversation: Open a chat with the person you want to video call. If they’re not on Signal, send them an invite—encrypted video calls only work if both sides use Signal.
- Initiate the Video Call: Tap the video camera icon in the chat window's top right corner. Signal will connect the call using its secure protocol.
- Use Group Video Calls: For group calls, tap the video icon in a group chat (up to 8 participants). Signal handles the encryption seamlessly for all parties involved.
One thing I noticed early on: sometimes, if your connection is spotty, the call can lag or drop. Signal doesn’t have fancy background blur or filters like some commercial apps, but its lightweight nature actually helps calls stay stable on slower networks.
Quick Tip:
If your video call doesn’t connect immediately, try toggling airplane mode on and off or switching between Wi-Fi and mobile data. Signal’s connection can be a bit finicky but generally bounces back quickly.
Signal vs Other Encrypted Video Call Apps: What’s Different?
When comparing Signal vs encrypted video calls provided by other apps like WhatsApp, FaceTime, or Zoom, there are some key differences to keep in mind:
- Open Source Transparency: Signal’s codebase is fully open source, meaning anyone can audit it for security flaws. That’s a huge trust factor compared to many proprietary apps.
- No Data Collection: Signal doesn’t collect metadata beyond the minimal info needed to operate (like your phone number), and it doesn’t track or store your calls. Other apps often collect metadata or user data for advertising or analytics.
- Cross-Platform Consistency: Signal works on Android, iOS, and desktop without major feature gaps. Some encrypted apps have limited capabilities on desktop or require extra downloads.
- User Experience: Signal keeps things simple — no filters, no fancy backgrounds, just privacy-first communication. This might feel a bit barebones if you’re used to apps like Zoom, but for me, it’s the tradeoff I’m willing to make.
One minor quirk I’ve noticed: group video calls are currently capped at 8 people on Signal, which is fewer than some competitors. But for small team check-ins or family chats, it’s usually enough.
Pro Tips for Getting the Most Out of Signal’s Encrypted Video Calls
After using Signal for a while, here are a few things I wish I’d known from the start:
- Pin Important Chats: You can pin your favorite contacts or groups to the top of your chat list for quick access to start video calls instantly.
- Use Incognito Keyboard: On Android, enable the “Incognito Keyboard” feature in Signal settings to prevent your keyboard from learning what you type during chats or calls.
- Enable Read Receipts Wisely: If you’re privacy-conscious, note that turning read receipts off affects text messages only — video calls don’t have read receipts but you can still see if calls are missed.
- Switch to Speaker or Mute Easily: During calls, you can quickly switch between speaker and earpiece, or mute yourself by tapping the icons. It’s straightforward but sometimes takes a moment to find if you’re new.
- Use “Note to Self” for Quick Reminders: Want to save a phone number or jot down a quick note from a call? Send it to your “Note to Self” chat — it’s a handy built-in feature.
Heads Up:
Signal video calls don’t automatically save or record (thankfully!), so if you want to keep something, you’ll need to use your device’s screen recording feature. Just be mindful of privacy and always get consent if you’re recording someone else.
Wrapping Up: Signal vs Encrypted Video Calls — Which Should You Pick?
If your priority is privacy and security, Signal’s encrypted video calls are tough to beat. Sure, it might lack some of the bells and whistles of mainstream video apps, but that’s part of its appeal: straightforward, trustworthy communication without hidden data collection.
