Security Cameras with Two-Way Audio for Home and Business
Camius security cameras with two-way audio let you hear live sound, speak to anyone on-site, and record audio alongside 4K video, all from the Camius View app or your NVR. No monthly fees. No subscription. Both wired PoE and wireless systems include built-in microphones and speakers. Shop below or keep reading to see how the feature works.
What Is Two-Way Audio on a Security Camera?
Two-way audio means your security camera has both a microphone and a speaker. You hear sound from the camera location in real time. You speak back through the Camius View app or NVR, and anyone near the camera hears your voice. Camius spotlight cameras also include a siren and white light for active deterrence when motion or a person is detected.
Why These Security Cameras with Two-Way Audio Stand Out
Camius offers professional-grade audio surveillance cameras engineered for seamless integration and reliable performance.
All Camius two-way audio cameras ship with built-in microphones and speakers. No external hardware needed. Supported detection types include motion, sound, person, and vehicle. You adjust audio settings, volume, and encoding format directly in the Camius View app or NVR menu. Choose from wired PoE systems or wireless HaLow NVR systems with up to 2,200 feet of open-air range.
How to Use Two-Way Audio on Camius Security Cameras
- Step 1. Open the Camius View app and select the camera from the channel list.
- Step 2. Tap the microphone icon on the live view screen. You do not need to hold it down.
- Step 3. Speak normally. Anyone near the camera hears your voice through the built-in speaker.
- Step 4. Tap the red end button to stop.Â
Security Cameras with Two-Way Audio for Home Use
Camius security cameras with two-way audio work both indoors and outdoors. From your phone, you confirm a package delivery, speak to a visitor at the door, or tell an intruder you are watching. The Camius View app connects over Wi-Fi or cellular data. Wired PoE systems give you always-on connection. Wireless systems run on rechargeable batteries and add solar panel support for locations without outlets. Solar charges the battery only and does not enable continuous recording.
Security Camera Systems with Audio for Business
Business security camera systems with audio give you live communication at every covered point. Monitor loading docks, entry doors, and parking areas. Speak to delivery drivers or staff without walking to the location. When something unexpected happens, you address it from wherever you are. Camius PoE NVR systems support 8 or 16 channels of 4K video with audio recording, person and vehicle detection, and no recurring subscription costs. Systems scale from 4-camera kits up to 16-camera setups.
Audio Specs for Camius Security Cameras with Two-Way Audio
Camius audio-enabled cameras are built for clarity:
- Camius microphones pick up sound within 9.5 to 16 feet from the camera For best results, mount the camera at the entry point where sound clarity matters most.
- The PoE NVR and hybrid DVR support two audio codec options: G711A and G711U. Set your preferred format under the audio settings menu. G711A is standard for most US networks. Switch to G711U if your network connection shows audio sync issues.
These features ensure that your recorded footage includes relevant context, not just visuals.

Audio recording laws vary by state. Some states require all parties to give consent. Others require only one party to consent. Check your state law before enabling audio recording on any camera.

Frequently Asked Questions About Two-Way Audio Security Cameras
What is two-way audio on a security camera?
Two-way audio means the camera has both a microphone and a speaker. You hear sound from the camera location through the app or NVR. You speak back, and the person near the camera hears your voice in real time.
I tried other wireless systems and the audio kept cutting out. Do Camius cameras hold a stable connection?
Camius wireless cameras use Wi-Fi HaLow, operating at 900 MHz. The signal travels through walls and around obstacles better than standard 2.4 GHz Wi-Fi. Open-air range reaches up to 2,200 feet in lab testing. Real-world results vary based on walls, metal, and terrain.
Which Camius cameras work for outdoor two-way audio?
The 4K outdoor bullet PoE cameras (SPOT828A-RB) supports outdoor two-way audio, active deterrence, a siren, and red and blue warning lights. The SCOUT4K4XPTZ PTZ camera supports two-way audio with auto-tracking and a built-in speaker. Both are weatherproof and work with 4K PoE NVR systems.
Does two-way audio work without internet access on wireless systems?
Yes. Camius wireless NVR systems operate on a local Wi-Fi HaLow network between the cameras and the NVR. Local recording and live viewing work without an internet connection. Two-way audio through the Camius View app requires an internet or LAN connection to reach the feed remotely.
What is the audio recording range on Camius cameras?
Camius microphones pick up sound clearly within 9.5 to 16 feet from the camera. Mount the camera at a covered entry point for best results.
Do Camius systems require a subscription for two-way audio?
No. Two-way audio is a built-in feature on supported Camius 4K spotlight cameras. No monthly subscription or cloud plan is required to use live two-way communication or audio recording.
