Editor's Note: This was previously known as the Eufy Solo IndoorCam C24. Eufy now sells it as the Indoor Cam C120.
Eufy's Solo IndoorCam C24 ($39.99) is a reasonably priced home security camera that doesn't skimp on features. For less than $40 you get 2K video recording, intelligent motion detection, and both local and cloud video storage. It also works with the Amazon Alexa, Apple HomeKit, and Google Assistant platforms, although some features are not available in HomeKit. It performs well and is easy to install, all of which makes it a strong value for a high-resolution indoor security camera.
That said, if you can spare an extra $12, the Eufy Indoor Cam 2K Pan & Tilt offers the same 2K resolution and interoperability, as well as a few extra features, earning it our Editors' Choice award.
A simple design with a lot going for it
The C24 is very similar to the TP-Link Kasa Spot KC400. The white housing measures 2.2 by 2.2 by 1.3 inches (HWD) and has a black camera side. It sits atop a square base that brings the total height to 4 inches. The base is tiltable and rotatable and can be placed on a flat surface or mounted on the wall. The back panel houses a mini USB power port, a sync button, and a speaker, and on the right side, there is a microSD card slot. You must bring your own SD card (up to 128 GB) to store recorded video locally.
The camera captures 2K video and has a 105-degree field of view. It uses eight infrared LEDs for up to 10 meters of black and white night vision and has a built-in microphone for two-way audio and a small LED status indicator. The LED flashes blue during setup, glows blue when everything is working properly, blinks red slowly when connected to the Internet, blinks red once when sound or motion is detected, and glows red when the camera is recording an event.
The C24 will send push notifications and record video when motion or sound is detected, and knows the difference between motion caused by people, pets, and other disturbances. It also has a setting that activates an alert when it detects the sound of a baby crying. The camera stores video locally on a microSD card or on a NAS drive, or you can subscribe to a Eufy storage plan to have video stored in the cloud. For $2.99 per month or $29.99 per year, the basic plan offers 30 days of video storage for one camera. The Premier plan costs $9.99 per month or $99.99 per year and gives you 30 days of video history for up to ten cameras.
As with the Eufy Indoor Cam 2K Pan & Tilt camera, the C24 supports Apple HomeKit and Siri voice commands, but certain features are not available when using HomeKit, including activity zones, pet commands, and sound detection. Most importantly, video streaming and recording are limited to 1080p in both the Eufy app and the Apple Home app. The C24 also supports voice commands from Amazon Alexa and Google Assistant and works with routines for both platforms, but it doesn't support IFTTT applets that allow it to communicate with dozens of third-party devices.
The C24 uses the same Eufy Security app (for Android and iOS) as other Eufy cameras. It appears on the Devices screen with a freeze frame of the last recorded motion event and a playback arrow. Tap the arrow to start a live stream with buttons along the bottom for manual recording, taking a screenshot, initiating two-way calls, sounding the internal siren, and muting the sound. If you turn your phone sideways, you can watch the stream in full screen. Tapping the gear icon in the top right corner will take you to the Camera settings screen. Here you can turn the camera on and off, enable automatic night vision, configure motion and sound detection settings (including people and pet detection), choose a video quality setting for streaming and recording, enable notifications, and enable continuous recording if you have a microSD card installed. There's also a Pet Command feature that plays a recording when the camera detects a pet. You can use the included "Hey, what are you doing there" response or create your own custom recording using your voice.
Installing and Using the Eufy Solo IndoorCam C24
You'll need to download the mobile app and create an account to install the C24, but once that's done, setup is quick and easy. I opened the app, tapped Add Device on the Devices screen, and selected IndoorCam from the list. I connected the camera, and when the LED turned solid blue, I tapped Next and scanned the QR code on the base station with my phone's camera. I held down the sync button for two seconds until I heard a beep, verified the beep, and selected my Wi-Fi SSID from the list of nearby networks. I entered my Wi-Fi password, and after a few seconds, the camera was connected. I gave it a name, formatted an SD card I had installed, updated the firmware, and the installation was complete.
The C24 delivered sharp 2K video during testing. Daytime colors appeared rich and saturated, and nighttime black-and-white images showed balanced contrast with good lighting. There was a hint of barrel distortion around the edges, but the error is small and barely noticeable. Motion and sound alerts came in immediately, as did recorded video using the microSD card slot. Intelligent motion detection worked well for filtering out motion events from everyone except people and pets. The crying baby sound filter also worked as intended. The recorded video of the event looked just as sharp as the live feed, and the two-way audio was clear and sufficiently loud. I had no problems viewing video from the camera on an Amazon Echo Show using voice commands, and my Alexa routine to turn on a Wyze Bulb when the camera detected motion worked flawlessly.
Ultra-Affordable 2K Security
At $39.99, the Eufy Solo IndoorCam C24 replaces the $44.99 TP-Link Kasa Spot 24/7 Recording (KC400) as the most affordable 2K indoor security camera we tested. It delivered very detailed video during testing and worked well with Alexa voice commands and routines, and its intelligent motion and sound detection features were just as seamless. That said, if you need an indoor camera that offers a view of the entire room, our Editors' Choice winner, the $51.99 Eufy Indoor Cam 2K Pan & Tilt, offers the same sharp 2K video and automatic motion tracking for just $12 more. For an even more affordable Wi-Fi camera that works indoors and outdoors and offers color night vision, try the $35.98 Wyze Cam V3, another Editors' Choice winner.
