Design & Build

The Eufy Solocam S40 2K Security Camera comes with a built-in solar panel and 8GB of onboard storage. The camera can be mounted anywhere, as long as it has a strong signal from your router. The solar panel on top of the camera is black, not shiny. The SolarCam S40 is weatherproof so it can stand up to harsh conditions. The USB-C port lets you charge your device via power from the sun.

Features & Performance

The Eufy Solocam S40 2K Security Camera is easy to set up and has a range of features. The camera automatically detects people and animals, with the goal of capturing time-lapse videos (10-20 seconds). The Eufy Solocam S40 is compatible with the Eufy app and uses QR codes to connect. The camera can maintain a Wi-Fi connection from 20 meters away. The app gives you thumbnails from any Eufy cameras you have installed.

The S40 captures short video clips when motion has been detected, not continuously. There are three recording modes for the SoloCam S40 2K Security Camera; “Motion Detection” mode records 10-20 seconds of footage after detecting movement, while the “Optimal Surveillance” mode records until movement stops (up to two minutes), regardless of how long it takes for that activity zone(s) to be clear again. If a motion is detected within an activity zone that you have previously designated, then the “Custom Recording” mode will record for the length of time that you’ve set in advance (between 1 and 60 minutes).

The camera does not have an option to retain footage for an extended length of time, with the default being 10-20 seconds and a maximum length of two minutes. The longest duration is only available in “Optimal Surveillance” mode, which gives users some control over how long recordings last.

The camera can record up to two hours of HD video. The S40 has a built-in motion sensor which will trigger an alert on your iOS device when it detects an incident. The 2K resolution and 130° lens give high-quality images. The camera is also suitable for nighttime use, with colour footage captured well when using the 600-lumen spotlight.

The Solocam S40 is easy to set up and use; the flood light on the S40 causes a taxing battery life, so it should be used sparingly (it’s best to keep it turned off). The audio quality from the microphone is excellent, even in adverse weather conditions. AI allows you to filter out smaller movements that could indicate a person, animal or something else.

The Solocam S40 is a 2K security camera that can be set to only detect movement within certain activity zones by activating crying detection (which makes the device unable to distinguish between humans and objects). This setting worked well during our tests but did generate one false alarm.

The camera can use your phone’s microphone as a two-way communication device. The app offers some really convenient controls for the built-in motion sensors and light, but it would be better if they were on the main screen.

The camera is built with a solar-powered battery that loses 1 to 2 percent each day, falling between 63 and 64 percent by the end of testing; this means that you’ll need to charge it every few days (the light has only short burst use).

Price & Availability

The SoloCam S40 is more expensive than the SoloCam E40, but this may be due to its larger size. The S40 comes in at around $199 and has a solar panel for power. It can be purchased on Amazon, Walmart and eBay.

Video quality

The camera captures great footage at all times of the day and night. The Eufy SoloCam S40 has excellent daytime visibility up to 2K resolution. It is designed for outdoor use; it can be left outside without any need for maintenance or charging by solar power alone. The Eufy SoloCam S40 is good at capturing footage in both black and white, as well as color. The camera does have some blurring problems on grass or brick surfaces but overall the video quality is impressive, especially when compared to other security cameras in this price range.

Power Options and Battery life

The SoloCam S40 2K Security Camera comes with a built-in solar panel that charges the battery automatically. The camera needs eight hours to fully charge the battery, and it lasts for up to four months if you record five minutes a day.

The battery life of the SoloCam S40 2K Security Camera is dependent on how often it detects motion, how often it’s viewed live and if the siren is triggered. If all of those things are happening regularly, then you can expect about two months of use on a full charge. However, if motion is only detected every other day and you only view live footage once a week, then the battery will last around four months. The camera also has a Power Manager feature that you can use for battery conservation.

Smart Home Integration

The SoloCam S40 2K Security Camera allows you to see a list of installed cameras and their most recent motion detection. The camera’s live feed displays in real-time or can be watched from the Events tab at the bottom. The most common settings for each camera are customizable from this screen by tapping on them.

Smartphone App

You can change settings like spotlight color temperature, toggle notifications on and off, monitor battery life and storage levels, and more. The app is where to find all of your security camera’s information – from battery life to storage levels to solar charging efficiency statistics.

Does SoloCam s40 require HomeBase?

The SoloCam S40 does not require the HomeBase to operate, which is a plus. The SoloCam S40’s strengths are that it does not need HomeBase but its weaknesses include the inability to back up recorded footage unless on cloud storage It is tempting to compare this outdoor camera to the ones from Nest, Arlo, and Canary; however, SoloCam S40 has a solar panel and battery which offer unlimited power supply and can last for up to three hours of use without charging.
