How Do I Set Up the eufy SoloCam S340 Dual Lens?
- Connecting to 5GHz not 2.4GHz
- Weak 2.4GHz at the mount
- Battery not charged before setup
Problem Description
You are setting up the eufy SoloCam S340 dual-lens camera. The S340 has two lenses — a wide-angle lens and a telephoto lens that provides 8x hybrid zoom. Charge the camera fully via USB-C on the back before mounting. It connects directly to WiFi and stores footage on-device. This guide covers charging, mounting with the included bracket, and app setup.
Why This Happens in Real Homes
The eufy SoloCam S340 is a standalone, solar-powered camera with two lenses — a wide-angle and a telephoto for optical zoom — plus pan and tilt, all over 2.4GHz WiFi with no HomeBase needed. Setup is the standard wire-free flow, with the same 5GHz and QR-scan snags as other SoloCams.
Charge it, put it in pairing mode, and join a 2.4GHz network (not 5GHz) with the correct password, holding the QR code at the app's suggested distance until it chimes. Ensure strong 2.4GHz where you mount it, since it streams and stores locally, and install any firmware. Aim the built-in solar panel at direct sun so its pan/tilt and dual lenses stay powered.
Symptoms
- Setting up the SoloCam S340
- Dual-lens/zoom questions
- Won't connect to WiFi
- App can't find it
- QR won't scan
- Pan/tilt/solar setup
- Won't pair
- Offline after setup
Recognize these? Here's what usually causes it.
Common Causes
- Connecting to 5GHz not 2.4GHz
- Weak 2.4GHz at the mount
- Battery not charged before setup
- QR code at the wrong distance
- Not in pairing mode
- Wrong WiFi password
- Firmware update pending
- Router blocking the device
Most fixes happen in the first 3 steps.
Security cameras should be installed at least 8 feet high to prevent tampering. Check local laws regarding recording audio and video. Never aim cameras at neighboring private property. Outdoor cameras should be rated IP65 or higher for weather resistance.
Tools & Requirements
Step-by-Step Solution
Charge and mount the SoloCam S340
The eufy SoloCam S340 has a built-in battery. Charge fully via USB-C before mounting (8-10 hours). The S340 has dual lenses — a wide-angle lens for overview and a telephoto lens with 8x zoom for detail. The camera physically rotates 360 degrees horizontally and tilts 70 degrees vertically using a motorized pan-tilt mechanism. Mount it on a high point (8-10 feet) with a clear sightline in all directions to take advantage of the 360-degree rotation.
Set up in the eufy Security app
Open the eufy Security app and tap + > Add Device > SoloCam S340. Scan the QR code with the camera. Connect to your 2.4GHz WiFi. The S340 connects directly to WiFi — no HomeBase required. After setup, the app shows a live view with controls for pan, tilt, and zoom. You can also add it to a HomeBase 3 for centralized storage if you have one.
Configure the dual-lens tracking
The S340 has AI-powered tracking that follows moving objects. When a person enters the camera view, the wide-angle lens detects them, and the camera motor physically rotates to keep the person centered in frame. The telephoto lens simultaneously provides a zoomed-in view. In the eufy app, enable Motion Tracking in the camera settings. You can set whether the camera returns to its home position after tracking ends (recommended) or stays pointing at the last position.
Set up preset patrol points
In the eufy app, go to the camera > Pan & Tilt > Patrol. Set patrol points — positions the camera rotates between on a timer. Example: point 1 covers the front door, point 2 covers the driveway, point 3 covers the side yard. The camera rotates through these positions at an interval you choose (every 10, 30, or 60 seconds). Patrolling provides broader coverage than a fixed camera but uses more battery due to the motor running.
Manage battery with pan-tilt features
The motorized pan-tilt mechanism uses significant battery power. Continuous patrol mode can drain the battery in 1-2 months instead of the 3-4 months with a fixed position. Use patrol mode sparingly — run it during away hours and disable it when home. Use the solar panel accessory (eufy Solar Panel) to offset motor power consumption if you want continuous patrol. Mount the solar panel facing south for maximum sun exposure.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If this comes back after following these steps, check whether a recent app or firmware update reset a default setting — the fix works, but the setting gets reverted silently.
Set up activity zones to monitor only the areas that matter like your front porch and driveway and exclude the street. This dramatically reduces false alerts while ensuring you never miss an actual event at your property.
Battery-related failures are almost always flagged too late — the device degrades silently for days before the app catches up to what's actually happening.
