The short answer: The Eufy Video Doorbell S330 is the E340's smarter sibling — dual cameras, Delivery Guard™, and radar-plus-PIR Dual Motion Detection that cuts false alerts by 95%. No subscription. No monthly fees. If parcel security and precise alerts matter more to you than colour night vision, the S330 is the better Eufy.
S330 vs E340 — Why Does This Exist?
After 20 years in UK security, I've seen homeowners buy the wrong version of a product because the differences weren't explained clearly. So let's start there.
Both the S330 and E340 have dual cameras. Both are subscription-free. Both are IP65 and work with Alexa and Google Home. But they are different doorbells aimed at different priorities:
E340: Colour night vision, 8GB built-in storage (no hub required), longer battery life. Better for low-light identification.
S330: Dual Motion Detection (PIR + radar), Delivery Guard™, Motion-Activated LED light on package camera, 16GB HomeBase 2 storage. Better for parcel protection and precise alerts.
If you get a lot of deliveries and false alerts are a problem, buy the S330. If colour night vision and simpler setup matter more, buy the E340.

Video Quality
Daytime
Main camera: 2K at 2560×1920 pixels — identical resolution to the E340. The 160° diagonal field of view (120° horizontal) is wide enough for most UK terraced house doorsteps and covers the full path to the door.
Package camera: 1080p at 1600×1200 — also identical to the E340, angled downward to capture the doorstep, parcels, and anyone crouching near deliveries. The addition of a Motion-Activated LED light on the package camera is the S330's practical advantage: it illuminates the porch automatically when triggered, making package footage usable even in low light — and deterring porch pirates at the same time.
Night
Infrared night vision — black and white. This is the S330's main trade-off versus the E340. The E340 has colour night vision; the S330 uses 4 infrared sensors for B&W footage. In UK street lighting conditions, you'll get clear footage up to 4–5 metres, suitable for identification — but without the colour detail that makes clothing and vehicles identifiable at a glance.
If colour night vision is essential, the E340 is the better choice. If you care more about false alert precision and package protection than colour night footage, the S330's trade-off is acceptable.
Dual Motion Detection — The S330's Headline Feature
Standard doorbells use a single motion sensor — either passive infrared (PIR) which detects heat signatures, or radar which detects movement. Each has blind spots.
The S330 uses both simultaneously. PIR detects a warm body approaching. Radar scans for movement. Only when both sensors agree is an alert triggered — reducing false alarms by 95% according to eufy's own testing.
In practice on a busy East London street: a car driving past no longer triggers an alert. A leaf blowing past the door no longer triggers an alert. The person who actually walks up to your door — triggers an alert.
After 20 years watching homeowners disable doorbell alerts because of constant false triggers, this feature is more valuable than it sounds. A doorbell you stop checking because it cries wolf is no doorbell at all.
Delivery Guard™
The S330's exclusive feature — and genuinely useful for UK homes.
When a parcel is detected at the door, Delivery Guard activates and monitors it continuously. If anyone approaches the package, an automatic voice message is broadcast through the doorbell speaker: "Your actions are being recorded." Pick-up reminders alert you to collect your delivery before it gets dark.
In a country where 4.83 million households had a parcel stolen last year — see our parcel theft guide — this is a meaningful deterrent, not just a marketing feature.
App & Setup
Setup is via the eufy Security app. The HomeBase 2 plugs into your router via Ethernet and acts as a hub: it stores 16GB of footage locally, provides the chime, and extends Wi-Fi range to the doorbell.
The doorbell itself connects to the HomeBase rather than directly to your home Wi-Fi, which means a more stable connection even in homes with weaker Wi-Fi at the front door — a common issue in UK terraced houses with thick walls.
Without subscription: Full functionality. All motion events recorded locally to HomeBase. Person and package detection. Delivery Guard. No cloud required.
With optional cloud: eufy offers cloud backup as an optional paid feature — not required for the doorbell to function fully.

Who Should Buy the Eufy S330
Buy it if:
- False motion alerts are your biggest frustration — radar + PIR solves this
- You receive a lot of deliveries and want active parcel protection
- You want no subscription and local storage
- Precise, reliable alerts matter more than colour night footage
Don't buy it if:
- Colour night vision is essential — buy the Eufy E340
- You want the simplest possible setup — E340 needs no hub, S330 requires HomeBase
- You rent and want the most portable option — see our renters guide
- You need Apple HomeKit — see our HomeKit guide
My Verdict — 8/10
The Eufy Video Doorbell S330 solves the problem that irritates most doorbell owners more than anything else: false alerts. Dual Motion Detection with PIR and radar is the right answer to a real problem — and no competitor in this price range offers it without a subscription.
The infrared-only night vision is a genuine compromise versus the E340. At £199 (£40 more than the E340), you're paying for smarter detection and Delivery Guard at the cost of colour night footage. For most UK homes that receive regular deliveries and are tired of constant irrelevant alerts, that's a reasonable trade.
For subscription-free dual camera protection with the sharpest night vision, the E340 remains the better all-rounder. For subscription-free dual camera protection with the most intelligent detection and active parcel security, the S330 earns its price.
