Choose the E340 when seeing parcels at your feet is the priority; choose the C31 when you want a wired, continuous recording setup. The extra downward-facing camera is the E340’s real selling point. The C31’s useful advantage is a documented continuous-recording route, with wiring conditions that matter more than the headline resolution. For a typical porch buyer who mainly wants visitor alerts, start with the C31 and pay more only for a clearer view of the doorstep.

The choices that change daily use

A parcel view and a continuous timeline answer different questions. The former helps you see what is sitting below the doorbell; the latter helps you review what happened between alerts. Decide which missing information has caused you trouble before choosing.
Will the extra camera help with deliveries?
The E340’s front camera watches visitors while the downward-facing camera covers the floor immediately outside the door. That is useful if a courier leaves a bag close to the wall, where a visitor-focused view can make it awkward to check. We would pay for it for a busy delivery doorstep, especially when you regularly open the app just to see whether a parcel remains there.
The C31 page describes a view of the front-door area. Before spending more, stand at the intended mounting point and consider where deliveries actually land. A camera view still cannot see through a gate, furniture or the parcel itself. Moving a delivery spot into view can matter more than buying a different camera. Neither product’s published resolution tells us how readable a label will be in your lighting; this is a documentation comparison, not a footage test.
What does continuous recording require on C31?
The C31 supports pre-recording and continuous recording with the specified transformer: Yes, Video Doorbell C31 supports the pre-record and 24/7 recording functions when powered by a 16-24V, 30VA transformer. The existing chime must be bypassed to enable those modes. Include a suitable way to hear doorbell presses in the installation plan instead of discovering the chime change after mounting it.
The E340’s wired connection keeps its installed battery topped up. That is a charging arrangement, not a reason to treat every wired doorbell as the same recording system. For someone specifically buying a continuous timeline, we choose the C31’s documented setup. For a renter using battery power, that advantage should not determine the purchase: choose around framing and how you will recharge instead.
Which setup costs less to start?
The checked manufacturer listings show E340 at $149.99 and C31 at $99.99, a hardware difference of $50.00 excluding any unlisted checkout adjustments. Those are direct-store reference prices, not a promise about the retailer reached through a buying button.
The E340 has onboard storage. The C31 takes a separately purchased card; wiring work and the chime arrangement can also change its installed cost. Compare the complete configuration rather than subtracting sticker prices and stopping there. Both provide a local-recording route without a required cloud-storage subscription. Optional cloud backup is a separate decision. Export an important incident instead of assuming local history is a permanent archive.
Our pick for frequent deliveries
Buy E340 if the doorstep itself is what you keep struggling to see. Its downward camera addresses that task directly. Keep an existing C31 if its current view already shows your delivery area clearly; the presence of another lens is not, by itself, a reason to replace working equipment.
Our pick for reviewing the full day
Choose C31 with suitable wiring when gaps between triggered events are the problem. Budget for the card and check the transformer and chime before ordering. If that installation is impractical, do not buy on the continuous-recording promise and hope battery mode provides the same thing.
Frequently asked questions
Does wiring the E340 let me remove its battery?
No. Eufy says the battery remains installed in wired mode because the doorbell still uses it for power. Wiring reduces the need to recharge it separately; it does not turn the product into a battery-free installation.
Can C31 record continuously while running on battery?
The continuous-recording setup documented here requires the specified transformer and bypassing the existing chime. Choose battery mode for installation flexibility, and do not base a battery-only purchase on the wired mode’s recording features.
Do I need to buy a hub immediately?
Both doorbells have standalone local-storage arrangements. Start with the recording and chime setup you need. A central-storage accessory may be useful later, but it should solve a defined requirement rather than be an automatic addition to the cart.
Which doorbell would you buy for an ordinary front door?
We would start with C31 when its view covers both visitors and the delivery spot. We would choose E340 when the floor immediately below the doorbell is difficult to see and checking parcels is a frequent task.
