eufy Floodlight Camera E340 Installation in London
Updated
The Floodlight Camera E340 is eufy's model T8425, a different product from the Video Doorbell E340 that shares its name. On 31 October 2026 it was the only floodlight camera on sale on eufy's UK store, with the Floodlight Camera E30 sold out. It is a mains light fitting with two cameras, wired at 100–240 V AC. A JACK pro in London swaps it for the outside light you already have and connects it to that light's supply, and the price is fixed in the app before you book.
In short
Yes. A Jack All Trades (JACK) pro in London can replace an existing outside light with the eufy Floodlight Camera E340 on the same circuit, using the old light's wiring at 100–240 V AC with a working earth and no dimmer or timer in the supply; in England that is not notifiable under Part P, and the pro leaves a Minor Electrical Installation Works Certificate. eufy's UK FAQ says that outside North America installation and wiring 'must be performed by a licensed electrician'; England has no such licence, and a job that needs a new circuit goes to a registered electrician, which JACK does not book.

How the Floodlight Camera E340 is powered and mounted
The E340 is a light fitting with two cameras built in, so it draws its power from the mains exactly as the outside light it replaces did: live, neutral and earth from the existing cable. Its small USB input exists only to set it up, which is why the pro joins it to the eufy app on a table indoors and checks the live view before it goes anywhere near a ladder. eufy lists three ways to mount it, on a wall, on a junction box or on a ceiling, and its guide shows an overhang mount, so the underside of a porch roof or a deep eave can take it as well as a flat brick wall.
Nothing in the box encloses the connections. eufy's user guide lists the bracket, screws, a set-up cable and, in some packs, an installation hook, but no junction box, and its FAQ asks for a 'UL-listed' box, which is North American wording rather than a UK rule. Some London outside lights are a bulkhead screwed over a cable that comes straight out of the brickwork. Where there is no sound weatherproof enclosure behind the old light, the pro agrees one with you and adds it at cost before you book.
At 1.38 kg, with twin light panels and a camera that pans and tilts, the E340 needs fixings that bite into sound masonry or timber, not render that has come away from the wall. eufy lists the light as dimmable, which matters on a terraced street where the windows opposite catch whatever it throws.
What the pro checks first
- An earth at the old light, proved with a tester, because eufy says 'Properly ground fixture' and some older London lighting circuits have no earth at all
- What switches the light now: a wall switch, a PIR sensor, a photocell, a timer or a dimmer
- The colours in the existing cable, since eufy's diagram uses North American colours and older UK wiring can be red and black rather than brown and blue
- Whether the circuit has RCD protection at the consumer unit, and is in good enough condition to take the new fitting
- The Wi-Fi reading at the light on 2.4 and 5 GHz, taken while the old fitting is still up
- What sits behind the old light: a sound weatherproof box, or bare cable in the wall
What the pro does on the Floodlight Camera E340
- E340 joined to the eufy app on its set-up USB cable, with the live view confirmed before the old light comes down
- Circuit switched off at the consumer unit and proved dead; the wall switch alone is never trusted
- Existing cable connected brown to live, blue to neutral and green-and-yellow to earth, translating eufy's North American diagram
- Any PIR, timer or dimmer taken out of the supply, so the light and both cameras always have power
- Fitting sealed against rain and the circuit tested, then a Minor Electrical Installation Works Certificate written up for you
- Recording set up on a microSD card or your HomeBase S380, with motion zones and brightness chosen with you
- For a first-floor wall or a high eave, your pro can ask another pro on JACK to help through the Pro2Pro feature
How the Floodlight Camera E340 installation goes
- 1Your photos of the light, its switch and the consumer unit reviewed, so the earth, switching and height are known before the visit
- 2The E340 powered on USB indoors, added to the eufy app and its live view checked
- 3Power off at the consumer unit, the circuit proved dead and the old light taken down
- 4Earth tested and the cable inspected; with no working earth the E340 does not go up, and the remedial options are explained
- 5Bracket fixed over the supply on the wall, junction box or ceiling, inside an outdoor enclosure where one was agreed
- 6Live, neutral and earth connected while the fitting hangs from its strap or hook, then the base snapped onto the bracket and screwed home
- 7Power restored, the circuit tested and the certificate completed
- 8Light, cameras, tracking and storage set in the app, then a walk-past test
Before you book: what to send
- Two photos of the outside light on the wall now: one close enough to read any label, one from the ground that shows its height
- A photo of whatever turns it on: a switch indoors, a PIR sensor, a photocell or a timer
- A photo of the consumer unit with its cover shut and the circuit labels readable
- Whether recordings will go to a microSD card (up to 128 GB, bought separately) or to a HomeBase S380
- In a rented or leasehold home, the landlord's or freeholder's agreement to change an outside fitting
Is eufy's 'licensed electrician' line a legal requirement in London?
No. It is eufy's own condition for every market outside North America. In England the rules work differently:
- There is no electrician's licence to hold in England. The Planning Portal says the building regulations 'do not restrict who may carry out electrical installation work'
- Part P controls which jobs must be notified: a new circuit, a new or replacement consumer unit, or work around a bath or shower. The IET's Part P answers say a light fitted outside is not notifiable when it is connected to an existing circuit, which is what swapping your outside light for the E340 does
- If you would rather meet eufy's wording with an electrician registered with a Part P competent person scheme, book one directly: no pro JACK books is scheme-registered. If the warranty matters to you, ask eufy UK support how it treats an E340 fitted by someone else
Whoever fits it, the work must be safe and tested to BS 7671, and the Minor Electrical Installation Works Certificate is the record that it was.
Do you need an electrician to install eufy? Each kind of device comparedHow do eufy's E340 instructions translate to an English home?
The user guide and FAQ on eufy's UK page are written in North American terms. This is how each line reads in a house or flat in London.
| eufy's instruction | What it means here |
|---|---|
| 'requires hardwired installation with AC 100V – 240V' | Connected to the existing outside-light cable on the same circuit; there is no plug-in version |
| 'UL-listed junction box' | North American wording. In the UK the connections need a suitable weatherproof enclosure and the work follows BS 7671; one is agreed and added at cost if your light has none |
| 'Do not use a dimmer switch or timer for this product' | A PIR sensor, timer or dimmer comes out of the circuit, and any wall switch is left on |
| 'Properly ground fixture' | The earth is proved by test; a lighting circuit with no earth needs remedial work before the E340 goes up |
| Mount at 2.44 m for detection up to 12 m | Usually close to where the old light is, because that is where the supply comes out of the wall |
| 'installation and wiring must be performed by a licensed electrician' outside North America | No such licence exists here. In England, replacing an outside light on its existing circuit is not notifiable under Part P, and the pro leaves a Minor Electrical Installation Works Certificate |
A wall with no outside light and no supply may need a brand-new circuit from the consumer unit, which is notifiable and needs a registered electrician; JACK does not book that as part of this job. JACK does not sell the E340: you buy it, and the pro fits it.
How eufy installation is priced
A vetted pro prices your job from the eufy model, photos of where each device goes and what power is there now, and the JACK app shows you that fixed price before you book.
Full pricing guide for eufy installationFrequently asked questions
Can the eufy Floodlight Camera E340 plug into a socket instead?
No. eufy lists only hardwired mains power at 100–240 V AC, and the 5 V/1 A USB input is marked for set-up only. If there is no outside light to replace, send photos of the wall and of your consumer unit; a job that needs a new circuit goes to a registered electrician, which JACK does not book.
Does the Floodlight Camera E340 need a HomeBase?
No. It records 24/7 to a microSD card of up to 128 GB, bought separately, which eufy says holds about six days of continuous recording at the highest resolution. A HomeBase S380 on firmware V3.3.2.6 or later is the other option, and the pro adds the E340 to yours if you already have one.
Is the Floodlight Camera E340 the same as the Video Doorbell E340?
No, they only share a name. The floodlight is model T8425, a mains light fitting with two cameras; the Video Doorbell E340 is model T8214, a battery doorbell that can also run on bell wiring. Check the model number on the box before you book.
Does the E340 floodlight work with Apple Home or Google Home?
No. eufy's UK FAQ says it does not support HomeKit, and that Google Home is not supported either. It works with Alexa and Google Assistant smart displays, and the light, cameras and recording are all set up in the eufy Security app.
How much does eufy Floodlight Camera E340 installation cost in London?
It is a fixed price for your Floodlight Camera E340, worked out by a vetted pro from the model, a photo of where it is going and what power is there now, and shown in the JACK app before you book. Other devices can go on the same booking for one price. If you would rather pay for time, hourly hire for electrical work is typically £55–£110 per hour as a guide.
