eufy Installation in London: Doorbells, Cameras, HomeBase and NVR

• Video doorbells: the E340, S4 Wired, C31, C30 and S330 battery doorbell, with the transformer and chime sorted
• Battery and solar cameras: eufyCam S4, S3 Pro, C35 and C37 kits, SoloCams and the 4G LTE Cam S330, fixed high with any solar panel in the sun
• The Floodlight Camera E340, wired to the mains where an outside light is now
• HomeBase S380, HomeBase Mini and HomeBase Professional S1: sited and updated, with a hard drive fitted in the S380 or Pro S1
• PoE systems: the NVR Security System S4 Max, S4 and E50, with cable run through brick, loft or garage
• Indoor and window cameras, Chime 2 and MiniBase Chime, entry and motion sensors, and the Smart Display E10
• Older kit such as eufyCam 2 and 3, the 2K wired doorbells and the Floodlight Cam 2 Pro: moved, re-paired or replaced

• eufy's guidance puts a camera 3–5 m from the HomeBase for the best signal, and says that beyond 15 m the link is likely too weak
• Thick brick, solid wood doors and metal roller doors weaken it; concrete, steel doors and steel beams stop it
• In a terrace the router is often at the front or the back, so a camera at the end of the garden may have the whole house between it and the hub
• The fix is usually placement rather than more kit: the HomeBase moved to the middle of the house on a network cable, or a mesh node halfway

• Many British bell transformers give 8 V at about 8 VA, and they sit in the consumer unit, inside a mains chime or in a box of their own
• To keep an E340 charged, eufy asks for 8–24 V at more than 10 VA, and for 24/7 recording the C31 needs 16–24 V at 30 VA
• The S4 Wired needs 16–24 VAC at 10 VA or more, by eufy's Irish product page, and the older wired doorbells 16–24 VAC at 30 VA
• Some set-ups need the old chime bypassed, such as the C31 in 24/7 mode, so a plug-in Chime 2 or MiniBase Chime takes its place indoors

• A new circuit from the consumer unit; JACK treats a doorbell transformer on a new way in it the same
• A new or replacement consumer unit
• Any addition or alteration near a bath or shower

• Text-only notifications, eufy's default since January 2023, unless you choose thumbnail previews, which eufy says are sent to its cloud
• Video kept on the device or the HomeBase, with eufy's optional cloud backup left off unless you want it
• Two-factor login on your eufy account
• Privacy zones over a neighbour's windows or garden, up to two per camera, and activity zones that leave out the pavement and road
• Each camera aimed at your own property, since GOV.UK says data protection law applies once a camera records people beyond your boundary

• eufy's lock requirements: a door 35–55 mm thick, a 60 or 70 mm backset, a 38–54 mm cross-bore and a 25 mm edge hole, on a wooden door rather than glass or a slider
• A typical London front door is uPVC or composite with a multipoint lock turned by a euro cylinder, or timber with a nightlatch and a mortice deadlock, and neither has a cross-bore
• Drilling a cross-bore through a multipoint door could weaken it

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.

The power and the walls move the price more than the device does. A battery doorbell on a brick reveal, or a SoloCam on a fence post, is a smaller job. An S4 Wired doorbell on a new transformer, a HomeBase moved to the middle of the house with a hard drive fitted, a Floodlight Camera E340 in place of an outside light, or four PoE cameras cabled through solid brick and a loft all take longer, and the price reflects that.

The eufy kit is yours to buy, since JACK sells no devices. A stronger transformer, a Chime 2, a wedge, a floodlight's weatherproof box or extra Cat cable is agreed with you and added at cost before you book, and several devices go on one booking for one price. Where parking has to be paid for, that is added at cost and agreed before you book too.

Prefer to pay for time? As a guide, smart home work is typically £45–£95 per hour, and electrical work such as a floodlight camera £55–£110 per hour. For a multi-camera system or a PoE NVR, a full-day booking is a flat £350–£400 for up to 8 hours on site.
