eufy Video Doorbell Installation in London

• S220 and C210: eufy's UK blog of 26 October 2026 says the C210 has left its store, while firmware and app support carry on
• Older wired doorbells such as the 2K Wired and 2K Pro Wired, which need 16–24 VAC at 30 VA and keep their video on the doorbell

• On the rail inside the consumer unit, beside the breakers: if it is too weak, a stronger one goes in its place on the same supply
• Inside a mains-powered chime, where 230 V comes into the chime box: changing it is mains work, and if the chime is being bypassed a new transformer takes over the same feed
• In its own small box, often near the meter or under the stairs
• Nowhere: a battery or plug-in chime means there is no transformer, so the doorbell runs on its battery or a new supply is added

• E340: eufy's UK blog calls it fully compatible with an existing mechanical chime, with the included jumper wire on the 'Trans' and 'Front' terminals in the chime box and the battery left in
• C31: eufy's UK FAQ says the chime 'will need to be bypassed' for 24/7 recording and pre-roll, and the jumpers come in the box
• S330 battery doorbell: mechanical chimes work, digital ones do not
• S4 Wired: eufy's pages do not say, and it ships with a Chime 2, so the pro plans around that

• Chime 2, listed on eufy's UK store as the Simple Chime: Wi-Fi on 2.4 and 5 GHz, ten tones and up to 80 dB; it does not ring for motion, and only the C30, C31 and E340 can reach it on a different network from the doorbell
• Chime 2 needs eufy app 5.2.10 or later, plus HomeBase S380 3.7.1.6 or HomeBase 2 3.3.9.6h where a HomeBase relays it
• MiniBase Chime: 2.4 GHz, eight tones and a microSD slot of up to 128 GB that stores doorbell video for the E340, C31 and C30

• The Wi-Fi signal at the door, read in the eufy app: the E340, C31 and C30 use 2.4 GHz only, and for the S4 eufy wants 8 Mbps of upload or more, ideally 12
• Height and angle: eufy's guides put the doorbell 1.2 m above the ground, and in a deep porch or brick reveal the 15° wedge turns it clear of side walls, which bounce infrared back and blur night video
• The fixing: brick takes plugs drilled through eufy's positioning card, while a narrow uPVC frame may mean mounting on the wall beside it
• The door: in a block, a flat's front door is usually a fire door, so no cable goes through it without the building's agreement

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.
