Aqara Video Doorbell and Camera Installation in London

• Doorbell Camera Hub G410 (CH-C09): six AA batteries, up to 5 months, or a wired 12–24 V AC or DC supply; continuous recording and RTSP streaming work only when it is wired
• Doorbell Camera G400 (DB-C03): wired only, at 8–24 V AC or DC, or Power over Ethernet (IEEE 802.3af); Aqara recommends 12 V at 12 VA or more, 16 V at 16 VA, 18 V at 18 VA or 24 V at 12 VA, and marks 8–10 V 'not recommended'
• Video Doorbell G4: a six-AA pack, up to 4 months, or wired at 12–24 V AC or 8–24 V DC; it joins 2.4 GHz Wi-Fi only, and Aqara suggests a porch or shaded spot
• Many British bell transformers give only 8 V, below the G410's and G4's AC minimum, so the routes are batteries, the third-party 12 V DC plug-in supply the Aqara UK Shop sells for both, or a new transformer on a fused spur

• The G400's page says it does not work with your existing traditional chime, and a plug-in chime comes in the box
• The G410's indoor chime runs from USB-C at 5 V, and Aqara's spec sheet lists it as the chime and hub in one
• The G4's chime-repeater, also on USB-C, rings at up to 95 dB and extends the doorbell's connection
• To keep an old bell ringing, Aqara's forum staff describe adding a Dual Relay Module T2, which means mains work at the relay; most installs use Aqara's chime instead

• Camera Hub G5 Pro, outdoors, in PoE (CH-C03) or Wi-Fi (CH-C07) versions: 2688 × 1520 video, USB-C at 5 V 2 A or PoE at 48 V, rated −30 to +50 °C, and a Zigbee and Thread hub too
• For the PoE version, Aqara's Amazon UK listing says a PoE switch is required and sold separately, so the pro runs one data cable from it to the camera, with no mains work at the wall
• Camera G100, indoors or out: it needs a 5 V 1 A adapter that is not in the box and joins 2.4 GHz Wi-Fi only, so outdoors the job is a sealed cable route to an indoor socket
• Indoor cameras: the pan-tilt Camera Hub G3 with its built-in infrared controller, the Camera Hub G350, which Aqara bills as the first Matter-certified camera, and the Camera E1

• GOV.UK's domestic CCTV guidance says data protection law applies once a camera captures people beyond your property, so the pro angles it at your own door and path and sets privacy masking on the G410
• Face recognition on the G4 and G410 is best kept to your own household, and audio left off unless you need it
• On a flat's entrance fire door nothing is drilled through the leaf or frame; a battery G410 on the wall beside the door, with the managing agent's agreement, is the usual route
• On a listed building, works that affect its character need listed building consent, so check with the council before a camera is fixed to the old fabric

A vetted pro prices your Aqara job from the models and your photos, and the JACK app shows that fixed price before you book.

What the job touches moves the price more than the device does. Pairing a hub, fixing sensors, clipping a Curtain Driver E1 onto a rail or fitting radiator thermostat heads is set-up work. A smart lock is locksmith work on the door. An H1 or H2 switch, a Dual Relay Module T2 or a 230 V blind motor is mains work on an existing circuit, priced for isolating, connecting and testing.

The home comes next: a multipoint door that needs adjusting before a lock goes on, a bell transformer too weak for the doorbell, a PoE cable through solid brick. Where a job needs a second pair of hands, your pro can ask another pro on JACK to help through the Pro2Pro feature. Several devices, Aqara or other brands, go on one booking for one fixed price.

You buy the Aqara products; JACK does not sell them. Accessories the job needs, such as a replacement cylinder, a deeper back box, a 12 V plug-in supply or a PoE injector, are agreed and added at cost before you book, and so is parking where it has to be paid for. Prefer to pay for time? As a guide, hourly hire is typically £45–£95 per hour for smart home work, £55–£110 for electrical work and £60–£130 for locksmith work, and a full-day handyman booking is a flat £350–£400 for up to 8 hours on site.
