In a villa, a video doorbell is mostly a power-and-signal problem. The natural position is the gate or the boundary wall, which is often the worst wifi spot on the property and may have no power nearby. A battery model avoids the wiring but adds a recurring chore of recharging every few weeks in summer heat that also shortens battery life. A wired unit is the better long-term answer, but if there is no existing bell wiring to the gate, cabling and a wifi extender push a simple AED 250–400 job toward AED 500–800.

Price accordingly: a straightforward tower doorbell or peephole install is light work and should sit near the bottom of the market range, while a villa install with cabling belongs in the middle. If a vendor quotes villa-complexity money for a tower job, that is a quote worth challenging — comparing two or three vendor ranges side by side in the tamam app makes this kind of mispricing obvious quickly.

Curtain and blind motors carry the widest and least transparent pricing in the smart home market, because the job blends three variables most customers cannot easily benchmark: the motor, the track, and the power. A retrofit motor that drives your existing track is the budget route; a new motorised track cut to size is the premium route; and either may need an electrician to add a concealed power point behind the pelmet, since battery-powered motors trade convenience now for recharging later.

Two questions strip most of the padding out of a curtain quote. First: is the price per window or per track, and what exact track length does it assume. Second: does it include the electrical point, and if not, what is that line item. Vendors who answer both crisply tend to be the ones who have done the job many times.

Cross-vendor comparison is where the real savings live, because pricing discipline in this trade comes from competition, not regulation. The same four-device install can come back with totals differing by AED 400–800 between vendors, usually because one is marking up hardware heavily while another marks up labour. This is exactly the comparison the tamam app is built for: it lists multiple verified vendors against your job with transparent AED price ranges rather than a single fixed rate, and booking, payment and tracking stay in-app, so the quote you compared is the record you hold if anything is disputed later.

Beware the lowball. A quote dramatically under the field usually excludes something — the mesh node your concrete walls will demand, the power point the curtain motor needs, the second visit when the ordered track arrives. Ask the cheapest vendor directly what happens if extra work is discovered on site, and get the answer in writing. The honest ones will tell you; the others just became easy to eliminate.
