Accepting a single bundled price
One lump-sum number hides where the margin sits — often a meaningful hardware markup on a single device. Insist on separate lines for device, labour, electrical work and network work. Vendors who quote in lines are also, reliably, the ones who have thought the job through.
Skipping the wifi survey
Concrete UAE walls kill more smart home projects than any hardware fault. A device installed at the edge of coverage works during the demo and drops offline the first weekend. Get signal checked at every device location before finalising the plan, and treat network spend as the foundation, not an optional extra.
Ignoring running costs at purchase time
Camera cloud subscriptions, hub-locked ecosystems and battery replacement schedules are the quiet second invoice. Over three years, subscriptions on a few cameras can outgrow the original install bill. Favour local storage where it fits your needs, and standardise on one ecosystem before the third device, not after the tenth.
