Home security in Bangladesh usually means a guard, a padlock and hope. These three products cover the gap for a flat or a small shop, and none of them requires wiring, drilling into concrete, or an electrician.
The WOFEA WG15 is the hub: a smart alarm system that works over both WiFi and GSM through the Tuya app. The GSM half matters here — when your broadband drops or the power goes, a WiFi-only alarm goes silent, while this one still reaches your phone over the mobile network. The PST-IR200B is a wireless PIR motion sensor for a hallway, stairwell or shop floor: it detects body heat moving through a space rather than simply light changing, so a passing shadow will not set it off. The PST-DS100B is a wireless door and window magnetic sensor — two small pieces, one on the frame and one on the door, that report the moment they separate.
The sensible way to start is one hub plus a door sensor on your main entrance, then add motion sensors for the rooms that matter. You do not need to cover the whole property to get the alert that counts.
All three ship cash on delivery, and delivery is free above ৳4,000 — a hub plus two sensors will usually get you there.
All three carry a 6-month warranty, and you have 7 days from delivery to ask for a replacement or a refund. If a unit arrives defective, damaged or wrong, we pay the return shipping and you choose between a replacement and a full refund. Delivery runs 1–2 working days inside Dhaka and 2–4 outside it, to every district in Bangladesh.
Both sensors arrive ready to mount: the PIR motion sensor ships with its batteries, a bracket, screws and wall plugs, and the door sensor with its adhesive pad and battery. Neither needs a drill or an electrician.
