Dahua IPC-HFW2441T-AS 4MP IR Fixed-Focal Bullet WizSense Network Camera
When your security setup needs to be smart, reliable, and genuinely useful in the real world — not just impressive on a product page — the Dahua IPC-HFW2441T-AS is the kind of camera that earns its place. It’s a 4MP IR bullet camera built for serious outdoor surveillance, and what makes it stand apart from the generic crowd is its deep learning-powered WizSense intelligence combined with an unusually rich feature set for its class — including built-in mic, audio output, dedicated alarm I/O ports, and an impressive 80-meter IR range that outperforms most cameras in its price bracket.
For businesses, schools, factories, residential complexes, and retail environments across Bangladesh, this camera punches well above its weight. The WizSense AI engine accurately distinguishes humans and vehicles from irrelevant motion — meaning no more midnight alerts because a cat knocked something over near your entrance, and no more sifting through hours of footage to find what you’re actually looking for. When paired with a compatible Dahua Smart NVR, the Smart Search feature lets you pull up all human or vehicle events instantly, turning what used to be a tedious investigation task into something you can do in seconds.
IPC-HFW2441T-AS offers three lens options — 3.6mm, 6mm, and 8mm — making it versatile enough for wide-angle coverage of parking lots and courtyards, medium-range monitoring of corridors and storefronts, or longer-distance surveillance of perimeter gates and building facades. Its all-metal housing with IP67 and optional IK10 ratings means it handles Bangladesh’s monsoons, humidity, and heat without issue. Whether you’re building a new security system from scratch or upgrading specific coverage gaps in an existing one, this camera is a well-rounded, future-ready choice.

Why You Buy Dahua IPC-HFW2441T-AS
- Industry-Leading 80m IR Range with AI That Actually Reduces False Alarms: Most 4MP cameras at this price point offer 30–40 meters of IR coverage. The IPC-HFW2441T-AS doubles that with an 80-meter illumination range — making it genuinely viable for large outdoor areas like factory yards, school compounds, parking lots, and building perimeters in Bangladesh where long-distance coverage is often the biggest challenge. Combined with WizSense SMD Plus intelligence that filters out non-human, non-vehicle motion, you get both coverage and accuracy in a single device.
- Three Lens Options + Alarm I/O — Rare Flexibility in Its Class: Unlike most bullet cameras that ship in one fixed lens configuration, the IPC-HFW2441T-AS is available in 3.6mm, 6mm, and 8mm variants, letting you match the camera precisely to the coverage zone you need. Add to that the dedicated alarm input and output ports — which most entry-level cameras completely omit — and you have a camera that can trigger external sirens, strobe lights, or door locks based on AI detection events, enabling a more integrated and automated security response.
- Built-In Audio I/O with Two-Way Communication for Real-Time Response: A silent security camera can only document a problem. The IPC-HFW2441T-AS includes a built-in microphone, a dedicated audio input (RCA), and a dedicated audio output (RCA) — giving you two-way audio capability when connected to appropriate speakers. For shop owners, school security staff, or building managers in Bangladesh who need to verbally warn an intruder or communicate with someone at a monitored entrance, this is an underrated but genuinely practical feature that eliminates the need for a separate intercom device in many scenarios.
FAQ
Q1: What is the difference between the Dahua IPC-HFW2441T-AS and the IPC-HFW2449M-S-B-PRO?
These two cameras serve different surveillance philosophies. The IPC-HFW2441T-AS uses traditional IR LED technology, producing black-and-white footage in low light but delivering an impressive 80-meter illumination range — making it ideal for large outdoor zones where coverage distance is the priority. It also includes hardware alarm I/O ports (1 in, 1 out) and full RCA audio I/O, which the WizColor model doesn’t offer. The IPC-HFW2449M-S-B-PRO, on the other hand, prioritizes full-color night vision using warm white LEDs but is limited to 50 meters. Choose the HFW2441T-AS when range, alarm integration, and audio communication matter most; choose the HFW2449M-S-B-PRO when color identification at night is your top requirement.
Q2: What is the price of the Dahua IPC-HFW2441T-AS in Bangladesh?
The Dahua IPC-HFW2441T-AS is typically available in Bangladesh at a price range of BDT 5,500 to BDT 7,500 depending on the lens variant, retailer, and warranty terms, with the best pricing found through authorized Dahua distributors in Dhaka’s Elephant Road technology market and trusted online CCTV retailers.
Q3: Does the Dahua IPC-HFW2441T-AS support two-way audio communication?
Yes — and it’s one of the standout features that differentiates this model from most bullet cameras in its class. The camera includes a built-in microphone for audio capture, plus a dedicated RCA audio input for connecting an external microphone and a dedicated RCA audio output for connecting an external speaker. When configured through the DMSS app or DSS management software and paired with an external speaker at the camera location, it enables real-time two-way voice communication — allowing security personnel to speak directly to people within the camera’s coverage zone, whether for warnings, instructions, or general communication.
