Dahua IPC-HDBW2541R-ZAS 5MP dome camera with motorized zoom, microphone, audio and smart detection

5MP dome camera with motorized zoom and smart surveillance

IPC-HDBW2541R-ZAS is a dome camera from Dahua's WizSense series. It's made for installations where you'd like to adjust the framing more precisely than with a fixed lens, while also getting intelligent features that make everyday monitoring easier to manage.

The camera is well suited for entrances, façades, common areas, businesses, storage areas and other locations where you want a camera with zoom capability, night vision and more accurate event detection.

Motorized zoom

The camera has a motorized lens from 2.7 to 13.5 mm. That means you can adjust the field of view directly from the system without having to be physically at the camera to change the lens.

That makes installation more flexible, because you can start with a wide view and then fine-tune the image so it fits the area better. For example, you can choose more overview at an entrance or zoom in on a gate, a door or a specific spot.

5MP resolution

With 5 megapixels you get an image with more detail than standard 2MP surveillance. This gives you a better starting point when you later review recordings and assess what happened.

The camera also supports 4MP at 25 or 30 frames per second if you prefer a smoother frame rate. That gives you flexibility depending on what suits your installation best.

IR night illumination

The camera has built-in IR illumination with a range of up to 40 meters. That makes it possible to monitor the area even when it's dark. The IR light is invisible to the human eye but allows the camera to produce a clear night image.

This means you can still get useful recordings at night, even if there's no regular lighting in the area.

People and vehicle detection

The camera supports perimeter functions like line crossing and intrusion, and it can distinguish between people and vehicles. That makes it easier for you to focus on the events that matter.

In practice this means fewer unnecessary alarms from things you're not interested in, and a more manageable event list in the system.

SMD Plus

SMD Plus is Dahua's smart motion detection. The feature analyzes movement in the image and helps filter out less relevant events so you don't waste time on ordinary motion.

It makes monitoring more useful day-to-day, especially in areas where there can otherwise be a lot of movement from the surroundings.

Perimeter protection

Perimeter protection lets you set up rules like line crossing and intrusion for a specific zone. It's useful if you want to keep a closer eye on certain areas, for example at a gate, driveway or access point.

When a rule is broken, the camera can detect the event more precisely and forward it to a recorder or app.

Wide Dynamic Range

The camera has 120 dB WDR, which helps balance bright and dark areas in the same image. This is especially useful at entrances, windows and façades where lighting can vary a lot.

That makes it easier to see both what's happening in the shadows and in the bright areas without the image becoming too dark or blown out.

Built-in microphone, audio in and out

The ZAS version supports audio and has audio in and out. This lets you record sound together with video and connect additional audio equipment if the installation requires it.
It can be useful in setups where audio provides extra information about an event, or where you want more flexibility around connected equipment.

Alarm input and output

The ZAS version also has alarm input and output. That means the camera can work with other security equipment, such as a sensor, an external alarm or other relay-controlled devices.
It gives you more options if the camera should be part of a larger solution.

SD card recording

The camera supports microSD cards up to 256 GB. This allows you to store recordings directly on the camera, either as local storage or as extra protection if the connection to the recorder is interrupted.

That can be an advantage in both small and large installations where you want more flexibility.

PoE power over network cable

The camera supports PoE so you can run both power and network over the same cable. That simplifies installation and can save time during mounting.
It's especially useful if the camera is mounted where you want to avoid an extra power supply near the camera.

IP67 and IK10

The camera is IP67 rated, which means it's protected against dust and rain. It can therefore be used both indoors and outdoors when mounted correctly.
It also has an IK10 rating, which means the housing has high resistance to impact. That makes the model suitable for locations where the camera is exposed.

Cybersecurity

Dahua has built several security features into the camera, including encryption, access control and secure boot. That helps protect the camera and your data from unwanted access.
It's especially relevant when the camera is part of a network and needs to run reliably over time.

Mounting

The camera can be mounted directly on a wall or ceiling. If you want a neater installation or more space for cables and connections, a junction box or a suitable bracket can be a good solution.
You can always check the “accessories” tab for this camera to find the mounts and installation parts that fit this specific model.

Power over Ethernet

Do like the professionals. POE means that only one cable is needed for the camera. The camera gets power through the network cable, typically from a recorder with built-in PoE, or from a POE switch.
