The DH-HAC-HDBW3231E-ZT is a 2MP motorised zoom dome camera designed for demanding surveillance environments. Its Starlight sensor, powerful IR, and 120dB WDR allow clear image capture even in poor lighting. With a rugged IK10 housing and flexible multi-signal output, it’s ideal for upgrades or new installs using existing coaxial cabling.
Key Features
-
Starlight Sensor – Delivers bright, detailed video in ultra-low light environments.
-
120dB True WDR – Captures clear images in challenging lighting, balancing bright and dark areas.
-
2.7–12mm Motorised Zoom Lens – Remotely adjust zoom and focus to cover a wide or narrow scene.
-
Smart IR with 50m Range – Adjusts IR strength automatically to prevent overexposure on nearby objects.
-
Tri-Signal Output – Supports HDCVI, CVBS, and SDI for flexible integrations and testing.
-
IK10 Vandal Resistant – Rugged metal dome can handle impacts and tampering attempts.
-
Audio & Alarm Interfaces – Includes inputs for microphones and external sensors/devices.
-
IP67 Weatherproof – Designed for tough outdoor or indoor environments.
Perfect For:
- Commercial building entrances
- Retail storefronts
- Public car parks
- Council infrastructure
- Warehouse loading bays
- Schools and educational campuses
Install Tips
- Use 2.7mm wide angle for entrances, or zoom in for narrow corridors or gates.
- Ideal for retrofits: reuses existing coax cabling and integrates with legacy DVRs.
- Connect audio-in to capture ambient sound — pair with a compatible DVR for playback.
- Use CVBS/SDI outputs for test monitors or secondary viewing.
- Use weatherproof junction boxes (e.g. PFA138) to protect cables in outdoor setups.
- Enable Smart IR via OSD to prevent wash-out when subjects move close to the dome.

Extra Info
Starlight Low-Light Performance
This camera uses a highly sensitive CMOS sensor to deliver colour video in near darkness (0.005Lux). Even when IR switches on, image clarity and subject detail remain high thanks to intelligent exposure management.
120dB True WDR
Handles challenging lighting, such as backlit doorways or windows. True WDR balances bright and shadowed regions in a single frame — helping avoid blown-out highlights or loss of shadow detail.
Motorised Varifocal Lens
With remote zoom (2.7–12mm), installers can easily frame the scene post-install, reducing time on ladders or adjusting manual focus. Wide settings are ideal for large areas; telephoto settings zoom in for tight coverage.
Robust Outdoor Protection
IP67 weatherproofing and IK10 vandal resistance make this camera ideal for exposed installations. It resists water, dust, and physical impact, reducing downtime from tampering or harsh conditions.
Flexible Video Outputs
This model supports HDCVI, SDI, and CVBS outputs — ideal for projects where you need testing, integration with legacy systems, or a hybrid setup with both digital and analog recording.
Q&A
Does this camera capture colour video at night?
Yes, its Starlight sensor allows colour recording in very low light. When light levels are too low, it switches to B/W with IR.
Can I control the zoom remotely?
Yes, the 2.7–12mm motorised lens allows you to adjust zoom and focus from the DVR or interface.
Does it have deterrent features like lights or a siren?
No, this is not a TIOC model — there are no active deterrents like strobe lights or sirens.
Can this work with my existing coaxial wiring?
Absolutely. It's designed for HDCVI and supports long-range transmission over coax, up to 800m.
Can I hear sound from this camera?
Yes, it has an audio input. You’ll need to connect a compatible microphone and use a DVR that supports audio input.
Is this suitable for high-risk outdoor environments?
Yes, the camera is IK10 vandal resistant and IP67 rated — perfect for exposed or high-traffic areas.
Can I record video with a third-party DVR?
The HDCVI signal works best with Dahua HCVRs, but you can use CVBS or SDI for integration with other brands.
How does this compare to a TIOC camera?
This is focused on image quality and durability — not deterrence. TIOC models offer red/blue lights and sirens for proactive security.
