Special Series · 4 MP · Anti-Ligature Corner Mount · IK10 +50 JDahua 4 MP Anti-Ligature Corner CamDahua DH-IPC-HCBW8442P-0250B — 4 MP Pro AI Anti-Ligature Corner-Mount Vandal Camera (Special Series, 2.5 mm)
The Dahua DH-IPC-HCBW8442P-0250B is a Special Series 4 MP corner-mount anti-ligature camera — engineered for the specific compliance challenges of custodial, mental health and youth detention facilities where standard ceiling and wall cameras present ligature and tamper risks. The wedge-shaped chassis mounts flush into a wall-ceiling corner with no protruding components, hinges or ligature points. Built around a 1/1.8" CMOS capturing 2688 × 1520 at 25/30 fps with triple-stream H.265 + H.264 encoding. The 2.5 mm fixed lens with distortion correction delivers a wide corner-fill field of view; built-in IR reaches up to 10 m for the close-range room coverage typical of cells, interview rooms and holding areas; WDR is 140 dB. The metal housing is rated IK10 +50 J impact — one of the highest-rated impact ratings in any commercial CCTV camera — and IP67 sealed. Onboard Pro AI features include perimeter protection, SMD Plus and abnormality detection. ePoE supports long-distance PoE runs on Cat6. Built for Australian custodial, mental health, secure aged-care, youth justice and police custody applications. Backed by a 5-year Australian warranty through CCTV Guru.
Why Choose the Dahua HCBW8442P Anti-Ligature Corner Camera
Anti-Ligature Corner-Mount Design
Wedge-shaped chassis sits flush in the wall-ceiling corner with no protruding edges, hinges or ligature points. Designed specifically for cells, interview rooms, seclusion rooms and other high-risk environments.
IK10 +50 J Impact — Beyond Standard Vandal
50-joule impact rating — significantly higher than the 20 J of standard IK10 cameras. Built for environments where occupants may attempt to damage the camera.
1/1.8" Sensor & 140 dB WDR
Large 1/1.8" CMOS with true 140 dB WDR — clear image in cells with strong fluorescent overhead lighting and shaded floor zones in one frame.
2.5 mm Wide Corner Fill
Wide-angle 2.5 mm lens with optical distortion correction. Designed to cover the full room from a corner position with minimal blind spots.
Triple-Stream H.265 + H.264
Triple-stream encoding for simultaneous full-quality recording, mobile streaming and analytics processing.
Audio + Alarm I/O for Duress Integration
1 in / 1 out audio for talk-back; 1 in / 1 out alarm wet-contact for integration with duress alarms, door sensors and nurse-call systems.
Important Install Note
This is a corner-mount camera — the chassis is purpose-built to fit a 90° wall-ceiling corner. Standard wall- or ceiling-mount brackets are not used. Confirm with your facility design and engineering team that the install corner geometry is suitable. Audio recording in custodial and health-care environments is subject to specific privacy and Mental Health Act requirements — ensure local compliance before enabling.

Typical Applications
Custodial Facilities
Cells, interview rooms, holding areas, exercise yards and visit rooms in adult and youth correctional facilities.
Mental Health Inpatient
Seclusion rooms, observation rooms, secure wards — where ligature risk requires anti-ligature hardware.
Police Custody
Holding cells, interview rooms and watch-house facilities.
Secure Aged Care & Dementia
Locked dementia units and high-dependency wings where occupant safety is paramount.

Frequently Asked Questions
What is "anti-ligature"?
Anti-ligature equipment is designed without protrusions, sharp edges or hardware that can be used as a tie point. Required in custodial, mental health and youth detention environments to reduce self-harm risk.
What does "IK10 +50 J" mean?
Standard IK10 cameras withstand 20 J of impact (5 kg dropped 40 cm). This camera withstands 50 J — over 2.5× more impact energy. Designed for environments where direct, repeated impact is expected.
How do I mount it?
The chassis is shaped to sit flush in the corner of a wall and ceiling at 90°. Standard wall and ceiling brackets are not used — the camera mounts directly to the corner.
How far does it see at night?
Up to 10 m built-in IR — designed for the close-range coverage required in cells and interview rooms.
Does it have audio?
Yes — 1 in / 1 out audio I/O for talk-back. Audio recording in custodial and health-care environments is subject to local compliance — check before enabling.
Does it work with third-party VMS?
Yes — ONVIF Profile S, G, T.
What is the warranty?
5-year Australian warranty via CCTV Guru.
What temperature range?
−30 °C to +60 °C.
Can I view it on my phone?
Yes — Dahua's free DMSS app on iOS and Android.
