8MP in colour at night.
A 2-pack of the IVSEC NC531ADX.
Two of the IVSEC NC531ADX in one pack, each an 8MP bullet camera with a Sony STARVIS sensor, motorised 2.8–12 mm zoom, colour night vision and red and blue strobes, a siren and two-way talk.
In one sentence: the IVSEC IVNC531ADX-2PK is a pack of two IVNC531ADX cameras, each a wired 8MP (4K) PoE bullet camera with a Sony STARVIS sensor, a motorised 2.8–12 mm lens (107° to 34°), full colour night vision to 25 m, red and blue strobes, a siren and two-way audio, rated IP67 and IK10.
Two cameras. Network cables and recorder are not included.
This pack is two NC531ADX cameras. Each needs its own Cat5e or Cat6 cable back to a PoE port, and a recorder or VMS keeps the footage.
- 2 × NC531ADX camera
- Printed quick user guide (one set per camera)
- Installation template (one set per camera)
- Mounting screws and plugs (one set per camera)
- An IVSEC NVR, or another ONVIF Profile S, G or T recorder
- Cat5e or Cat6 cable for each camera
- Two PoE (802.3af) ports or a switch, or a 12 V DC supply
- IV2422X or IV2477X junction box if you want the cable tail hidden
See them in colour. Then tell them to leave.
At night the warm white light keeps the picture in colour, so you can see what someone is wearing and the colour of their car. When a rule triggers, the camera can flash red and blue and sound its siren, and you can speak to the person through the IVSEC app. IVSEC suggests it for cash registers, shopfronts and entryways.

The camera
2.8–12 mm motorised zoom.
Zoom from a 107° wide view down to 34° from the recorder or app, then let the lens refocus. Small enough for a wall or eave at 84 × 84 × 240 mm and 0.8 kg.

Lights
Warm white, red and blue.
IVSEC rates colour night vision to 25 m from the warm white light. The red and blue lights strobe as a warning, and a built-in microphone and speaker carry the siren and your voice.
How it goes in
From the wall to a warning.
01
Run the cable
Run Cat5e or Cat6 from the camera position to a PoE (802.3af) port on the recorder or a switch. A 12 V DC supply also works.
02
Mount the camera
Mark the holes with the installation template and fix the bracket with the supplied screws and plugs. Add an IV2422X or IV2477X junction box to hide the tail.
03
Add it to the recorder
Find it with IVSEC's Device Search / Config Tool, set a password, then add it to an IVSEC NVR, the IVSEC app (QR code) or any ONVIF recorder.
04
Zoom and set the rules
Zoom the lens to frame the area, draw line crossing or intrusion zones, and choose when the lights, strobe and siren respond.

|---|---|---|
| Cameras | 2 | 1 |
| Camera model | NC531ADX | NC531ADX |

The only difference is quantity: both listings are the same NC531ADX camera from the same IVSEC datasheet.
Common questions
Does it show colour at night?
Yes. The warm white light keeps the picture in colour, and IVSEC rates the night range at 25 m.
What does the deterrence do?
When a rule triggers, the camera can flash its red and blue lights and sound its siren. You can also talk to the person through the IVSEC mobile app.
What is in the pack?
Two NC531ADX cameras, each with a printed quick user guide, installation template and mounting screws and plugs. Cables and a recorder are not included.
How is it powered?
Over the network cable from an 802.3af PoE port or switch, or from a 12 V DC supply. It draws under 14 W.
Can I zoom remotely?
Yes. The motorised 2.8–12 mm lens zooms from 107° down to 34° from the recorder or app, without touching the camera.
What frame rate does it record?
The spec table lists up to 30 fps at 3840 × 2160. IVSEC's overview text says 25 fps, so plan on 25 fps if smooth motion matters.
Does it record sound?
Yes. It has a built-in microphone and speaker. Check your state's surveillance laws before recording audio.
Which analytics does it have?
Face recognition, human and vehicle detection, line crossing, perimeter intrusion, licence plate detection, cross counting, crowd density, queue length, heat map, stationary object and rare sound detection.
Is it weatherproof?
Yes. It is rated IP67 for weather and IK10 for impact, and runs from −35 °C to 60 °C.
How do I hide the cable?
Add IVSEC's IV2422X or IV2477X junction box behind the bracket; both are listed for this camera.
Should I choose the NC531ADX or the NC531XB?
The NC531ADX gives colour at night to 25 m, strobes, a siren and two-way audio. The NC531XB is infrared only but reaches 45 m.
How is the 2-pack different from the single camera?
Only the quantity. Each camera in the pack is the same NC531ADX with the same specifications, mounting parts and 3-year warranty.

Installation and safety
Low-voltage camera. Runs from PoE or 12 V DC, under 14 W. There is no mains wiring. A new power point needs a licensed electrician.
Cabling. Concealed data cabling is customer cabling under AS/CA S009 and needs an ACMA-registered cabler.
Audio, siren and privacy. Recording conversations and filming beyond your boundary are covered by state and territory surveillance laws, and a siren can disturb neighbours. Use signage and set sensible schedules.
What it does not do. No Wi-Fi, no battery and no 4G; it needs a network cable or a 12 V DC supply and a recorder or microSD card to keep video.
