IVSEC Advanced Deterrent · IVK-51B
Four 8MP cameras that see, warn and record.
One 8-channel recorder, 4TB fitted.
A complete 4K (8MP) IP CCTV kit: four IVSEC NC323ADX turret cameras with AI detection, full-colour night vision, red and blue strobes, a siren and two-way talk, plus an NR308XD 8-channel PoE recorder with a 4TB surveillance drive already installed.
In one sentence: a ready-to-install 8MP security system that spots people and vehicles, warns them off with lights and a siren, and records it all on a 4TB recorder with room for four more cameras.
Everything for a four-camera system
Each camera runs on one network cable back to the recorder, which powers it over PoE. Four of the eight PoE ports are free, so you can add up to four more IVSEC cameras later. Need more recording time? Choose the 6TB or 8TB drive option when you order.

Professional AI cameras, without the guesswork.
The cameras, recorder and drive are matched and tested together, so the system comes up as one: plug the cameras into the recorder, connect a screen and the app, and set your detection zones. Firmware and app servers are hosted in Australia, and the kit is backed by IVSEC’s 3-year warranty, handled locally through InFront.
Why people buy it
Why people choose the IVK-51B.
It warns people off, not just records them
When a person or vehicle crosses a zone you set, the cameras can flash red and blue strobes, sound the siren or play a voice warning, so most intruders leave before anything happens.
Colour footage at night
An F1.0 lens and Sony Starvis sensor keep colour in low light, and the warm-white light switches on when needed, so you can see the colour of a jacket or a car at 2am.
Fewer false alerts
On-camera AI tells people and vehicles apart from moving trees, shadows and animals, so your phone only buzzes when it matters.
Find footage in seconds
Search the recordings for people, vehicles or faces instead of scrolling through hours of video, then export just the clip you need.
Room to grow
Eight PoE channels with four cameras means four free ports for later, and the recorder handles cameras up to 12MP.
Australian support
Australian-hosted app and firmware servers, local technical support, and a 3-year warranty handled in Australia.
Active deterrence
Someone walks in. The lights and siren go off.
Set a zone over the driveway, gate or back door. When the AI detects a person or vehicle there, the camera can flash its red and blue strobes, sound the siren or play a custom voice message, on a schedule you choose. You can also trigger them yourself, or talk to the visitor, from the app.
Full-colour night vision
Colour at night, not grey shapes.
The 1/2.8" 8MP Sony Starvis sensor and F1.0 lens hold colour down to very low light. When it gets darker, the warm-white light gives full-colour video, and smart infrared reaches up to 25 m when you prefer black and white.
AI on every camera
Alerts for people and cars, not leaves.
Human and vehicle detection, line crossing, perimeter intrusion and face capture run on each camera. Build a face list with “allow” and “block” groups for shops, clubs and offices, and get a push alert on your phone the moment a rule is triggered.
How it goes in
From the box to recording in four steps.
01
Plan the views
Pick spots about 2.5–3 m high covering doors, the driveway and side paths. The 2.8 mm lens gives a wide 106° view.
02
Run the cables
Run one network cable from each camera back to the recorder. PoE carries power and video, so no power point is needed at the camera.
03
Plug in the recorder
Connect the cameras to the PoE ports, the recorder to your router and a screen over HDMI. The 4TB drive is already installed.
04
Set up the app
Scan the code in the free IVSEC X app (no account needed), then set detection zones, deterrence and alerts.

Common questions
What comes in the IVK-51B kit?
Four IVSEC NC323ADX 8MP turret cameras, an NR308XD 8-channel PoE recorder with a 4TB surveillance drive installed, and the recorder’s power supply, mouse and HDMI cable. Network cables to the cameras are not included.
Is the hard drive already installed?
Yes. The 4TB surveillance drive is fitted and ready to record. You can choose a 6TB or 8TB drive instead when you order.
How many days of recording will 4TB give me?
It depends on motion, resolution and settings. As a guide, four 8MP cameras recording on motion with H.265 typically keep a few weeks of footage; continuous recording uses more. Choose the 6TB or 8TB option for longer history.
Can I add more cameras later?
Yes. The recorder has eight PoE channels, so four are free. The NC323ADX in white or black matches the kit cameras, and the recorder supports IP cameras up to 12MP.
Do the cameras need a power point?
No. Each camera is powered over its network cable (PoE) from the recorder, so one cable per camera is all you need.
How does the deterrence work?
When the AI detects a person or vehicle in a zone you set, the camera can flash red and blue strobes, sound the siren or play a voice message. You choose which triggers when, or set it off yourself from the app.
Will I get colour at night?
Yes. The Sony Starvis sensor and F1.0 lens hold colour in low light, and the warm-white light gives full-colour video in darkness. Smart infrared up to 25 m is there if you prefer black and white.
Can I talk through the cameras?
Yes. Each camera has a microphone and speaker, so you can listen and talk to visitors from the IVSEC X app.
Is there a monthly fee?
No. Recordings are stored on the recorder’s drive and the IVSEC X app is free, with no account registration needed.
Where are the app servers?
IVSEC hosts its app and firmware servers in Australia.
Can the cameras go outside?
Yes. The NC323ADX has an IP66 weatherproof turret housing for walls and eaves. The recorder goes indoors.
What warranty do I get?
A 3-year warranty, handled in Australia through InFront Technologies.

Installation and safety
Cabling. In Australia, network cable fixed inside walls or ceilings must be installed by a registered cabler. Plugging ready-made cables between the cameras and the recorder is fine to do yourself.
Working at height. Use a stable ladder and have someone with you when mounting cameras under the eaves.
Privacy and audio. Aim cameras at your own property. Recording conversations is covered by state surveillance laws, so check the rules for your state before turning on audio.
