256 cameras. Sixteen drive bays.
1024 Mbps and up to 384TB.
The IVSEC NR6256EXA is IVSEC's largest recorder: up to 256 IP cameras at up to 12MP, 1024 Mbps of incoming bandwidth, sixteen 3.5" bays for up to 384TB with RAID, and four HDMI outputs for a control room.
In one sentence: the IVSEC NR6256EXA is a 256 channel network video recorder for IP cameras up to 12MP, with 1024 Mbps incoming bandwidth, sixteen SATA bays up to 384TB, RAID 0, 1, 5, 6 and 10, and four 4K HDMI outputs.
Recorder only. Drives, switches and cameras are separate.
The NR6256EXA has no PoE ports, so the cameras are powered by PoE switches on the same network. It ships without hard drives; fit up to sixteen 3.5" SATA drives of up to 24TB each.

One recorder for a whole campus.
With 256 channels and 1024 Mbps of camera bandwidth, a single NR6256EXA can take the cameras from several buildings. Sixteen bays and RAID 5, 6 or 10 give long retention that keeps recording through a drive failure, and the four HDMI outputs can each show a different camera wall.

Front panel
Status lights and USB at the front.
Power and drive lights and a front USB port. On the back: four HDMI outputs, e-SATA, audio out, RS485, alarm terminals for 16 inputs and 4 outputs, and the power input with an on/off switch.

The chassis
Internal power supply, low base draw.
The power supply is built in, and the recorder draws 8 W before drives are added. IVSEC lists it at 189 × 460 × 440 mm and 13.7 kg; IVSEC uses the same front photo for the 8 bay NR6648EX, so confirm the height with us if rack space is tight.
How it goes in
From rack to recording.
01
Fit the drives
Fit up to sixteen 3.5" SATA drives of up to 24TB each with the supplied screws. Use matching drives for RAID.

03
Set up storage and screens
Connect up to four HDMI monitors, run the wizard and choose RAID 0, 1, 5, 6 or 10, or use the drives individually.
04
Add cameras and remote view
Add IVSEC X range or ONVIF Profile S, G or T cameras, set the recording schedule, then connect the IVSEC mobile app or the free VMS.

Storage
Surveillance hard drives
Up to sixteen 3.5" SATA drives of up to 24TB. Tell us the camera count and days to keep and we will size the array.
Power
PoE switches
The recorder has no PoE ports. Managed PoE switches power and connect the cameras on each floor or building.
Cameras
IVSEC X range cameras
Plug and play with the recorder's smart search: intrusion, line crossing, face and plate detection.
Backup power
A UPS
Keeps a large RAID array recording through short outages and avoids sudden shutdowns.

Up to 64 cameras? The NR6648EX is enough. Beyond 64, choose the NR6256EXA. Figures from IVSEC's NR6256EXA (3 November 2026) and NR6648EX (October 2026) datasheets.
Common questions
How many cameras can it record?
Up to 256 IP cameras at up to 12MP each, within 1024 Mbps of total incoming camera bandwidth.
How much storage does it take?
Sixteen 3.5" SATA drives of up to 24TB each, 384TB in total. Drives are not included.
Which RAID levels does it support?
RAID 0, 1, 5, 6 and 10. RAID 6 keeps recording with two failed drives, at the cost of two drives of capacity.
Does it have PoE ports?
No. Power the cameras from PoE switches on the same network as the recorder.
How many network ports does it have?
IVSEC's datasheet lists two non-PoE network ports in one row and one gigabit RJ45 in its connector list. Confirm with us if you need two separate networks.
How many monitors can it drive?
Four, from four HDMI outputs, with up to 64 cameras on each screen and output up to 4K.
Which cameras work with it?
IVSEC X range cameras plug and play, and other brands work over ONVIF Profile S, G and T with firmware 21.12 or later.
Does it do face and number plate search?
Yes, with cameras that support it. Face recognition, licence plate recognition, crowd density and queue length depend on the camera.
How big is it?
IVSEC lists 189 × 460 × 440 mm and 13.7 kg. Rack ears are not listed in the box, so plan on a rack shelf.
Can I view it on my phone?
Yes. Scan the recorder's QR code with the IVSEC mobile app, or use the free Surveillance Client on a PC.
What is the difference from the NR6648EX?
Four times the channels (256 against 64), 1024 Mbps instead of 640, sixteen bays instead of eight, more alarm I/O, USB 3.0 and an internal power supply.
What warranty does it have?
Two years parts, per IVSEC's datasheet. InFront Technologies handles warranty and technical support in Australia on 1300 736 970.
Supported by InFront Technologies.

Installation and safety
Power. The recorder has an internal mains power supply. A new power point or rack power needs a licensed electrician.
Lifting. It weighs 13.7 kg before drives. Lift it with two people when mounting it on a rack shelf.
Cabling. Concealed data cabling to cameras is customer cabling under AS/CA S009 and needs an ACMA-registered cabler.
Privacy. Recording people is covered by state and territory surveillance laws. Point cameras at your own property and put up signage.
What it does not do. No PoE ports and no hard drives included. RAID is not a backup: keep copies of important footage.
