In one sentence: the IVSEC NR6644EX is a 64 channel network video recorder for IP cameras up to 12MP, with 640 Mbps incoming bandwidth, four SATA bays up to 96TB, two gigabit network ports and four HDMI outputs.
Recorder only. Drives, PoE switch and cameras are separate.
The NR6644EX has no PoE ports, so the cameras are powered by a PoE switch on the same network. It ships without hard drives; fit up to four 3.5" SATA drives of up to 24TB each.

Room for every camera on a large site.
Sixty-four channels and 640 Mbps leave headroom for a full building of 4K and 12MP cameras. Spread the live view across four HDMI screens, search by smart events from the cameras, and use the second network port to keep the camera network apart from the office LAN.

The connections
Four HDMI, two network ports.
Four HDMI outputs, two gigabit RJ45 ports, e-SATA for external storage, audio out, RS485 for PTZ control, the alarm terminals (8 in and 1 out) and the power input with an on/off switch.

Close-up
One cable per screen.
Each HDMI port can drive its own monitor, with up to 64 cameras on one screen. The USB ports in IVSEC's photo are marked USB 3.0, while the datasheet lists two USB 2.0 ports; confirm with us if USB speed matters to you.

Front panel
Status at a glance.

Common questions
How many cameras can it record?
Up to 64 IP cameras at up to 12MP each, within 640 Mbps of total incoming camera bandwidth.
Does it have PoE ports?
No. It has two gigabit network ports and no PoE. Power the cameras from a PoE switch on the same network.
Are hard drives included?
No. It takes up to four 3.5" SATA drives of up to 24TB each, 96TB in total. We can supply surveillance drives with it.
Does it support RAID?
No. IVSEC lists RAID as not available on the NR6644EX. The NR6648EX supports RAID 0, 1, 5, 6 and 10.
How many monitors can it drive?
Four, from four HDMI outputs, with up to 64 cameras on one screen.
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, human and vehicle detection and line crossing depend on the camera.
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 are the two network ports for?
Both are gigabit RJ45 ports. A common setup is cameras on one and the office network on the other; confirm the network mode for your site with us.
Can it fit in a rack?
The case is 326 mm wide and 66 mm high. Rack ears are not listed in the box, so plan on a rack shelf.
What power does it use?
8 W without drives, from the supplied external power supply. Add the draw of each drive you fit.
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.
Help sizing drives, switches and cameras for a large site: call 1300 736 970 or email [email protected]. The datasheet is on the Attachments tab.
Installation and safety
Power. The recorder runs from its supplied power supply. A new power point needs a licensed electrician.
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, no RAID, and no hard drives included.
