SureVision 32-Channel 4K NVR with 4TB Storage
Network recording for up to 32 IP cameras.
Record up to 32 compatible IP security cameras with the SureVision SV-NVR432-N. This network video recorder provides 320 Mbps incoming bandwidth, dual Gigabit network connections and four SATA drive bays, with a 4TB surveillance hard drive included.

Built for network-connected cameras
Connect cameras through compatible network and PoE switches. This model does not provide built-in PoE camera ports.
Four drive bays
Add compatible storage as the system grows. RAID 1 and RAID 5 are supported when the required drives are installed and configured.
Multi-camera monitoring
Use 4K HDMI or VGA for local viewing, search supported camera events, and export important recordings.

Storage and recording time
One 4TB drive is included. Four SATA bays allow additional compatible drives for longer retention or a supported redundant RAID configuration. The included drive alone does not provide RAID redundancy. *Observe the published drive and operating requirements.
Local recording and free remote viewing
Record and play back video locally without an internet connection. Use a properly configured internet connection for off-site phone or computer viewing. Standard local recording and supported remote viewing do not require a monthly cloud-storage subscription.
Compatible IP cameras provide the available smart events; features and channel limits depend on the camera, recorder firmware and configuration. Recording resolution and multi-screen decoding are different specifications.
Is this the right recorder for your cameras?
A fit for commercial buildings, warehouses and multi-zone properties. Cameras connect through the network, so size the PoE switches, uplinks and total camera bitrates for the installation. A 24-camera installation leaves eight channels available for future cameras.
Are there 32 built-in PoE ports?
No. The 32 channels are camera recording channels. Use compatible network switches and suitable camera power.
