Selection notes

• DSM/package features require supported software versions and a verified drive/system configuration.
• RAID is not a backup. Confirm drive compatibility, required retention/capacity and a separately tested backup plan.
• Surveillance figures are total system FPS for one codec/resolution profile, not per camera. Manufacturer HTML describes independent continuous RTSP tests on a drive-populated/default-memory system; SRTP for all cameras reduces stated performance to70%. Other workloads/configurations can reduce it further.
• C2 Storage requires a separately eligible paid subscription.
• C2 Surveillance requires a separate paid subscription per additional channel.
• Camera limits are not included-license counts. No local stock, disks, price, delivery, licenses or warranty are confirmed.
