Why it’s a Good Choice

• Great for upgrading analog systems: If you already have analog/coaxial cameras and plan to migrate to IP later, this hybrid system gives flexibility.

• Cost‑effective for 16 channels: Instead of fully replacing with IP‑only systems, you can leverage existing cameras and add IP later.

• Efficient storage: With H.265+ support and smart compression, you can record more days with fewer storage demands.

• Business‑ready: Supports multi‑user remote access (e.g., via mobile apps), making it suitable for retail, office, or multi‑site installations.

What to Check / Consider Before Purchase

• Hard Drive Capacity & Retention: The unit supports only one SATA drive (check if yours supports more in your region) so if you have many high‑res cameras or long retention requirements you’ll need a large capacity drive.

• Incoming Bandwidth / IP Channels: If you will use many IP cameras at high resolution, verify the max IP channel support and incoming bandwidth (some versions support 64 Mbps incoming).

• Smart Features Limitations: If you want advanced analytics (face recognition, ANPR etc) check whether your camera models support those. Some analytics functions may be disabled if IP extension mode is used.

• Format Compatibility: Even though it supports many analog/coax standards, check that your existing cameras (or planned ones) match the formats (HDCVI/AHD/TVI etc).

• Firmware & Security: As with any networked surveillance equipment, ensure firmware is up to date and remote access is secured. Some users report external login attempts on Dahua devices when ports are left open.
