The TVT TD-3332H4-16P-B2 is a high-performance 32 channel NVR suitable for larger residential, commercial, enterprise, warehouse, school, government and industrial CCTV systems. It supports up to 32 IP cameras and is capable of recording cameras up to 16MP resolution, making it a strong choice for sites requiring detailed video capture across many areas.
This model includes 16 built-in PoE ports, allowing up to 16 compatible PoE IP cameras to be connected directly to the NVR without requiring a separate PoE switch for those channels. Additional cameras can be added over the network using external PoE switches where required.
For storage, the NVR features 4 x SATA hard drive bays, with support for up to 10TB per HDD. This provides excellent recording capacity for larger systems, especially where higher camera counts, higher resolution footage or longer retention periods are required.
The TD-3332H4-16P-B2 supports H.265S, H.265+, H.265 and H.264 compression, helping reduce bandwidth and storage usage while maintaining strong image quality. It also supports 320Mbps incoming and 320Mbps outgoing bandwidth, giving it the performance needed for larger IP CCTV systems.
The recorder provides 4K HDMI output, dual HDMI output, VGA output and multi-screen live view options. It also supports up to 16 channel simultaneous playback, making it easier to review footage across multiple cameras at once.
When used with compatible TVT AI cameras, this NVR supports advanced intelligent functions including face detection, face comparison, human and vehicle classification, video metadata, perimeter protection events, licence plate recognition, region intrusion, tripwire detection, object abandoned/missing and other VCA events. This makes the system far more useful than basic motion detection for commercial and security-sensitive environments.

Installer Notes
- This model has 16 built-in PoE ports. For camera counts above 16, use an external PoE switch connected to the network.
- The NVR supports 32 total IP camera channels, but only 16 cameras can be connected directly to the built-in PoE ports.
- Use surveillance-grade HDDs only. Standard desktop hard drives are not recommended for 24/7 CCTV recording.
- AI features depend heavily on the camera model used. For best results, pair with compatible TVT AI cameras.
- Third-party ONVIF cameras may connect, but advanced functions such as AI events, licence plate recognition and smart search may not work across all brands.
- The total PoE budget is 150W. Check camera power requirements carefully when using PTZs, varifocal cameras, heaters or high-power models.
- For long cable runs or remote buildings, use external PoE switches, fibre links or point-to-point network bridges where appropriate.
