NVR-side AI evaluation
32-Camera NVR-side People Detection: Model Variant Comparison
Prepared as a 3rd-party product-evaluation narrative. Scope: normal/non-AI IP cameras, with people detection done by the NVR.
1. Executive Summary
The goal is 32 non-AI-enabled IP cameras, with people detection performed by the NVR Dahua NVR608H-32-XI, which is so far the only model in this shortlist that earns the clean “trusted” badge.
Hikvision DS-7732NXI-I4/S(E) is attractive on price, but level of searchable information had not given a clear indication of its trust level.
The trust level depends on suffix, firmware, and Hikvision-camera compatibility.
Hikvision iDS-9632NXI-I8/S looks powerful on paper, but for this exact 32-channel NVR-side people-detection requirement, it is not the hero model.
2. Model Comparison — which can be trusted for NVR-side people detection?
Details
| Rank | Image | Model | Indicative price | What the spec/story says | Trust level | Buyer-style verdict | Reference |
|---|---|---|---|---|---|---|---|
| 1 |  |
Dahua NVR608H-32-XI | ≈ S$2.5k+ indicative | Officially states 32 access channels and “SMD Plus by Recorder: 32-channel”. | ✅ Trusted | Bandwidth and feature wording both support 32CH NVR-side people filtering. Local decoding with AI enabled is a separate limitation. | source |
| 2 |  |
Hikvision DS-7732NXI-I4/S(E) / DS-7732NXI-I4/S-class | ≈ S$714–S$1.24k indicative | Motion Detection 2.0 by Device/NVR may be all-channel for Hikvision cameras in /S(E)-type sources; suffix and firmware matter. | ⚠️ Questionable / conditional | Price attractive, but do not buy without written confirmation that people detection is by NVR/device, not by camera. | source |
| 3 | |
Hikvision DS-7732NXI-I4/S base/non-E ambiguity | Seller-dependent; varies by region/suffix | Model-name trap: useful evidence may belong to /S(E), while base /S can differ by suffix, region, and firmware. | ⚠️ Questionable | Do not buy by model name alone. Require exact datasheet proof that detection is by NVR/device, not by camera. | source |
| 4 |  |
Hikvision iDS-9632NXI-I8/S | ≈ S$1.1k–S$1.2k indicative | DeepinMind 32-channel input, but source found says Human/Vehicle Analysis up to 16-ch 4MP. | ❌ Not trusted for this requirement | Premium recorder, wrong fit for strict 32 normal cameras with NVR-side people detection. | source |
3a. Detailed Table Contains Below
- Model image column beside each model name.
- Price, feature wording, NVR-side people-detection trust level, bandwidth, degradation, stream-count math, headroom, and verdict in one consolidated table.
- Dahua rows preserve incoming / recording / outgoing because Dahua publishes all three values.
- Hikvision rows use incoming / outgoing where those were found; recording bandwidth was not separately confirmed in the sources used.
- Out* means outgoing network bandwidth only matters when the NVR transmits streams outward to app / VMS / playback / export. It is not camera ingest, recording, or detection itself.
3b. Assumptions:
- 1080p H.265 planning bitrate: 2.5 Mbps per camera.
- 1080p H.264 planning bitrate: 5 Mbps per camera.
- High camera bitrate: 8,192 kbps = 8.192 Mbps per camera.
- 32-camera total bitrate: H.265 = 80 Mbps, H.264 = 160 Mbps, high stream = 262.144 Mbps.
- Network degradation scenarios: 0%, 30%, 40%, 50%.
- Prices are indicative, NVR-only unless seller says otherwise; they may exclude HDD, GST/VAT, shipping, installation, warranty uplift, and local support margin.
