Product Overview
The TD-9585S4-C is an 8MP dual-illumination, waterproof turret network camera designed for exterior and interior surveillance where high-resolution detail and reliable night-time performance are required. This model provides 3840 × 2160 resolution, a motorised 2.8–12mm lens for flexible framing, and both IR and white-light supplementary illumination to deliver usable colour detail in low light. Key benefits include efficient H.265+ compression for reduced bandwidth and storage, IP67 ingress protection for weather resistance, and support for PoE for simplified installation.

Why Choose the TD-9585S4-C
The TD-9585S4-C is built for practical reliability and performance. Its motorised 2.8–12mm lens lets installers adjust field of view remotely, reducing site visits and speeding commissioning. Dual illumination (IR and white light) ensures both long-range detection and recognisable colour detail at night. With H.265+ encoding and support for local microSD (up to 256GB) plus network storage, the camera is efficient on bandwidth and storage cost. IP67 sealing and PoE compatibility make the unit straightforward to deploy outdoors or in exposed locations while maintaining stable power and network connectivity.
Key Capabilities
8MP high-resolution imaging
Delivers 3840 × 2160 detail to capture licence plates, faces and scene detail for clearer evidence and investigation.
Motorised varifocal lens (2.8–12mm)
Remote zoom and focus adjustment let you set framing precisely without returning to site, saving time on commissioning and finescale adjustments.
Dual supplementary illumination
Built‑in IR (30–50 m) and white light (30–40 m) provide flexible night-time operation — IR for covert viewing and white light for colour evidence when required.
Efficient video coding
Supports H.265+/H.265/H.264+/H.264 and MJPEG, reducing bandwidth and storage demands without sacrificing image quality.
Smart analytics and alarm
Includes human/vehicle classification (SMD), line crossing and region intrusion, plus abandoned/missing object detection to reduce false alarms and improve event relevance.

- Public spaces where smart analytics reduce false alarms (human/vehicle classification).
- Sites requiring on‑board edge recording plus central NVR integration.
Understanding the Motorised Varifocal Lens
The TD-9585S4-C uses a motorised 2.8–12 mm lens so you can adjust zoom and focus remotely from the client or NVR. This avoids manual lens changes on site and makes it easier to fine‑tune framing after installation.
| Setting |
Effect / Typical Field of View |
| Wide (2.8 mm) |
Horizontal 97.3°, Diagonal 116° — broad scene coverage for general surveillance and situational awareness. |
| Tele (12 mm) |
Horizontal 34°, Diagonal 37° — tighter framing for identification at distance and longer-range detail. |
DORI example (2.8–12 mm): Detect 88 m / 277 m, Observe 35 m / 111 m, Recognise 17 m / 55 m, Identify 8 m / 28 m (W/T).
FAQs
- Can this camera be powered over Ethernet?
Yes. The TD-9585S4-C supports PoE (IEEE 802.3af), enabling data and power over a single network cable when used with a compatible PoE switch or injector.
- Does it work with third‑party NVRs?
The camera supports ONVIF and standard network protocols, so it can be integrated with many third‑party NVRs that support ONVIF. For best compatibility, check your NVR’s ONVIF profile and firmware version.
- What night‑time performance does it offer?
It has both IR and white‑light supplements. IR provides covert monochrome imaging to 30–50 m; the white light provides colour illumination to 30–40 m when active, useful for identification and deterrence.
- How is local recording handled?
There is a built‑in micro SD card slot supporting up to 256 GB for edge recording. The camera also supports network remote storage and ANR to preserve recordings during network interruptions.
- What analytics does the camera provide?
Built‑in analytics include SMD (human/vehicle classification), line crossing and region intrusion detection, abandoned/missing object detection, and various video exception alarms to reduce false positives and highlight relevant events.
- Which browsers and mobile platforms are supported?
The camera supports mainstream web browsers and remote monitoring via TVT NVR/NVMS and iOS/Android apps. Refer to the manufacturer page for specific browser version notes.
- Is the camera weatherproof for outdoor use?
Yes. The unit is rated IP67 for protection against dust and water ingress, making it suitable for exposed outdoor locations when installed according to best practice.
