Product Overview
SKU TD-9585S4-PA is an 8MP dual-illumination, weatherproof turret network camera designed for fixed-position surveillance where high-resolution daytime and night-time performance is required. The camera combines a high-resolution 8MP (3840 × 2160) sensor with both infrared and white-light supplement illumination to deliver usable images in low-light and no-light conditions, while built-in audio, local microSD storage and smart detection features help reduce the need for constant human monitoring. IP66 ingress protection and PoE/DC12V power options make it simple to install indoors or outdoors.
Why Choose the TD-9585S4-PA
The TD-9585S4-PA is suitable where clear identification and reliable night-time colour information are important. With H.265+/H.265/H.264+ encoding it reduces network and storage load without sacrificing image quality, and the dual-illumination (white light plus IR) gives flexibility to retain colour at night or switch to infrared imaging when required. Smart alarm functions such as line crossing, region intrusion and abandoned/missing object detection reduce false alarms and focus attention where it matters. PoE support, ONVIF compatibility and microSD local recording (up to 256GB) add installation flexibility and resilience.
Key Capabilities
Provides 3840 × 2160 resolution for detailed scene coverage and improved identification at longer ranges.
Built-in white light and infrared extend usable imaging to 30–40 m, with the option of colour night-time images when white light is used.
Supports line crossing, region intrusion, abandoned/missing object detection and other intelligent events to reduce unnecessary alerts and focus on relevant incidents.
IP66 ingress protection and durable turret form make the camera suitable for exposed locations such as building exteriors, car parks and entrances.
Supports DC12V or PoE (IEEE 802.3af) for simplified cabling, plus RJ45 10/100 Base-T network connection with ONVIF support for integration with existing systems.
Up to three streams, mobile app support for iOS and Android, and compatibility with web browsers and NVR/NVMS platforms for remote viewing and recording.
Key Features
- Video compression: H.265+ / H.265 / H.264+ / H.264 / MJPEG — lowers bandwidth and storage requirements while maintaining image quality.
- Max resolution 8MP (3840 × 2160) — provides fine detail for identification and evidence capture.
- Dual illumination with 30–40 m IR and 30–40 m white light — gives choice between covert IR imaging and colour illumination at night.
- 120 dB Wide Dynamic Range (WDR) plus 3D DNR, HLC and BLC — improves image clarity in scenes with strong backlight or contrast.
- Smart alarm types including line crossing, intrusion and abandoned/missing object detection — reduces irrelevant alerts and helps focus operator response.
- Built-in microphone, speaker and user-defined voice import with blue/red light warning — enables two-way audio and visual deterrence.
- Local microSD storage up to 256 GB and dual-system backup — adds resilience if network recording is interrupted.
- PoE (IEEE 802.3af) and DC12V power options — simplifies installations where power access varies.

Lens Information
Fixed lens: Choosing between the 2.8mm and 3.6mm lens
The TD-9585S4-PA is available with 2.8mm or 3.6mm fixed lenses. The 2.8mm lens offers a wider field of view (H: 103°, V: 55°, D: 121°) which is useful for covering wider scenes such as shop floors or building approaches. The 3.6mm lens narrows the field (H: 86°, V: 47°, D: 100°) and increases effective range, making it better for corridors, entrances or scenes where you need more detail at mid-range.
Varifocal: Understanding the motorised 2.8–12mm lens
The motorised 2.8–12mm lens provides remote zoom and flexible framing so installers and integrators can adjust view angle from the camera interface without physically accessing the device. This is useful for commissioning and for later adjustments if the scene changes.
| Setting | Field / DORI example (from datasheet) |
|---|---|
| Wide (2.8mm) | H FoV ~97°, Detect 86 m, Observe 35 m, Recognise 18 m, Identify 9 m |
| Tele (12mm) | H FoV ~34°, Detect 273 m, Observe 109 m, Recognise 55 m, Identify 27 m |
FAQs
- Can I power this camera over Ethernet?
Yes. The TD-9585S4-PA supports PoE (IEEE 802.3af) as well as DC12V, allowing for simplified single-cable installations where a PoE switch or injector is available.
- How far will the night illumination reach?
The datasheet specifies both infrared and white-light supplement ranges of approximately 30–40 m. White light enables colour imaging at night when activated; IR provides black-and-white night vision.
- What local storage options are supported?
The camera has a built-in microSD slot supporting cards up to 256 GB for local recording. It also supports network remote storage and NVR recording.
- Does it support smart alarm features to reduce false alerts?
Yes. The camera offers SMD and intelligent events including line crossing, region intrusion with human/vehicle classification, and abandoned/missing object detection to focus alerts on meaningful motion.
- Can I view the camera remotely on a smartphone?
Yes. The camera supports remote monitoring via iOS and Android apps, P2P connection and is compatible with web browsers and NVMS/NVR systems for remote viewing and management.
- Is the camera suitable for exposed outdoor locations?
Yes. The unit is rated IP66 for ingress protection, which makes it appropriate for installation outdoors where it will face rain and dust; correct mounting and cable sealing are still recommended.
- What image optimisations are included?
Image adjustments include ROI, saturation, brightness, contrast, WDR, image mirror/flip, 3D DNR, HLC and BLC to help tune images for a particular scene.
