Description TD-9545S4-C(D/AZ/PE/AW3)4MP Dome Dual Illumination Water-proof Turret Network Camera

Video Coding Standards: H.265+ / H.265 / H.264+ / H.264 / MJPEG

• These are video compression formats, much like a ZIP file is for documents.
  • H.265+ and H.265 (HEVC): These are the most modern and efficient standards. They significantly reduce the file size of high-quality video, which saves a great deal of storage space on your hard drive (or memory card) and requires less internet bandwidth for remote viewing.
  • H.264+ and H.264: This is the previous generation of compression, still very popular and widely used. The camera's support for it ensures compatibility with many older recording devices and software.
  • MJPEG: An older format that compresses each frame of video as a separate image. It uses a lot of storage space and is rarely used for primary recording today.

Maximum Resolution: 4MP (2560 × 1440)

• This refers to the image quality and level of detail the camera can capture. 4 Megapixels (MP) is significantly more detailed than standard Full HD (which is 2MP). This high resolution allows you to digitally zoom in on the footage and still see clear details, which is crucial for identifying faces, license plates, or other important elements.

Auto Day/Night Switch

• The camera is equipped with a light sensor. During the day or in well-lit conditions, it records in full color. As darkness falls, it automatically switches to black-and-white mode and activates its infrared (IR) illuminators, allowing it to see clearly even in complete darkness.

Image Enhancement Technologies: 3D DNR, HWDR, HLC, BLC

• These are technologies that automatically improve image clarity in difficult lighting conditions:
  • 3D DNR (3D Digital Noise Reduction): This feature reduces the visual "noise" or graininess that often appears in low-light video, resulting in a cleaner and clearer image.
  • HWDR (Hardware Wide Dynamic Range): This balances the lighting in scenes that have both very bright and very dark areas at the same time (e.g., viewing a person standing in front of a bright window). HWDR ensures that details are visible in both the shadows and the highlighted areas.
  • HLC (Highlight Compensation): This function detects and masks extremely bright sources of light, like car headlights or spotlights, preventing them from "blinding" the camera and obscuring the rest of the scene.
  • BLC (Backlight Compensation): This improves the visibility of a subject that has a strong light source behind it. It works by brightening the foreground to make the main subject more visible.

ROI (Region of Interest) Coding

• This feature allows you to select the most important part of the camera's view (e.g., a doorway, a cash register, a gate). The camera will then allocate more of its data bitrate to record this "region of interest" in the highest possible quality, while recording the less important background areas at a lower quality. This is a smart way to optimize storage space without sacrificing detail where it matters most.

Support for Smart Supplement Light

• The camera can intelligently control its built-in light source (whether it's visible white light or invisible infrared). For instance, instead of being on all the time at night, the light can be set to activate only when motion is detected. This saves energy and makes the camera less conspicuous.

Viewing Distance: 30-40m (White Light); 30-50m (Infrared)

• White Light (30-40 meters): The camera can emit a visible white light, similar to a floodlight, to illuminate the area within this range. This allows it to record in full color, even at night.
• Infrared (IR) View (30-50 meters): The camera uses invisible infrared LEDs to see in complete darkness within this range. The resulting video is in black and white.

Power Supply: DC12V / PoE

• The camera can be powered in two ways:
  • DC12V: This is the traditional method, using a standard power adapter that plugs into a wall outlet.
  • PoE (Power over Ethernet): This is a highly convenient technology that allows the camera to receive both power and a network connection through a single Ethernet cable. This simplifies installation, as you don't need to run a separate power line to the camera's location.

Ingress Protection Rating: IP67

• This rating indicates the camera's resistance to dust and water.
  • The first digit, 6, means it is completely sealed and "dust-tight."
  • The second digit, 7, means it is protected against immersion in water up to 1 meter deep for 30 minutes.
  • Conclusion: The camera is fully weatherproof and suitable for outdoor installation in any environment.

Support for Three Streams

• The camera can transmit three independent video streams simultaneously. This is useful for various applications:
  1. Main Stream: The highest resolution, used for recording to your NVR or SD card.
  2. Sub Stream: A lower resolution, ideal for smooth live viewing on a smartphone or tablet without using too much data.
  3. Third Stream: Another stream that can be configured for other purposes, like cloud storage or integration with third-party systems.

Remote Monitoring (via Smartphone/Tablet)

• You can securely access your camera from anywhere in the world using a dedicated app on your smartphone or tablet (both iOS and Android operating systems are supported). This allows you to view live footage and playback recorded videos remotely.

P2P Function Support

• Peer-to-Peer (P2P) technology greatly simplifies the process of setting up remote viewing. It eliminates the need for complex network configurations like static IP addresses or port forwarding. Typically, you just need to scan a QR code on the camera with your phone's app to establish a connection.

SMD (Smart Motion Detection) Support

• Unlike standard motion detection, which can be triggered by any movement (swaying trees, rain, shadows), Smart Motion Detection uses an algorithm to analyze shapes and patterns. It is designed to specifically detect humans and/or vehicles, dramatically reducing the number of false alarms you receive.

Video Analytics Functions (Line Crossing, Intrusion Detection, etc.)

• These are "smart" features that automatically analyze the video feed and alert you to specific events:
  • Line Crossing Detection: You can draw a virtual line across a specific point in the camera's view (like a driveway entrance). The camera will send an alert whenever someone or something crosses that line.
  • Region Intrusion Detection: You can define a specific virtual area or "box" in the scene. An alarm will be triggered if a person or vehicle enters or loiters within that protected zone.
  • Abandoned/Missing Object Detection: The camera can detect if an object (like a suspicious bag) is left behind in a monitored area, or conversely, if an existing object (like a painting on a wall) is removed.
  • Video Exception Detection: The camera can self-diagnose issues and alert you to tampering, such as the lens being covered, spray-painted, or if the camera is suddenly moved or put out of focus.
