4K SECURITY CAMERAS
9/26/20244 min read
When it comes to protecting your home, 4K security cameras have redefined what it means to capture and monitor activity clearly and effectively. Their advanced features not only offer ultra-high-definition recording but also provide smart functionalities and durable builds suitable for various environments. In this article, we’ll dive into the technical details that make these cameras a standout choice for modern home security.
1. High-Quality Image Sensor and Clarity
A key component of any security camera is its image sensor. These 4K cameras are equipped with a 1/2.8'' Progressive Scan CMOS sensor, which provides exceptional clarity and sharpness. This sensor captures effective pixels at 2592(H)×1944(V), ensuring every detail is visible.
How does this benefit you?
A higher pixel count means clearer and more detailed recordings, so you'll be able to easily identify faces, license plates, and other important details. The 5MP max resolution also means that even when zooming in, you'll retain high image quality without much pixelation.
2. Adaptability to Light Conditions
4K cameras come with a range of features that allow them to function effectively in varying lighting conditions:
Electronic Shutter: Capable of both auto and manual control with a speed range of 1/5 ~ 1/20,000S, ensuring the camera can capture clear images in both fast and slow motion.
Minimum Illumination: With a color mode sensitivity of 0.05 Lux (F1.2, AGC ON) and 0 Lux in IR mode (infrared light), these cameras are designed to perform even in low-light or complete darkness.
True WDR (Wide Dynamic Range): This feature balances bright and dark areas in the frame, allowing for clear footage even in challenging lighting situations, such as bright sunlight or shadows.
How does this benefit you?
Your camera will be able to adapt to different lighting conditions throughout the day, whether it's bright sunlight, dim twilight, or complete darkness. The IR range up to 30m (98 ft) also provides night vision capabilities, so you can monitor your property 24/7.
3. Comprehensive Field of View and Lens Specifications
The lens of a camera determines its field of view and how much area can be captured in a single frame. 4K security cameras come with:
Fixed-Focus Lens: A 2.8mm lens (with a 4mm optional upgrade), offering a wide-angle view.
F Number: The lens has an F2.0 aperture, allowing more light to enter and improve image quality, especially in low-light conditions.
Pan/Tilt Rotation Range: With a pan range of 0˚ ~ 360˚, tilt range of 0˚ ~ 90˚, and rotation of ±60˚, these cameras offer flexibility in positioning to ensure maximum coverage.
How does this benefit you?
The wide angle of view (H: 93.4°, V: 69.1°) allows the camera to monitor larger spaces with fewer blind spots. You can also adjust the camera's positioning to cover different parts of your property without needing multiple devices.
4. Advanced Video and Streaming Capabilities
For both live monitoring and recording playback, 4K cameras come with robust streaming features:
Streaming Capability: Support for three simultaneous streams allows for efficient video transmission and playback in various formats.
Stream/Frame Rates: The camera supports different resolutions at 25/30 FPS, ensuring smooth and high-quality video. It includes:
Stream1: Up to 2560×1920, 2592×1520, 1920×1080, and 1280×720.
Stream2: D1, VGA, and CIF.
Stream3: VGA, CIF, and QVGA.
Bit Rate Control: Options for CBR/VBR provide flexibility in managing video quality and storage requirements.
Bit Rate Range: The bit rate varies depending on the stream, with Stream1 supporting 200KBPS ~ 12MBPS, Stream2 supporting 100KBPS ~ 6MBPS, and Stream3 supporting 100KBPS ~ 3MBPS.
How does this benefit you?
The ability to stream and record in various resolutions and frame rates helps tailor the camera's performance to your network capacity and storage needs. The multiple streaming options make it easier to view live footage in high quality while saving storage space on recorded files.
5. Image Enhancements and Smart Features
To improve image clarity and usability, 4K security cameras are equipped with several enhancement and smart detection features:
Image Enhancement: Tools like HLC (Highlight Compensation), BLC (Backlight Compensation), DEFOG, and WDR improve image quality in various conditions.
Noise Reduction: With 2D/3D DNR (Digital Noise Reduction), the camera minimizes visual noise and graininess for clearer images.
Smart IR: Automatically adjusts the IR LED intensity based on the distance of objects, preventing overexposure and ensuring better night vision.
Smart Detection: These cameras support motion detection, face detection, human and vehicle detection, and can create virtual fences or zones for customized alerts.
How does this benefit you?
You'll get crisp, high-quality footage regardless of the lighting or environmental conditions. The smart detection features ensure that the camera focuses on relevant movements (like people or cars), minimizing false alarms.
6. Audio, Network, and Storage Features
For comprehensive surveillance, 4K cameras support audio recording, flexible storage, and network compatibility:
Audio Compression: Using G.711 or RAW_PCM formats, the cameras provide clear audio recording, with bit rate options of 8KBPS, 16KBPS, and 64KBPS.
Network Protocols: Fully compatible with IPv4/IPv6, HTTP/HTTPS, TCP/IP, UDP, RTSP, DHCP, NTP, and other standard protocols, ensuring reliable connectivity and interoperability.
Storage: The built-in micro SD slot supports up to 256GB, providing additional local storage options for critical footage.
How does this benefit you?
The audio capabilities allow for two-way communication or recording ambient sounds for more comprehensive surveillance. With multiple network protocols, the camera easily integrates into most security setups, and the local storage option provides backup for important recordings.
7. Power Supply and Environmental Durability
The build quality and power options of 4K cameras are designed for long-lasting performance:
Power Supply: Supports DC12V/PoE (IEEE 802.3AF), which simplifies installation by allowing power and data transmission over a single Ethernet cable.
Power Consumption: The camera consumes a maximum of 7.5W, making it energy-efficient.
Environmental Resistance: With an IP66 rating, the camera is weatherproof and can withstand outdoor conditions like rain, dust, and extreme temperatures (-40°C ~ 55°C / -40°F ~ 131°F).
How does this benefit you?
These cameras are durable and suitable for use in various environments, both indoors and outdoors. The PoE support ensures simple and clean installation, while their weather-resistant design means they can function in a variety of climates and conditions.
