Revolutionary Instastream Compression Technology

Up to 70% Bandwidth and Storage Savings

CP Plus’s proprietary Instastream compression represents a significant advancement beyond standard H.265 encoding. By implementing intelligent region perception algorithms that detect motion and activity within video frames, Instastream dynamically allocates encoding resources where they’re needed most.

Static background areas like walls, floors, and unchanging scenery receive minimal encoding bits, while active regions containing people, vehicles, or movement receive maximum quality allocation. This smart approach delivers:

• 70% reduction in bandwidth consumption compared to H.265, enabling more cameras on existing network infrastructure
• 70% reduction in storage requirements compared to H.265, extending recording retention periods without additional hard drives
• Maintained visual quality in areas of interest while compressing static regions aggressively
• Lower total cost of ownership through reduced network equipment and storage hardware requirements

For organizations managing large camera deployments, these savings translate directly to bottom-line cost reductions. A 100-camera installation using Instastream might require only 30% of the network switches and storage arrays compared to traditional H.264 compression, while maintaining superior image quality.

Artificial Intelligence for Smart Surveillance

SMD Plus (Smart Motion Detection Plus)

Traditional motion detection systems generate overwhelming numbers of false alarms triggered by shadows, lighting changes, falling leaves, rain, and other environmental factors. The CP-UNR-4K2161-V4 addresses this challenge through SMD Plus technology that uses deep learning algorithms to classify detected motion into specific categories.

The AI engine analyzes video frames in real-time, identifying and classifying:

Human Detection: Recognizes human body shapes and movements, distinguishing people from animals, shadows, and inanimate objects. When a person enters a monitored zone, the system generates an alert while ignoring a cat walking through the same area.

Vehicle Detection: Identifies cars, trucks, motorcycles, and other vehicles, separating them from other moving objects. This capability is essential for parking lot monitoring, traffic flow analysis, and vehicle access control.

False Alarm Filtering: The secondary filtering system analyzes detected events, automatically discarding false positives caused by:

• Tree branches and leaves moving in wind
• Rain, snow, or fog affecting camera visibility
• Lighting condition changes from clouds, headlights, or reflections
• Small animals like birds, cats, or dogs
• Shadows moving across detection zones

SMD Plus operates at 8 targets per second processing speed across all 16 channels, ensuring real-time analysis without introducing latency. When AI is enabled, the system intelligently allocates resources, processing 4 channels at 1080p resolution while maintaining comprehensive coverage.

Perimeter Protection

Advanced perimeter protection capabilities enable virtual fence creation around property boundaries, restricted areas, or high-value assets. When a person or vehicle crosses defined boundary lines or enters protected zones, the system generates immediate alerts.

Perimeter protection excels in applications including:

• Industrial facility perimeters preventing unauthorized access to restricted areas
• Retail back-of-house regions alerting when customers enter employee-only zones
• Educational campuses monitoring after-hours building access
• Residential communities detecting intrusion attempts along property boundaries
• Healthcare facilities protecting sensitive areas like pharmaceutical storage

All channels support perimeter protection simultaneously, processing 4 targets per second across the entire 16-channel installation. Virtual tripwires and intrusion zones are configured through the intuitive web interface or KVMS Pro Lite software, with adjustable sensitivity to balance detection accuracy with false alarm prevention.

High-Bandwidth Architecture for Multi-Camera Systems

144Mbps Network Capacity

The CP-UNR-4K2161-V4 is engineered for high-bandwidth surveillance applications, supporting 144Mbps incoming bandwidth, 144Mbps recording bandwidth, and 72Mbps outgoing bandwidth when AI features are disabled. This substantial capacity accommodates multiple high-resolution camera streams without introducing latency, dropped frames, or recording gaps.

To put this in perspective, a typical 4MP camera using H.265 compression consumes approximately 4-6 Mbps of bandwidth. The NVR’s 144Mbps capacity comfortably handles 24-36 such cameras simultaneously—more than sufficient for the 16-channel maximum. This overprovisioning ensures consistent performance even during high-activity periods when all cameras are recording motion simultaneously.

When AI features are enabled, the system automatically adjusts bandwidth allocation to 72Mbps incoming/recording and 36Mbps outgoing, prioritizing processing resources for intelligent analytics while maintaining recording reliability.

Gigabit Ethernet Connectivity

A single 10/100/1000 Mbps Gigabit Ethernet port provides network connectivity, supporting both camera input traffic and remote viewing/management traffic on a single interface. The integrated network stack includes advanced features:
