The Tactical Under Door Camera is a compact, field-deployable Remote Visual Inspection (RVI) system designed for covert visual access into enclosed spaces behind closed doors, barricades, and other obstructed entry points. The system is intended for police under door camera, law enforcement under door camera, military under door camera, and security inspection tasks where rapid situational awareness is required prior to entry.

The device is based on a thin under-door insertion panel approximately 0.26 in (6.6 mm) thick, allowing deployment under standard door gaps or in similarly restricted clearances. Depending on configuration, the system may incorporate one, two, or four camera modules, providing forward, upward, and lateral observation capability. Illumination is provided by covert 950 nm infrared LEDs, enabling inspection in low-light and no-light environments without visible light emission. Video may be transmitted wirelessly through an encrypted 5 GHz link or through a hardwired connection in RF-restricted environments. Source materials also describe direct-view, monitor-based, and Android/mobile-device-based operating configurations.  

The Tactical Under Door Camera is engineered as a low-profile inspection system optimized for covert insertion, controlled handling, and deployment in confined operational environments. The insertion panel thickness of approximately 0.260 in / 6.6 mm supports access beneath doors with limited floor clearance. Depending on model and configuration, the camera body remains compact enough for rapid stowage and field carriage, while optional handheld grip, pole-mounted, or direct-cable deployment concepts permit operation from a tactically offset position.

The housing materials include reinforced polymer and aluminum structural elements intended to withstand operational handling and repeated insertion cycles. Reported operating temperature capability extends to approximately -20 °C to +50 °C depending on system configuration. Certain variants are battery-powered by CR123 cells, while other configurations are powered through an attached monitor, external device, USB/Ethernet interface, or auxiliary 12 VDC input. 

The Under Door Camera employs low-light-sensitive color CMOS image sensors integrated into the insertion panel. Depending on configuration, the system may provide: 

• Single-camera forward view
• Dual-camera forward and upward view
• Multi-camera forward, upward/backward, left, and right views

Key imaging parameters include:

• Low-light color CMOS imaging
• Camera resolution up to 640 × 480 at 30 fps
• Horizontal field of view approximately 87°
• Covert 950 nm IR LED illumination
• Camera switching between available views
• Real-time live video for covert reconnaissance and inspection  

The Tactical Under Door Camera System supports multiple display and transmission architectures depending on configuration. Supported options include 5 GHz real-time wireless video transmission with 128-bit AES encryption and WPA2-PSK authentication, as well as hardwired video/data interfaces for RF-restricted or infrastructure-based use. In various configurations, video may be viewed on a dedicated monitor, direct-view eyepiece, or Android mobile device. USB and Ethernet interfaces are also described for system integration and data transfer.

Data handling capabilities include:

• Real-time live video transmission
• Wireless encrypted video link
• Hardwired operation for restricted environments
• Video recording to 32 GB MicroSD
• Still image capture in live-view workflows
• USB/Ethernet data transfer in applicable configurations  

The Police Under Door Camera / Law Enforcement Under Door Camera platform may be deployed in several operational modes derived from the OEM concept:

• Direct handheld deployment
• Grip-assisted deployment
• Telescoping pole deployment for standoff inspection
• Direct connection to mobile or monitor-based documentation units
• Wireless operation for untethered observation
• Hardwired operation for RF-sensitive or communication-controlled environments

The Tactical Under Door Camera may be equipped with an integrated microphone located near the camera assembly to support synchronized audio monitoring during inspection. This capability allows the operator to capture environmental sounds from the inspected space while conducting visual reconnaissance. Audio and video signals are transmitted simultaneously and may be recorded together with the video stream, providing additional situational information during police, law enforcement, security, and military under-door inspection operations.

The Tactical Under Door Camera is suitable for:

• Covert pre-entry inspection
• Police room-clearance support
• Law-enforcement warrant service and barricade assessment
• Military room-entry reconnaissance
• Security inspection behind closed or obstructed doors
• Inspection of confined or inaccessible spaces adjacent to entry points
• Verification of barricades, obstacles, or hazards on the reverse side of a door
• Remote visual inspection tasks where visible illumination is undesirable or prohibited
