Ultra-Thin Micro DVR with WiFi Live View and App Control
The CDVR23 SPIKE is an ultra-thin micro DVR for covert video, body-worn recording, custom concealments, and compact analog surveillance systems. At just 0.4 inches thick and approximately 13 grams, it can be hidden where conventional recorders simply will not fit.
Micro DVR for Covert Video Where Space Is the Enemy
The CDVR23 is built for surveillance applications where the recorder must be extremely small, easy to hide, and simple to control. It can be used with compatible composite video cameras and line-level microphones, making it a practical DVR for button cameras, pinhole cameras, custom concealments, body-worn-style systems, office fixtures, books, utility enclosures, and other tight installations.
Ultra-Thin Concealment Profile
With a thin profile of approximately 0.4 inches, the CDVR23 can be placed in tight spaces where a typical DVR would be too bulky, too obvious, or too difficult to conceal.
WiFi Live View and Control
Built-in WiFi allows live video streaming to a smartphone or tablet, with app-based control for recording, snapshots, file review, settings, and system status.
Analog Camera Friendly
The CDVR23 accepts compatible composite NTSC or PAL video, making it useful with many analog pinhole cameras, button cameras, micro cameras, and specialty covert camera heads.
Why the SPIKE Micro DVR Is Useful in the Field
Many covert deployments fail because the recorder is too large, hard to access, or difficult to configure once hidden. The CDVR23 solves that problem by combining a small physical package with wireless setup and review from a smartphone or tablet.
For Body-Worn and Clothing Concealments
The thin body and light weight make the CDVR23 a strong fit for body-worn video packages, clothing-based concealments, shoulder bags, and other operator-carried systems.
For Hidden Objects and Fixtures
The recorder can fit inside many utility enclosures, books, office fixtures, equipment housings, and custom surveillance objects where larger DVRs are not practical.
For Remote Setup and Review
WiFi control allows the user to adjust settings, start recording, capture photos, browse files, and review footage without immediately disturbing the physical concealment.
WiFi Control from a Smartphone or Tablet
The built-in 2.4GHz WiFi transmitter allows live video to stream securely to a compatible smartphone or tablet. From the app, users can remotely start recording, capture still images, review previously recorded footage, and adjust DVR settings.
In MAXSUR office testing, WiFi range was experienced at approximately 100 feet. In line-of-sight conditions, users may see up to approximately 300 feet depending on environment, interference, device, antenna orientation, and placement.

Recording Options and Storage
The CDVR23 records H.264 video in AVI format and supports both standard recording and motion detection recording. The included 8GB microSD card can provide up to approximately 8 hours of constant recording at 30FPS, and larger microSD cards up to 64GB may be used.
Adjustable Frame Rate
Select frame rate options including 10, 15, 20, 25, or 30 FPS based on the mission’s balance of motion quality, file size, and recording duration.
Motion Detection
Motion detection recording can help conserve storage and reduce the amount of video that must be reviewed after the deployment.
Phone or DVR Storage Options
App settings allow video and photo memory allocation to the DVR or phone, depending on how the user wants to capture and review files.
Best Fit Applications
The CDVR23 is best used when the mission needs a very small recorder, compatible analog video input, local DVR storage, and short-range wireless access for setup or review.
Covert Body-Worn Video
Pair with compatible button, pinhole, or micro cameras for body-worn-style recording where the DVR must remain light and easy to conceal.
Hidden Camera Systems
Use inside books, fixtures, utility enclosures, cabinets, bags, equipment housings, and other custom concealments where recorder size is critical.
Temporary Surveillance
A practical fit for short-duration covert video setups where local recording, WiFi review, and small physical size are more important than a full-size DVR.
Mobile and Vehicle Kits
The 5VDC micro USB power input and small footprint make it useful for compact mobile kits, vehicle-based systems, and technician-built recording packages.
Shop Testing and Camera Setup
Use as a compact DVR for testing analog camera output, microphone compatibility, motion recording, frame-rate settings, and storage behavior.
Custom Covert Builds
A strong option when an integrator needs a thin DVR module with app access for a custom camera, microphone, power, and concealment design.
