Security and intelligence,
in one device.
Tovitech's NQ series is a family of video security software built in-house around a security-hardened NVR with on-device AI analytics, plus control-room, on-site and mobile clients and tools for health monitoring and automatic backup. No cloud dependency: video and data stay on your own equipment.
The NQ series
One coherent family: core recording and analytics, control-room, on-site and mobile clients, health-monitoring and backup tools, and AI applications.
Core
Device-side core software for recording and AI analytics
NQNVR
FlagshipAI-powered, security-hardened NVR
A network video recorder that records up to 64 IP cameras, identifies people, vehicles, plates and fire with on-device AI, and protects storage, transport and key management end to end with AES-256-GCM.
NQVCA
On-device AI video analytics for NQNVR
The AI analytics subsystem built into NQNVR. Identifies people, vehicles, faces, fire and license plates in real time without any cloud, and raises events from intrusion, counting, fall and wrong-way rules.
Clients
Clients that connect directly to the NVR from control rooms, sites and phones
NQVMS
Multi-server desktop VMS
A Windows control-room client that connects to multiple NQNVRs at once and lets you arrange and monitor cameras freely: live multi-view, PTZ, playback, e-map, server health, and management of video walls and remote PCs.
NQMobile
Multi-NVR mobile client
An Android app that registers several NQNVRs and shows their live and recorded video on your phone. It talks to the NVR directly over HTTPS with no intermediate server.
NQWall
Stand-alone video wall software
Video wall software that turns a single PC into a control-room wall with no server, database or browser. It connects straight to NQNVR, lays cameras out on an automatic grid, and adds multi-monitor, spanning, frame sync and a remote control API.
NQPCAgent
Remote PC agent
A VNC-style agent that lives on each PC. NQVMS discovers it automatically, registers it like a camera, shows its screen, sends mouse and keyboard input and transfers files. A single static Go binary with no dependencies.
Operations
Tools that automate health monitoring and data protection across NVRs
NQNMS
NVR health monitoring
A health monitoring application that keeps watch over many NQNVRs and their cameras from a control-room PC. It tracks connectivity, disk, recording, temperature and clock drift, alerts by desktop, e-mail and Telegram, and produces long-term availability reports.
NQAutoBackup
Automatic multi-NVR backup
Automatically backs up recordings from multiple NQNVRs over the network to a separate PC. Three modes (mirror, daily at a set time, outage-only) plus automatic gap recovery, with results playable directly in NQBackupViewer.
NQBackupViewer
Backup playback viewer
A dedicated viewer that plays backups made by NQNVR's backup tool or NQAutoBackup on any Windows PC without an NVR. All you need is the backup folder and the password chosen at backup time.
Solutions & Integration
Application solutions that consume AI events over MQTT and REST API — integrate with existing systems or build new ones; the list keeps growing
NQPlateExtractor
Component appLicense plate extraction from recordings
A batch tool that rescans recordings already stored on the NVR to find and read vehicle plates. Results are saved as vehicle and plate images plus a per-day database and CSV, ready for settlement and reconciliation work.
NQVehicleTracker
Component appVehicle location and tracking
Subscribes to NQVCA plate-recognition events over MQTT and shows each vehicle's current position and path on a floor plan. In car parks and logistics yards it tells you instantly which camera zones a vehicle passed and where it is now.
Integrate with your existing applications
NQVCA's person, vehicle, plate, face, fire and thermal events are delivered in real time over MQTT and HTTP POST, and video, best shots and recordings are available through the NQNVR HTTPS REST API. Your existing control or business applications connect to these interfaces as they are. If you already run a solution like the ones below, MQTT and the REST API are all you need to use it with NQVCA; if the solution you need is not listed, ask us — we can build it together.
Subscribe to detection, plate, intrusion, counting and temperature-alarm topics. Customer servers, PLC gateways and alarm devices consume them directly.
Push events to a URL of your choice to connect existing control systems, PSIM and web services without code changes.
Query channels, health, best shots and playback with Digest SHA-256 authentication from your own dashboards and business systems.
All analytics and integration happen on your equipment. Video never leaves the site; only event metadata goes where it is needed.
Solutions built on NQVCA events
If you already have one of these solutions, you can connect it to NQVCA events and video directly over MQTT and the REST API with no extra development. Solutions you still need, we build together.
Plate extraction from recordings
Batch-rescans recordings and writes plate, time and image per lane to CSV and DB for toll and parking settlement.
Toll · parking · logistics
Parking control and vehicle locator
Consumes plate events over MQTT and shows each vehicle's position and path on a floor plan.
Car parks · logistics yards
Early fire alarm
Receives fire-detection and thermal temperature-alarm events over MQTT, triggers sirens, PA, SMS and control-room pop-ups, and brings up the camera at the source.
Factories · warehouses · electrical rooms · forests
Illegal parking enforcement
Combines vehicle detection with plate recognition to time how long a vehicle stays, plays a warning, then stores plate, time and evidence images.
Municipalities · fire lanes · bus stops
Automatic gate control
Matches recognized plates against a registered list to open the barrier, alerts staff for unknown vehicles and links to visitor booking systems.
Apartments · workplaces · public offices
Intrusion alarm integration
When intrusion is detected in a zone after hours, triggers strobes, sirens, SMS and control-room alerts and pops the channel up in NQVMS.
Military · substations · warehouses · schools
People counting and crowding alerts
Counts entries and exits on doorway lines, tracks occupancy, raises crowding alerts and produces hourly statistics.
Retail · public facilities · events · platforms
Fall and accident detection
Detects falls in workplaces, care facilities and single-occupant settings, alerts immediately and secures the video before and after.
Industrial sites · care homes · hospitals
Wrong-way and road incident detection
Detects wrong-way driving, stopped vehicles and pedestrians on the roadway and notifies signage and operators. For highways, tunnels and ramps.
Highways · tunnels · underpasses
Real-time toll plaza plate recognition
Recognizes plates of fast-moving vehicles per lane ROI in real time, forwards them to the tolling system and leaves best shots for manual review.
Toll plazas · toll roads
Face-based access and watch-list alerts
Identifies registered people with face re-identification, logs access and alerts operators on watch-list matches.
Workplaces · labs · finance
Danger-zone approach and machine stop
When a person enters the danger zone around machinery, sends a stop signal to the PLC gateway over MQTT and sounds an alarm.
Smart factories · construction · ports
Loitering detection
Alerts when a person or vehicle stays in an area longer than a threshold. For school perimeters, ATMs and parking blind spots.
Schools · finance · car parks
Logistics yard vehicle flow
Combines gate plate recognition with zone detection to report dwell time per vehicle, queues and throughput by hour.
Distribution centers · ports · factories
Thermal temperature monitoring
Continuously monitors surface temperature of transformers, switchboards and equipment with thermal cameras, with staged alarms and trend reports.
Substations · electrical rooms · data centers
Integration with existing control and business apps
Connects events and video to the VMS, PSIM, ERP or access-control systems you already run. MQTT, HTTP POST and REST specifications are provided, and custom adapters can be built.
Any sector

NQVMS at the center, monitoring many NQNVRs
In a real control center NQVMS is the main console: it registers many NQNVRs and handles live video, events, e-map and playback on one screen. NQVMS discovers and configures video walls (NQWall) and remote PCs (NQPCAgent), while NQNMS watches NVR health. Events from the NQVCA built into each NVR reach customer applications and solutions over MQTT and HTTP POST. A single NQNVR can of course also run on its own.
