4K Recording Resolution

DW's recorders deliver crystal clear images in any resolution. Higher resolution offers forensic details with zooming into the camera's field of view.


Easy and secure remote connection with NAT Traversal (STUN/TURN) support without opening ports.

CCIP™ System Encryption

The CCIP™ (Closed Circuit IP) encryption is activated when the VMAX IP G4™ system sends a request for an encrypted stream from the camera. The camera then encrypts its RTSP stream a second time using TLS, using the encryption's user ID and password. The result is a secured and encrypted RTSP stream that can be read only by the requesting recorder.

C3™ CMS takes video management to the next level. You are in complete command to control all your video surveillance systems in one intuitive interface. Easy-to-program alerts let you take action in real-time and manage the health of your devices.

DW Witness™ App

The DW Witness™ app for iOS® and Android® instantly turns your smartphone or tablet into a video surveillance camera. Press the button on the app and start transmitting live video to your VMAX IP G4™ NVR. It’s a “black box” for personnel on patrol.

Push notifications via DW Mobile Plus App

DW’s recorders can send an event notification to your mobile device via the DW Mobile Plus app.

Real-Time Streaming Protocol (RTSP)

RTSP provides a live video stream for live streaming applications between DW VMAX® G4 recorders and third-party software applications. RTSP streams offer a secondary backup location for recorded video and smart home integration, an alternative for ONVIF integration and a way to broadcast a stream to live streaming services, such as CCTV live monitoring in animal sanctuaries and public cameras.

Status Monitoring

A real-time graphical representation of all system connections. Receive connection alerts via email or text.
