Enhance Your Surveillance Network With A Smart NVR

Build an adaptable and intelligent surveillance system with the Seco-Larm ENFORCER 4K Network Video Recorder, 4-Channel, 2TB HDD! This network video recorder hosts and records live video from connected IP cameras in up to 8MP / 4K resolution and utilizes advanced AI powered functions to improve surveillance and smart security tasks. 1 SATA port is available for connecting the NVR to other NVRs to expand the size of your surveillance network or to separate memory storage units to save recorded footage. Additional design choices such as PoE ports, a variety of physical inputs, tri-stream encoding, and plug-and-play installation allow the NVR to work with virtually any surveillance system for a wide range of applications.

  • Network Video Recorder supports multiple simultaneous 8MP/4K video streams and playback
  • Plug-and-play PoE with up to four compatible IP Cameras
  • Review recorded footage at adjustable resolutions and FPS (720p@120FPS to 4K@30FPS)
  • AI functions, i.e. human and vehicle recognition, heat mapping, and more provide advanced security and playback capabilities
  • QR Code and Wizard Install assistance provide easy first-time setup
  • Built-in PoE Ports (IEEE 802.3af/at) with Plug-and-Play functionality

This NVR supports up to 4K resolution (3840 x 2160) at 30fps and can record simultaneous HD streams at 48 Mbps across all four channels. Built-in AI technology assists live surveillance and during review of recorded footage to improve the capabilities of your security and/or surveillance network. Features such as perimeter intrusion or line crossing can trigger connected alarms and improve responsiveness of security or emergency services. Face detection, vehicle and object detection, and crowd density and heat mapping features improve playback review and shorten the amount of time spent scrubbing footage for particular results. If a EV-N2806-2W4WQ 8MP Turret IP Camera is connected to the NVR, the camera's facial recognition and license plate detection capabilities can be utilized by the NVR.

The 4-Channel 4K NVR has 2 terabytes of local storage and connects to the Internet to provide remote management and access to the system from most common web browsers and the SL Vision mobile app. Cameras can auto-enroll into the NVR over built-in PoE+ connections, making installation quick and simple. The network video recorder is capable of supporting additional storage by replacing the included SATA HDD with a larger storage drive, up to 10 terabytes.
