ZOSI 16CH 1080P H.265+ CCTV DVR Security System with 4TB HDD — 8PCS Outdoor/Indoor Bullet Cameras, 80ft IR Night Vision

Reliable 16-channel surveillance solution — This 16 Channel Full 1080P 4-in-1 DVR (supports analog HD-TVI, CVI, AHD cameras) gives you a complete home or business monitoring setup and room to expand. The package includes 8PCS bullet cameras suitable for outdoor or indoor use with 80ft IR night vision for low-light protection. The system is built around H.265/H.265+ compression to double data compression efficiency, maintain high-quality video at low bitrates, and maximize storage for ultra-long recording. Customizable motion detection & alerts — Configure motion detection zones per camera to avoid false alarms from moving foliage or wildlife, and use privacy masking to block areas you don’t want monitored. When motion is detected the system sends instant notifications and email alerts with a screenshot directly to your phone. Flexible recording options per camera — Choose from four recording modes for each camera: continuous recording, scheduled recording, motion-triggered recording, or recycle (overwrite) recording. This lets you tailor storage use and recording behavior to each camera’s location and purpose. Expandable and compatible — The DVR supports adding extra cameras; you can add more 4pcs 720P or 1080P bullet or dome cameras to increase coverage. The recorder ships with a built-in 2TB security-grade hard drive to support long-term continuous recording. Backup and overwrite management — Back up footage easily via USB to a memory stick or external hard drive. The NVR/DVR can also be set to automatically overwrite the oldest internally stored videos to free space when needed.
