• NVR (Network Video Recorder) Systems: Use IP (Internet Protocol) cameras. These cameras process video data themselves before sending it to the recorder. NVR systems often utilize PoE (Power over Ethernet), where a single Ethernet cable provides both power and data transmission to the camera, simplifying wiring. They generally offer higher resolutions and more advanced features.
• DVR (Digital Video Recorder) Systems: Use analog cameras connected via coaxial cables (like BNC connectors). The DVR processes the video data from the cameras. While traditionally offering lower resolutions, modern DVRs (like those from ZOSI) can support high-definition analog cameras (HD-TVI, CVI, AHD). They can sometimes be more budget-friendly or suitable for upgrading existing coaxial wiring.

This depends on your needs:

• Wired Systems (Typically PoE NVR or Coaxial DVR): Offer the most reliable connection as they aren't susceptible to Wi-Fi interference. PoE NVR systems simplify wiring by using one cable per camera for power and data. Ideal for new installations where running cables is feasible or maximum stability is required.
• Systems with Wireless Cameras: Some systems might include Wi-Fi cameras that connect wirelessly to your network (and potentially the NVR/DVR). These offer more installation flexibility but still require a power source near each camera. Performance depends on Wi-Fi strength. Note: The NVR/DVR itself will still typically need a wired connection to your router for remote access.

Consider the key areas you want to monitor:

• Entrances & Exits: Front door, back door, garage door, gates.
• Ground Floor Windows: Especially those easily accessible or hidden from view.
• Key Outdoor Areas: Driveway, yard, patio, vulnerable side areas.
• Important Indoor Areas (if applicable): Main hallways, common areas, rooms with valuables.
• ZOSI offers systems with varying camera counts (e.g., 4, 8, 12, 16, 24, 32 cameras). It's often wise to choose a system with slightly more channels than you initially need, allowing for future expansion.

Higher resolution provides clearer images. ZOSI systems are available in various resolutions:

• 1080p (2MP): Good standard definition, suitable for general monitoring.
• 3MP/4MP/5MP: Offer significantly more detail than 1080p, better for identifying faces or license plates at a distance. Excellent mid-range options.
• 4K (8MP): Provides the highest level of detail, ideal for covering large areas or requiring forensic-level clarity.

Consider the trade-off: higher resolution requires more storage space and bandwidth.

Most ZOSI NVR and DVR systems come with a built-in hard disk drive (HDD) specifically designed for surveillance recording. Capacities vary (e.g., 1TB, 2TB, etc.). The system can be set to record continuously, on a schedule, or only when motion is detected to save storage space. Footage is typically overwritten automatically when the hard drive is full (oldest footage first). Some systems may also offer backup options like USB drive export or optional cloud storage integration.

ZOSI systems are designed with DIY installation in mind.

• PoE NVR Systems: Relatively straightforward as each camera connects to the NVR with a single Ethernet cable.
• DVR Systems: Require connecting both coaxial (video) and power cables for each camera.
• Setup: Connecting the NVR/DVR to your router and TV/monitor, and configuring basic settings via the on-screen interface or app is generally user-friendly. ZOSI provides manuals, online tutorials, and customer support to assist you. However, running cables neatly can take time and effort.

Yes. Once your NVR/DVR is connected to the internet, you can use the ZOSI Smart App (iOS/Android) or AVSS Client software (PC/Mac) to view live feeds from all connected cameras, playback recorded footage, and manage system settings from anywhere.

Yes, virtually all cameras included in ZOSI security systems feature night vision capabilities, typically using infrared (IR) LEDs for clear black and white images in complete darkness. Some advanced systems may include cameras with color night vision technology for enhanced detail in low light.

Yes, provided your NVR or DVR has available channels. For example, an 8-channel NVR can support up to 8 cameras. If you buy a kit with 4 cameras and an 8-channel NVR, you can add up to 4 more compatible ZOSI cameras later. Always check the system specifications for the maximum number of channels and camera compatibility.

A standard kit usually includes:

• The NVR or DVR unit (often with a pre-installed hard drive)
• The specified number of security cameras
• Cables for each camera (Ethernet for PoE NVRs, Coaxial & Power splitters for DVRs)
• Power adapter(s) for the NVR/DVR and cameras (if not PoE)
• A USB mouse for controlling the NVR/DVR interface
• Mounting screws and hardware for the cameras
• Quick start guide and manuals
• (Often) An HDMI cable and/or Network cable

The system will record locally to the hard drive without an internet connection. However, an internet connection for the NVR/DVR is required for remote viewing via the app/software, receiving push notification alerts, performing firmware updates, and utilizing any cloud storage features.
