Clear- Number of Channels: The maximum number of cameras that can be connected to and managed by the recorder.
- NVR: Recorder that uses IP cameras and network connection for video recording and management.
- DVR: A recorder that works with analog cameras, converting their signal to digital for storage.
- HVR: Combination of NVR and DVR, supports both analog and IP cameras simultaneously.
- Human Detection: It analyzes movement and recognizes the silhouette of a person. This way, the system sends notifications only for human presence, ignoring false alarms from pets, leaves, or shadows.
- Vehicle Detection: Recognizes the shape of vehicles. Suitable for parking areas or roads, sending notifications only for vehicles and ignoring other insignificant movements.
- ONVIF: An open protocol that allows cameras and recorders from different manufacturers to communicate with each other. It provides the flexibility to combine cameras from one manufacturer with a recorder from another.
- PoE: Each PoE port provides power and data through the same cable (plug-and-play).
- Pre-installed HDD: The device comes with the hard drive already installed and configured.
- 4K: The top choice for ultimate detail. Essential if you want to digitally zoom in on the recorded image to clearly distinguish faces, license plates, or details in large areas, without the image breaking up.
- Full HD: The market standard for everyday use. The most widespread resolution, offering very clear image quality for the majority of applications (homes, small shops). Ensures a good balance between image quality and storage space
- Full HD+: Covers resolutions higher than standard 1080p (such as 4MP and 5MP), which are now the standard in quality security cameras. Offers noticeably better clarity than Full HD, allowing for improved object recognition.
- HD: Mainly suitable for older technology cameras or for very simple area monitoring (e.g. a storage room) where it is sufficient to observe movement without requiring high clarity or feature recognition.
- Number of PoE: Specifies how many IP cameras can be connected directly to the recorder (NVR) and powered by it. Each PoE port provides both power and data through the same cable (plug-and-play).
- Gigabit: Port with 10 times faster network speed (1000 Mbps) compared to standard (100 Mbps). It is essential for systems with many cameras or 4K cameras, as it ensures smooth handling of large amounts of data.
- Video Compression: The technology that "shrinks" the video file. H.265+ uses half the space compared to H.264, offering twice as many days of recording. At the same time, the systems provide backward compatibility, fully supporting older cameras as well
- H.265+: It is the most advanced compression. It "shrinks" video files significantly without losing quality. The benefit: It gives you double or even triple recording time on the same hard drive compared to older recorders. Ideal for larger backups
- H.265: It is the successor to the older H.264. It is essential if you have high-resolution cameras (4MP and above), as it manages data much more efficiently, so the disk does not fill up immediately.
- H.264: Suitable for connecting older cameras. Videos take up more space on the hard drive compared to modern ones (H.265), so storage may fill up more quickly.
- H.264+: It is reliable, but video files take up more space than H.265/H.265+. It is mainly recommended for budget systems with a small number of low-resolution cameras.
- Hard Drive Bays: The number of internal hard drives (SATA) that can be installed simultaneously in the recorder. The hard drive is not included
- Incoming Bandwidth (Mbps): Specifies how much "heavy" image data can be handled simultaneously. The higher it is, the better image quality (bitrate) each camera can have, without "freezing" or delays.
- 40: Sufficient power for simple, home installations. Ideal for recording cameras with low to medium resolution (Full HD / 2MP) using basic quality settings.
- 80: Easily manages a typical setup with a mix of Full HD and 4K cameras, ensuring smooth image streaming without interruptions.
- 160: Allows recording at maximum resolution (4K) and highest image quality (High Bitrate), without overloading the system or losing details.
- 256: Designed to handle a massive volume of data, allowing all connected cameras to operate at 100% of their capabilities (Max Resolution & Max Frames) without any compromise in quality.
