Can you use your digital freeview box as your dvr for cctv?

No, a digital Freeview box is not designed to function as a DVR for CCTV systems. Freeview boxes are intended for receiving and recording Broadcast Television signals, while CCTV systems require specific recording devices that can handle video feeds from security cameras. To record CCTV footage, you would need a dedicated DVR or NVR (Network Video Recorder) that supports the necessary video formats and storage requirements.
