There are three main tasks HDDs do besides storage: read data, write data, and transfer data. Generally, surveillance HDDs are turned on 24 hours/7 days a week. They write data and store footage from security video most of the time. They transfer them only a small portion of the time. Regular HDDs are designed for being used mostly to read data and are not typically tested for use in a 24x7 surveillance environment with the continuous demand of writing videos. Video surveillance HDDs are designed to endure heavy writing, from several closed-circuit television (CCTV) cameras simultaneously, consume low power, and endure environments with a wide range of temperatures.
Higher capacity drives allow you to store more footage, more high definition video, and more high quality frames per second. We recommends 4TB or greater for your DVR or NVR surveillance solution.
In short, DVR based CCTV systems are relatively simple set-ups owing to older technology; whereas, NVR based CCTV system are the latest technology, and better for business and complex usage. DVR’s are used with analog CCTV cameras while NVR’s are used with internet protocol (IP) cameras. In a DVR, the video is encoded and stored in the DVR, whereas with an NVR, this happens in the camera and the videos are then stored in the NVR for remote access. A DVR based security system is usually wired and each camera needs to be connected directly to the DVR. NVR based security systems are wireless and all cameras can be connected to a single network. In a DVR based system, you’ll have to consider extra wiring for recording audio. NVR CCTV systems are highly flexible and easy to scale up when your requirement grows larger.
