Recorder is a great way to migrate your analog CCTV into a digital surveillance solution. This is a low-cost option that brings a number of benefits to those who already own analog cameras, or aren’t yet ready to make the move to a fully IP-based surveillance system. Most digital video recorders now allow you to access your camera footage remotely over the internet. By connecting your analog cameras to a DVR, you can monitor video feeds in real-time from any computer with internet access, and even from compatible cell phones or handheld PDAs.
A Digital Video Recorder (DVR) contains software, video storage, and a computer hard disk all in a single unit. The DVR accepts analog video feeds and converts them to digital. It’s a cost-effective way to bring an analog CCTV system into the modern world and provides some of the same benefits as IP video but in a more budget-friendly solution. With DVRs, your footage is converted from analog-to-digital, so you can store significantly more video without the clutter, and it’s much faster and easier to sort through archived footage.
A Network Recording Device(NVR) uses the local network to send and receive data and is ideal for remotely monitoring your surveillance system from your computer, smartphone, or tablet. Because IP cameras are the cutting edge of surveillance technology, including an NVR in your system allows you to include new cameras with more advanced features. While most IP cameras and NVRs are compatible, you should always check with your surveillance system integrator to ensure all your products will work together properly.
Network Video Surveillance(NVS) systems are inherently more flexible because security cameras don’t necessarily have to be physically connected directly to the recorder. Instead, IP cameras only have to be on the same network. As such, you could feasibly have cameras all over the world on the same network that connect to your NVS can then be viewed as a comprehensive system. NVS systems tend to have better picture quality, as well as easier installation, increased flexibility, and native support for audio on every camera that has a microphone.
