Decoding Embedded NVRs consistently outperform PC-based NVRs in terms of complex decoding as well as being able to provide more reliable video playback and preview. Some of these NVRs are able to perform both local decoding and playback, and can decode up to 16 channels at 1,080p. To achieve comparable performance, PC-based solutions require more expensive CPUs to accommodate the processing demands.
Environment-Friendly
The power consumption of an average embedded NVR is 70 Watts, which is less than a regular light bulb. In comparison, the average power consumption of a PC running an NVR is about 250 Watts.
Repair Process
Sending back faulty hardware through a manufacturer's return merchandise authorization (RMA) is costly, time-consuming and oftentimes frustrating. For mission-critical applications, extra hardware expenditure must be allocated for spares in order to eliminate down time. Another option is to look for NVRs that have VMS preloaded in the disk-on-module (DOM) chip. This way, instead of shipping the whole machine back, only the small DOM needs to be replaced, suggested Sara Lin, VP of Instek Digital. "Our NVRs can be equipped with a powerful DOM, which contains Linux operating system and management software."
Other Considerations
Perhaps choosing the right systems integrator (SI) is just as important as deciding between DVRs and NVRs. Common belief is that SIs with IT background have a distinct advantage over SIs without sufficient IT or network background, for they are thought to be able to offer better service and support. “Many SIs also act as the platform developer and provider, and because they have more experience in platform development, many times they can meet customer requirements in a shorter time frame,” Wang said. Solution developers now put more investment in software and services, transforming themselves from merely product providers to total solution providers.
"When choosing an SI for surveillance projects, it is important to look for a balanced level of knowledge with regards to surveillance and IT systems," Iida said. "In addition, we believe offering better service and support is part of the value and identity of SIs."
