Achieve up to 45% energy savings with eDVRs

Around the world, energy costs have been rising and the need to lower carbon emissions is more pressing than ever. With Hikvision’s range of eDVRs, homeowners and businesses can achieve annual, per-device energy savings of 40-45 kWh compared to traditional DVRs – the equivalent to more than 3000 iPhone charges.

Traditional digital video recorders (DVRs) consume a significant amount of power due to their reliance on hard disk drives (HDDs). These drives are comprised of numerous moving parts, such as spindles, actuator arms, and drive heads, which contribute to high energy consumption for data storage.

Reducing power consumption for DVRs

To address this challenge, and to help organisations and individuals reduce their energy costs and emissions, Hikvision has created a range of new eDVRs. These use embedded solid state drive (eSSD) technology rather than traditional HDDs, which eliminates the need for moving parts in the storage drive, delivering major improvements in energy efficiency.

The eSSDs incorporate a highly integrated NAND and a solid-state controller, which offer improved memory capacity, heat dissipation, and overall electrical performance compared with traditional HDDs.

How much greener?

In an in-house lab test, Hikvision has found that the energy consumption of the eSSD storage chip for the DS-E04HQHI-B model is 0.4-0.5 Watts. This is 10 times more energy efficient than the 4.0-5.0 Watts demanded by the more traditional technology.

When considering the green performance of the devices as a whole, eDVRs with eSSD storage are around 45% more energy efficient than traditional eDVRs. The new eDVRs register a power consumption of 5.42-5.82 Watts, rather than the 9.48-11.00 Watts that traditional DVRs use to perform a similar function (albeit with lower performance).

These tests show that replacing traditional DVRs with Hikvision eDVRs could save typical homeowners and small businesses up to 45 Kilowatt-Hours (kWh) of electricity per year, per device. In a time of energy cost and supply uncertainties, Hikvision eDVRs can help in terms of reducing costs and carbon emissions.

As well as offering major energy savings, Hikvision’s new eDVRs are more sustainable for a number of other reasons.

Firstly, by eliminating moving parts from the storage drive, eSSD technology reduces internal wear and tear in the eDVR, and extends the product’s useful lifecycle. This optimises customers’ investments in Hikvision technology and reduces carbon emissions related to replacing end-of-life equipment.

Secondly, the highly compact nature of the eSSD chips means that the new Hikvision eDVRs are smaller than traditional DVR devices. This reduces shipping costs and packaging requirements, and all the related environmental impacts.

Finally, Hikvision uses green packaging for the new eDVRs instead of conventional plastic packaging and EPE foam. This ensures that waste is minimised across the entire delivery chain.

eDVR energy savings in numbers

• Accounts for only 10% of power consumption of a traditional HDD.

• Typical energy consumption per eDVR of 5.42-5.82 Watts (for model DS-E04HQHI-B), compared with

9.48-11.00 Watts for traditional DVRs.

• Per-device energy savings of 40-45 kWh per year (equal to 3000 iPhone charges).

• Sustainability beyond energy efficiency.
