Comparing HiLook DVR 204Q-M1 vs. DVR 204Q-K1

Comparing HiLook DVR 204Q-M1 vs. DVR 204Q-K1

When selecting a Digital Video Recorder (DVR) for your security system, it is essential to understand the specific features and capabilities of each model to make an informed decision. Two popular models from HiLook, a sub-brand of Hikvision, are the DVR 204QM1 and the DVR 204QK1. Here is a detailed comparison to help you understand the differences between these two models.

1. Basic Specifications 

DVR 204QM1:

  • Channels: 4
  • Video Compression: H.264
  • Recording Resolution: Up to 1080p
  • HDMI and VGA output: Up to 1080p resolution
  • Storage: Supports 1 SATA HDD up to 6TB
  • Network: 1 RJ45 10M/100M Ethernet interface

DVR 204QK1:
  • Channels: 4
  • Video Compression: H.265+/H.265
  • Recording Resolution: Up to 1080p
  • HDMI and VGA output: Up to 1080p resolution
  • Storage: Supports 1 SATA HDD up to 6TB
  • Network: 1 RJ45 10M/100M Ethernet interface

    2. Video Compression

    One of the most significant differences between the DVR 204QM1 and the DVR 204QK1 is the video compression technology used:

    DVR 204QM1 uses H.264 compression:

    • H.264 is a widely used video compression standard that offers good video quality at a variety of bit rates.
    • It requires more storage space compared to newer compression formats.
    DVR 204QK1 uses H.265+/H.265 compression:
    • H.265 (also known as HEVC) offers approximately double the data compression ratio at the same level of video quality or substantially improved video quality at the same bit rate compared to H.264.
    • H.265+ is an optimized version of H.265 that further reduces the bit rate and storage requirements.
    • This results in more efficient storage usage and better performance in terms of bandwidth.

      3. Storage and Network

      Both models support a single SATA HDD up to 6TB and have the same network interface, ensuring they can handle similar amounts of data and network traffic. However, the more efficient video compression of the DVR 204QK1 can result in longer storage durations and reduced bandwidth usage.

      4. Performance and Efficiency

      DVR 204QM1: Suitable for basic surveillance needs where H.264 compression is sufficient, and storage or bandwidth efficiency is not a primary concern.


      DVR 204QK1: Better suited for scenarios requiring higher efficiency in storage and bandwidth usage due to its advanced H.265+/H.265 compression. This makes it ideal for environments with limited storage capacity or where higher quality recordings are necessary over extended periods.

        5. Cost

        The DVR 204QK1 might be slightly more expensive than the DVR 204QM1 due to its advanced features and more efficient compression technology. However, the long-term savings in storage and bandwidth could justify the higher initial cost.

        Conclusion

        Choosing between the HiLook DVR 204QM1 and DVR 204QK1 depends on your specific needs. If you require efficient storage and bandwidth usage with better video quality, the DVR 204QK1 is the superior choice. However, if you are looking for a cost-effective solution for basic surveillance requirements, the DVR 204QM1 will suffice. Understanding these differences ensures you select the right DVR model that fits your security system needs and budget.
