Hikvision DS-7604NI-I1-4P 4ch PoE CCTV NVR 4K NO Hard Drive

Model: DS-7604NI-I1-4P (No HDD)

Who This Is For

For installers and property owners who need a compact, self-contained recording platform for up to 4 IP cameras without the clutter of separate power supplies. The Hikvision DS-7604NI-I1-4P is a 4-channel PoE NVR built for small commercial premises, residential installs, and light industrial sites where the camera count is defined and unlikely to grow beyond 4. Each of the 4 onboard IEEE 802.3af PoE ports powers a connected camera directly over Cat5e or Cat6, which keeps cable runs clean and commissioning time short. Recording runs at up to 8 MP (4K) per channel, and the single HDMI output drives a monitor at up to 3840 x 2160 for local live view and playback. Sold without a hard drive, this unit suits buyers sourcing their own preferred HDD or adding storage to an existing deployment.

What This NVR Actually Does

Who Buys This Model

• Small retail and cafe operators: Running 3-4 cameras over a ceiling or rear-of-house layout, where a single PoE NVR eliminates the need for a separate switch and power supplies at each camera drop.
• Residential installers fitting 4-camera systems: Specifying a dedicated 4-channel unit to match a defined camera count without paying for unused channels on a larger recorder.
• Strata and apartment common-area applications: Covering a foyer, car park entry, and 1-2 access corridors with 4K recording from a compact 1U unit that fits a small comms cabinet.
• IT integrators adding surveillance to an existing network: Sourcing the NVR body separately and installing a preferred surveillance-rated HDD rather than accepting a bundled drive.

Honest Assessment

The DS-7604NI-I1-4P does its core job well - it records 4 channels at up to 8 MP with genuine 4K HDMI output, powers cameras directly over PoE without a switch, and keeps installation straightforward. H.265+ compression is a practical advantage when working with a single HDD bay limited to 6 TB. The 40 Mbps incoming bandwidth comfortably handles 4 channels at high resolution simultaneously. Where this unit falls short: it has only 1 HDD bay and no capacity to add a second drive, so redundant storage or RAID is not an option. The 4-channel ceiling is fixed - if there is any likelihood of adding a 5th camera in future, a higher-channel NVR is a better investment now. Audio I/O is present via RCA but there is no built-in audio processing beyond input and output passthrough. Available through Security Australia, this NVR suits defined 4-camera deployments where the channel count is set and simplicity of install is the priority.

Before You Buy

Quick Fit Check

• Good match if: You are specifying a fixed 4-camera layout and want PoE delivered directly from the recorder - eliminating a separate switch and reducing the number of powered devices in your cabinet.
• Good match if: You need 4K recording and 4K local display from a compact 1U unit that fits a small network cabinet or shelf-mounted enclosure in a residential or light commercial install.
• You may need a different model if: Your camera count may grow beyond 4, you need dual-drive redundancy, or you are running cameras that require PoE+ power - in which case an 8-channel or higher NVR with PoE+ support would be more suitable.

Real-World Scenarios

How It Compares

• Choose this if: Your camera count is fixed at 4, you want PoE delivered directly from the recorder without a separate switch, and you need genuine 4K recording and display from a compact 1U unit.
• You may need a different model if: You anticipate adding more than 4 cameras at any point, or you need dual-drive storage redundancy - an 8-channel or higher NVR with multiple HDD bays would serve those requirements better.
• Pairs well with: IEEE 802.3af-compatible PoE IP cameras (turret, dome, or bullet type) rated up to 8 MP, plus a surveillance-class 3.5" SATA hard drive up to 6 TB.

Common Questions

1. Does this NVR come with a hard drive?

   No. The DS-7604NI-I1-4P is supplied without a hard drive. You will need to fit a surveillance-rated 3.5" SATA HDD separately. The unit supports a single drive up to 6 TB. Surveillance-class drives (rated for continuous 24/7 write cycles) are strongly recommended over standard desktop drives, which are not designed for the write load a recording NVR generates.

2. Will this NVR work with non-Hikvision IP cameras?

   Yes, with limitations. The NVR supports ONVIF-compatible third-party IP cameras, but full feature access - including smart recording triggers and remote health monitoring - is only available with Hikvision cameras. If you are running a mixed brand deployment, verify ONVIF profile compatibility before purchasing. The PoE ports will still supply IEEE 802.3af power to compatible third-party cameras.

3. Can I connect PTZ cameras to the onboard PoE ports?

   Only if the PTZ camera draws 15.4W or less. The 4 onboard PoE ports conform to IEEE 802.3af, which has a 15.4W per-port ceiling. Most PTZ cameras require IEEE 802.3at (PoE+, up to 30W). If you plan to use PTZ cameras on this NVR, they will need an external PoE+ injector or switch for power - the NVR will still handle the video stream over the network port, but cannot power the camera directly via its built-in PoE.

4. Does this NVR support remote viewing on a phone or computer?

   Yes. The DS-7604NI-I1-4P supports remote access via Hikvision's mobile app and desktop client software. Live view and recorded footage playback are both accessible remotely once the NVR is connected to your local network and remote access is configured. The NVR's 40 Mbps incoming bandwidth handles all 4 channels simultaneously, though your internet upload speed will determine the quality available for remote streams.

5. How much recording time will I get from a single hard drive?

   It depends on camera count, resolution, frame rate, and scene complexity. With H.265+ compression across 4 channels at 8 MP, a 4 TB surveillance drive typically yields roughly 2-4 weeks of continuous recording depending on bitrate settings and how much motion is in each scene. Reducing frame rate on low-activity channels or switching to motion-triggered recording after hours extends retention significantly. The team at Security Australia can help estimate storage requirements for specific camera and resolution combinations.

6. Does the 40 Mbps incoming bandwidth limit affect recording quality when all 4 cameras are running?

   No, for typical 4-camera 8 MP deployments. 4 channels at 8 MP and 25fps using H.265+ compression will normally consume well under 40 Mbps combined. The bandwidth ceiling only becomes relevant if cameras are configured for unusually high bitrates or if you attempt to connect higher-resolution cameras (such as 12 MP models) across all 4 channels simultaneously at maximum frame rates. The confirmed decoding spec of 4-ch at 8 MP and 25fps confirms headroom is adequate for standard 4K-per-channel operation.
