When you are down to a real buy decision, the question is not whether you need a Gigabit Ethernet Switch. The question is which switch reduces install friction, preserves spare capacity, and avoids an avoidable second purchase six months later. For US system integrators, panel builders, procurement teams, and electrical engineers comparing ONV-H3016 and ONV-H3024, the choice usually comes down to port density, cabinet space, growth headroom, and how much non-blocking throughput margin you want in a plug-and-play deployment.
Both models are unmanaged 16-port/24-port Gigabit Ethernet Switch options with fanless metal housing, AC100-240V input, LED indicator status visibility, low power consumption, and certifications listed in the model documentation. Both are positioned for security monitoring, hotel, campus, and small-business style networks. But they are not interchangeable once real node counts, rack plans, and RFQ risk are on the table.
Quick answer
Choose ONV-H3016 when your design is already disciplined around a smaller edge count, your cabinet is tighter, and you want a lower-port-count unmanaged switch that still delivers non-blocking wire-speed forwarding and plug and play deployment. Choose ONV-H3024 when growth, spare port policy, or denser aggregation matter more than the modest increase in size and power draw.
The buying mistake usually happens when teams size only to day-one endpoints and ignore recorder, uplink, service, and spare-port requirements. In a BoFu decision, the right model fits the current bill of materials and the next likely expansion event.
When ONV-H3016 is the better fit
ONV-H3016 is the better choice when your network plan is genuinely small to mid-density and you do not want to pay for unused copper ports. Its 16 data ports are often enough for smaller camera groups, recorder support, a local workstation, and a few spare points without forcing the physical width and density of a 24-port unit into the design.
It is also the cleaner fit when cabinet width and serviceability matter. With a listed size of 270 × 181 × 44.5 mm, ONV-H3016 is easier to position in tighter installations where panel builders are already juggling power entry, cable bend radius, DIN-rail equipment, and service clearance. If your project has a constrained build envelope, this smaller footprint can translate into easier airflow planning and less crowded cable routing.
Performance is still fully serious for this class. ONV-H3016 delivers 32Gbps switching capacity, 23.81Mpps forwarding at 64-byte packets, an 8K MAC table, and 4.1M of large buffer memory. That is enough for many day-one surveillance and mixed office edge loads without stepping into a larger chassis just for the sake of optics. If your install count is disciplined and your growth expectation is modest, ONV-H3016 is usually the more efficient buy.
The listed 15W power/input figure and full-load consumption below 15W also help when smaller cabinet power budgets are part of the review. If the project includes other control hardware, pair the switch decision with TPS ELECTRIC LLC resources on 24V DIN-rail power supplies and build-to-print control panels.
When ONV-H3024 is the better fit
ONV-H3024 wins when the job is port-dense today or when expansion is almost certain. That usually means larger surveillance groups, mixed-device floors, shared user/device zones, or projects where procurement would rather approve one slightly larger switch now than absorb another hardware event later.
The jump from 16 to 24 ports changes the install story. Those eight additional ports can cover recorder connections, maintenance devices, uplink reserve, and future node additions without requiring a second switch. ONV-H3024 also steps up to 48Gbps switching capacity and 35.71Mpps forwarding, giving more concurrency margin across denser endpoint sets.
Its listed size of 330 × 204 × 44 mm and net weight of 1.4 kg are still practical for desktop/wall mount/1U cabinet installation, but the model feels most natural where a 1U shelf or 19-inch cabinet plan already exists. If the broader project includes enclosure fabrication, cable routing, or mixed manufacturing support, the following TPS ELECTRIC LLC resources are especially relevant: electronic manufacturing services and mixed-technology PCB assembly.
Spec-by-spec comparison for procurement and engineering teams
| Key item | ONV-H3016 | ONV-H3024 | What it means in practice |
|---|---|---|---|
| Port count | 16 × 10/100/1000Base-T RJ45 | 24 × 10/100/1000Base-T RJ45 | Pick the model that still leaves meaningful spare ports after recorder, uplink, and service reserve. |
| Switching capacity | 32Gbps | 48Gbps | Both are non-blocking; the 24-port model gives more aggregate headroom as density rises. |
| Forwarding rate (64-byte) | 23.81Mpps | 35.71Mpps | Important when procurement wants a concrete performance number instead of only a marketing phrase. |
| Buffer memory | 4.1M | 4.1M | Helps with bursty traffic patterns and steady video transfer behavior. |
| Power / input | 15W / AC100-240V | 18W / AC100-240V | Both support standard global AC input without an external brick. |
| Housing and cooling | Fanless metal housing | Fanless metal housing | Fewer moving parts, quieter install, better fit for clean cabinet builds. |
| Protection / compliance | IP30, 4kV, CCC/CE/FCC/RoHS | IP30, 4kV, CCC/CE/FCC/RoHS | Supports fit-check conversations, but always match documentation to customer approval needs. |
| Warranty | 1-year warranty, lifelong maintenance | 1-year warranty, lifelong maintenance | Useful for after-sales and service planning. |
This is not a choice between “good” and “better.” It is a choice between “appropriately sized” and “appropriately sized with more growth room.” For procurement, the cleanest RFQ language is current port count, spare requirement, installation method, power input preference, and required compliance paperwork.
Deployment scenarios for CCTV, user devices, and panel-integrated builds
The application concept shown in the model literature is straightforward and useful: cameras, wireless access, user devices, printers, NVR, and monitor all aggregating through the switch. That is exactly why these models make sense in real projects. They solve the common edge-network problem without making the install team pay the complexity tax of a managed platform when the scope does not require it.
CCTV and security monitoring
For security monitoring, ONV-H3016 is typically enough for smaller camera groups or zone-level segmentation where one recorder and a few non-camera nodes share the same local switch. ONV-H3024 becomes the safer choice when the site wants more camera density at one point of aggregation or where future camera additions are already being discussed during bidding.
Control panel and cabinet builds
In control-panel or cabinet-integrated projects, the switch choice should never be isolated from the enclosure plan. Cable routing, field service access, AC entry, and physical mounting all affect how easy the finished assembly is to build and maintain. That is why switch selection should be reviewed alongside TPS ELECTRIC LLC guidance on industrial control cabinets, powder coating for electrical enclosures, and custom sheet metal enclosure design.
Hotels, campuses, and small business edge networks
For hotels, campuses, and SMB edge deployments, stable branch-like zones often justify ONV-H3016, while mixed-use or expansion-prone zones usually justify ONV-H3024.
Procurement and RFQ checklist before you place the order
If you are already at the buy stage, use this checklist to keep the RFQ clean and reduce back-and-forth between engineering and purchasing.
Authority references can help during approval discussions. The FCC eCFR text for Part 15 Class B explains the user-information language associated with Class B digital devices. The European Commission pages on CE marking and RoHS are useful for understanding the regulatory framework behind those labels, while the IEC overview for IEC 62368-1 summarizes the safety standard focus on safeguards and energy-source classification. These references are not substitutes for project documentation, but they are good procurement-side background.
If the switch sits inside a larger integration package, it also helps to review TPS ELECTRIC LLC resources on US compliance selection and switching DC power supply selection.
Final recommendation
Buy ONV-H3016 when your deployment is smaller, your cabinet is tighter, and your growth model is controlled. Buy ONV-H3024 when the node count is already dense or when expansion is likely enough that spare ports are cheaper than a future retrofit.
For most BoFu buyers, the safest rule is simple: if your real port plan is already pushing the mid-teens once recorder, uplink, and spare capacity are included, move to ONV-H3024 now. If your network is clearly below that threshold and physical compactness matters, ONV-H3016 is the sharper fit.

FAQ
Is ONV-H3016 enough for a typical small CCTV project?
Yes, when the camera count is modest and you still have ports left for an NVR connection, service access, and at least a few spares. It is the better fit when density is controlled and cabinet compactness matters.
When should I move up to ONV-H3024 instead of staying with 16 ports?
Move up when your endpoint count is already approaching the mid-teens after including recorder, uplink, and maintenance reserve, or when the customer is likely to add more devices after handover.
Do these switches require configuration before deployment?
No. Both models are unmanaged and positioned as plug-and-play switches, which is useful for projects that need fast install and simple turnover.
What mounting styles do these switches support?
The model documentation lists desktop, wall mount, and 1U/19-inch cabinet installation, making them flexible for racks, shallow cabinets, and bench-style deployment.
What compliance items are relevant for procurement teams?
The model documentation lists CCC, CE, FCC, and RoHS, along with a 1-year warranty and lifelong maintenance. For formal purchasing, request the exact compliance documents needed for your market and customer approval flow.
