A three-brand CCTV budget comparison is incomplete when one quote stores a month of footage and another stores only a week. Set the same recording policy and calculate usable capacity for the Seetong-compatible, Hikvision and Dahua options. Then compare the supported recorder and disk arrangements, keeping retention requirements separate from camera price.
Section 01
Agree the Recording Policy
A three-brand CCTV budget comparison is incomplete when one quote stores a month of footage and another stores only a week. Set the same recording policy and calculate usable capacity for the Seetong-compatible, Hikvision and Dahua options. Then compare the supported recorder and disk arrangements, keeping retention requirements separate from camera price. What must be fixed before comparing disk quotations? Fix which streams are recorded, their planned rates, the recording schedule and the required retention period. If event-only recording is proposed, describe that policy separately rather than treating it as equivalent to continuous recording. Different policies can produce very different capacity needs.
For agree the recording policy, build a working record around Recording policy baseline. For Seetong Hikvision Dahua storage budget, record the current project condition, candidate response, evidence source and unresolved boundary before comparing offers.
Review Recording policy baseline separately from the downstream workflow. This prevents one attractive specification from deciding the complete Seetong Hikvision Dahua storage budget question without considering recording, installation, operation and support consequences.
Carry the Recording policy baseline record into the RFQ, BOQ review or pilot checklist. For Seetong Hikvision Dahua storage budget, keep product capability, project assumptions and supplier responsibility beside the agree the recording policy decision; site measurements, network policy, installation safety and acceptance remain project inputs unless the signed scope says otherwise.
- Record recording policy baseline with a named source, owner or acceptance check; do not leave it as an unqualified brochure phrase.

Section 02
Calculate the Three Retention Cases
How can a 32-camera planning example be compared? Assuming 32 continuous streams at an average 4 Mbps each, recorded data is 41.472 decimal TB for 30 days, 82.944 TB for 60 days and 124.416 TB for 90 days. These are arithmetic examples, not measured performance or a mandatory retention policy.
For calculate the three retention cases, build a working record around 30, 60, 90-day data table. For Seetong Hikvision Dahua storage budget, record the current project condition, candidate response, evidence source and unresolved boundary before comparing offers.
Review 30 and 60 separately from 90-day data table. This prevents one attractive specification from deciding the complete Seetong Hikvision Dahua storage budget question without considering recording, installation, operation and support consequences.
Carry the 30/60/90-day data table record into the RFQ, BOQ review or pilot checklist. For Seetong Hikvision Dahua storage budget, keep product capability, project assumptions and supplier responsibility beside the calculate the three retention cases decision; site measurements, network policy, installation safety and acceptance remain project inputs unless the signed scope says otherwise.
- Record 30 with a named source, owner or acceptance check; do not leave it as an unqualified brochure phrase.
- Verify 60 with a named source, owner or acceptance check; do not leave it as an unqualified brochure phrase.
- Compare 90-day data table with a named source, owner or acceptance check; do not leave it as an unqualified brochure phrase.
Section 03
Apply a Clear Capacity Allowance
Is reserving 20 percent the same as multiplying by 1.2? No. If recorded data may occupy at most 80 percent of usable capacity, divide the data requirement by 0.8. That is a different rule from adding 20 percent to the data estimate. State the chosen policy so all quotations use the same interpretation.
For apply a clear capacity allowance, build a working record around Utilization allowance worksheet. For Seetong Hikvision Dahua storage budget, record the current project condition, candidate response, evidence source and unresolved boundary before comparing offers.
Review Utilization allowance worksheet separately from the downstream workflow. This prevents one attractive specification from deciding the complete Seetong Hikvision Dahua storage budget question without considering recording, installation, operation and support consequences.
Carry the Utilization allowance worksheet record into the RFQ, BOQ review or pilot checklist. For Seetong Hikvision Dahua storage budget, keep product capability, project assumptions and supplier responsibility beside the apply a clear capacity allowance decision; site measurements, network policy, installation safety and acceptance remain project inputs unless the signed scope says otherwise.
- Record utilization allowance worksheet with a named source, owner or acceptance check; do not leave it as an unqualified brochure phrase.
| Comparison factor | Object or condition | Evidence-led action | Do not infer |
|---|---|---|---|
| 30 days | 41.472 TB recorded data | 51.840 TB usable target at 80% | Illustrative 32 × 4 Mbps |
| 60 days | 82.944 TB recorded data | 103.680 TB usable target at 80% | No RAID overhead included |
| 90 days | 124.416 TB recorded data | 155.520 TB usable target at 80% | Not a legal retention recommendation |
| Physical disks | Use exact NVR compatibility | Separate raw and usable | No unverified SKU combination |

Section 04
Match the Physical Disk Arrangement
What remains after calculating required usable capacity? Check supported disk sizes, bay count, any supported RAID layout and other capacity overheads for the exact recorder. A raw disk total does not establish the usable amount. Do not recommend a physical combination until its capacity and compatibility match the requirement.
For match the physical disk arrangement, build a working record around Disk configuration table. For Seetong Hikvision Dahua storage budget, record the current project condition, candidate response, evidence source and unresolved boundary before comparing offers.
Review Disk configuration table separately from the downstream workflow. This prevents one attractive specification from deciding the complete Seetong Hikvision Dahua storage budget question without considering recording, installation, operation and support consequences.
Carry the Disk configuration table record into the RFQ, BOQ review or pilot checklist. For Seetong Hikvision Dahua storage budget, keep product capability, project assumptions and supplier responsibility beside the match the physical disk arrangement decision; site measurements, network policy, installation safety and acceptance remain project inputs unless the signed scope says otherwise.
- Record disk configuration table with a named source, owner or acceptance check; do not leave it as an unqualified brochure phrase.
Section 05
Separate Retention from Event Archives
Does longer NVR retention replace a separate event archive? Not necessarily. Routine overwrite retention and keeping selected incident exports are different requirements. Define the events that need preservation and how they are retrieved, stored and accessed. Include any required archive resources separately rather than assuming a larger NVR solves every evidence-handling task.
For separate retention from event archives, build a working record around Retention, archive scope. For Seetong Hikvision Dahua storage budget, record the current project condition, candidate response, evidence source and unresolved boundary before comparing offers.
Review Retention and archive scope separately from the downstream workflow. This prevents one attractive specification from deciding the complete Seetong Hikvision Dahua storage budget question without considering recording, installation, operation and support consequences.
Carry the Retention/archive scope record into the RFQ, BOQ review or pilot checklist. For Seetong Hikvision Dahua storage budget, keep product capability, project assumptions and supplier responsibility beside the separate retention from event archives decision; site measurements, network policy, installation safety and acceptance remain project inputs unless the signed scope says otherwise.
- Record retention with a named source, owner or acceptance check; do not leave it as an unqualified brochure phrase.
- Verify archive scope with a named source, owner or acceptance check; do not leave it as an unqualified brochure phrase.

Section 06
Compare Cost at the Same Retention
What makes a low-cost Seetong recorder package credible? A documented ability to support the selected streams, the required usable disk arrangement and the intended retrieval tasks. Compare that package at the same retention policy as the Hikvision and Dahua options. A lower price achieved by silently reducing recording days is not an equivalent value offer.
For compare cost at the same retention, build a working record around Retention-normalized comparison. For Seetong Hikvision Dahua storage budget, record the current project condition, candidate response, evidence source and unresolved boundary before comparing offers.
Review Retention-normalized comparison separately from the downstream workflow. This prevents one attractive specification from deciding the complete Seetong Hikvision Dahua storage budget question without considering recording, installation, operation and support consequences.
Carry the Retention-normalized comparison record into the RFQ, BOQ review or pilot checklist. For Seetong Hikvision Dahua storage budget, keep product capability, project assumptions and supplier responsibility beside the compare cost at the same retention decision; site measurements, network policy, installation safety and acceptance remain project inputs unless the signed scope says otherwise.
What should the buyer include in an RFQ for Seetong Hikvision Dahua storage budget? Provide the camera schedule, required workflows, candidate equipment lists, mandatory brand or integration constraints, and the evidence still needed for compare cost at the same retention. Keep access credentials out of the inquiry. For Seetong Hikvision Dahua storage budget, this defines the next comparison; it does not promise identical performance, fixed savings or automatic approval.
- Record retention-normalized comparison with a named source, owner or acceptance check; do not leave it as an unqualified brochure phrase.
