Operating from Bendigo and serving Ballarat, Geelong, Melbourne and surrounding Central Victoria, HiVizz Security is an owner‑operated installer of 4K CCTV systems that provides free on‑site quotes for residential and small‑business customers. An NVR (Network Video Recorder) is a dedicated device that stores and manages CCTV video footage.
Understanding What Determines Retention Days
The length of time you can keep footage comes down to four things:
- Number of cameras – each extra camera adds data, depending on its resolution and frame rate.
- Resolution – 4K video eats up more space than 1080p.
- Frame rate (fps) – higher fps gives smoother video but uses more megabytes.
- Drive size – the capacity of your surveillance‑rated HDD or SSD sets the hard limit.
Multiply cameras × resolution × frame rate × drive size and you get a rough idea of how many days of video you’ll have. For a typical Bendigo home with four 4K cameras recording at 15 fps, a 4 TB drive stores about 30 days of motion‑triggered footage, whereas four 1080p cameras on motion recording can easily exceed 90 days [INDEX: 3, 5].
Continuous Recording vs. Motion‑Triggered Recording
Continuous (24/7) recording captures every second and can need three‑to‑four times the space of motion‑only recording. Motion‑triggered recording only saves video when movement is detected, stretching the same drive’s retention by two‑to‑four times.
A few tips to get useful footage:
- Define motion zones that cover entry points (front door, driveway, garage) and ignore static areas (garden wall).
- Pick a sensible sensitivity – too high and you’ll record every passing bird; too low and you might miss a break‑in.
- Keep one “critical” camera (e.g., front door) on continuous mode and set the rest to motion‑only for a balanced setup.
Choosing the Right Drive: Surveillance‑Rated HDDs
We recommend surveillance‑rated drives (e.g., “WD Purple” or “Seagate SkyHawk”) because they’re built for 24/7 write cycles and tend to fail less often than consumer drives.
- 4 TB surveillance drive – roughly 30 days of motion‑triggered 4K footage from four cameras.
- 8 TB drive – about double the capacity, handy for larger homes or longer retention without swapping drives.
All drives we supply come with a 2-year warranty on products and a 1-year warranty on workmanship.
Cloud vs. Local Storage – What’s Best for Homeowners?
Many homeowners use a hybrid approach: store the most recent 30 days on the local NVR and archive older clips to inexpensive cloud storage for long‑term safekeeping.
| Feature | Local NVR (HiVizz) | Cloud Backup |
|---|---|---|
| Access | Instant playback via the HiVizz mobile app – no monthly fee | Web portal; may incur subscription costs |
| Reliability | Works even if the internet drops | Off‑site redundancy protects against theft or fire |
| Cost | One‑off hardware cost; no recurring fees | Ongoing monthly or annual fees |
| Control | Full control over retention settings | Provider may set limits on storage length |
Quick NVR Retention Calculator (Simple Table)
Use this table as a starting point and adjust the numbers to match your camera specs and frame rate.
| Setup (Resolution / FPS) | Cameras | Recording Mode | Drive Size | Approx. Retention |
|---|---|---|---|---|
| 4 K / 15 fps | 4 | Motion‑only | 4 TB | ~30 days |
| 1080p / 15 fps | 4 | Continuous | 2 TB | ~15 days |
| 4 K / 30 fps | 2 | Continuous | 4 TB | ~10 days |
Legal & Privacy Best Practices in Victoria
There’s no statutory minimum or maximum retention period for private home CCTV in Victoria, as the Privacy Act 1988 (Cth) and Australian Privacy Principles do not apply to domestic security cameras operated in a private capacity [INDEX: 1, 4]. However, industry best practice advises keeping footage no longer than necessary – usually 30‑90 days.
- Consider putting clear warning signage at entry points as an optional security best practice and deterrent, although warning signs are not legally mandated for private residential properties under Victoria's Surveillance Devices Act 1999 (Vic) [INDEX: 0, 2].
- Store footage securely and limit access to authorised household members.
- We can configure your NVR’s retention settings to line up with these best-practice guidelines.
FAQ – Common Questions About CCTV Retention
Q: Do I have to keep footage for a set number of days? A: No law forces a specific retention period for private residential CCTV, as federal privacy laws do not cover domestic setups [INDEX: 1, 4]. Industry best practice suggests keeping footage only as long as it’s needed – typically between 30 and 90 days.
Q: How can I check how much storage my NVR is using? A: Most NVR interfaces, including the HiVizz mobile app, show a real‑time storage utilisation bar. You can also log into the NVR’s web dashboard and view the “Disk Usage” page for exact figures.
Q: Can I extend retention without buying a new drive? A: Yes. Switching from continuous to motion‑triggered recording, lowering the frame rate, or dropping the resolution on less‑critical cameras can double or even triple the number of days you keep footage on the same drive.
Q: What type of cameras do you recommend for a 4K home system? A: We favour reputable 4K models from Hikvision and Dahua. Both work smoothly with our NVRs, perform well in low light, and support PoE (Power over Ethernet) for tidy installations.
Q: Is there a warranty on the equipment and installation? A: We offer a 2-year warranty on products and a 1-year warranty on workmanship.
