Determining the amount of storage needed for video surveillance can be influenced by several factors. These include the resolution of your cameras, the number of cameras you have, how much footage you need to store, and whether you're recording continuously or only when motion is detected.
Why Should You Care About Video Surveillance Storage? 🎥
Simply put, the more storage you have, the more footage you can keep. This can be crucial in situations where you need to review incidents that occurred several days or even weeks ago. Without enough storage, old footage will get overwritten by new footage, potentially causing you to lose important evidence.
What's Eating Up Your CCTV Storage Capacity? 🧐
How Camera Resolution Impacts Your Storage 📈
The resolution of your camera significantly impacts how much storage your video surveillance system will need. Higher resolution cameras produce better quality images but also require more storage space. For example, a 1080p camera will need more storage than a 720p camera.
More Cameras, More Storage: Here's Why 📹
The more cameras you have in your surveillance system, the more storage you will need. Each camera adds to the total amount of footage being recorded and stored.
Recording 24/7 or Motion-Triggered: What's Best for Your Storage? ⏰
Are you recording 24/7, or only when motion is detected? Continuous recording ensures that you capture everything, but it uses more storage. On the other hand, recording only when motion is detected can conserve storage, but you may miss important events.
How Long Should You Keep Your Footage? 📅
How long do you need to keep your footage? A week? A month? The longer you need to keep your footage, the more storage you will need.
Let's Do the Math: Calculating Your Surveillance Storage Needs 🧮
Now that we know what factors into the storage needs, let's look at how you can calculate your specific requirements. You can use a surveillance camera storage calculator to get an estimate of the storage you'll need. You'll need to input the resolution of your cameras, the number of cameras, your recording schedule, and the retention period.
To help you estimate your storage needs for your video surveillance system, use the calculator below.

Please note that this is an estimate. Actual storage needs may vary based on factors such as the specific camera model, the complexity of the scene being recorded, and the video compression used.
As a general rule of thumb, for one camera recording continuously at 1080p resolution, you'll need approximately 60GB of storage per day. So, if you have four cameras, you'll need about 240GB per day. If you want to keep your footage for a week, you'll need approximately 1.68TB of storage.
Choosing Your Champion: Best Storage Solutions for Security Cameras 🏆
There are several options for storing your surveillance footage. You can use a Network Video Recorder (NVR), a Digital Video Recorder (DVR), or cloud storage. The best option depends on your specific needs and circumstances.
Top Storage Solutions for Video Surveillance
- Network Video Recorder (NVR): This device is connected to your network and records video footage from your IP cameras. NVRs offer high-quality footage and are ideal for systems with a large number of cameras.
- Digital Video Recorder (DVR): DVRs are connected directly to your surveillance cameras via coaxial cables. They are a cost-effective solution, but the video quality may not be as high as with NVRs.
- Cloud Storage: This option allows you to store your surveillance footage on a remote server. Cloud storage offers the advantage of accessibility from anywhere, but recurring subscription costs can add up.
- External Hard Drive: An external hard drive can be a good option for smaller systems or for short-term storage. They are portable and easy to use, but may not offer the same level of security as other options.
- SD Card: Some surveillance cameras have built-in SD card slots for local storage. This can be a convenient and cost-effective solution, but storage capacity is limited.
When choosing a storage solution, consider the cost, ease of use, capacity, and security. Cloud storage, for example, is easy to use and can provide virtually unlimited storage, but it typically requires a monthly subscription. On the other hand, NVRs and DVRs are one-time purchases, but they have limited storage capacity and can be more difficult to set up and manage.
Comparison of NVR, DVR, and Cloud Storage for Video Surveillance
Let's have a closer look at the three main types of storage solutions - NVR, DVR, and Cloud Storage. Here's a comparison table to help you understand the differences and similarities:
| Storage Type | Cost | Ease of Use | Capacity | Security |
|---|---|---|---|---|
| NVR | One-time purchase, higher upfront cost | Can be difficult to set up and manage | Limited, depends on the hard drive size | High, stored locally, less prone to hacking |
| DVR | One-time purchase, lower upfront cost than NVR | Can be difficult to set up and manage | Limited, depends on the hard drive size | High, stored locally, less prone to hacking |
| Cloud Storage | Monthly subscription, cost varies | Easy to use, accessible from anywhere | Virtually unlimited | Depends on the provider, potential for hacking |
As you can see, each storage solution has its own strengths and weaknesses. Your choice will depend on your specific needs, budget, and technical capabilities.
