What Is A MicroSD Card?

Memory cards are used to expand the storage of your device. Calling memory cards, and SD card is not preferable as there are various types of cards that offer different sizes and applications.

The standard dimensions for microSD cards are 15 mm x 11 mm x 1 mm, hence it would be wrong to call them all under the same name, SD cards.

In addition, the design of the memory card hasn’t altered all that much during its existence. Mostly, the changes have been internal like the size.

Unlike SD cards, MicroSD or TF cards offer a maximum of 512GB storage, mainly because of the volume.

Having a lot on your plate to ponder upon, we have created a comprehensive guide to walk you through the process of choosing the best microSD cards for outdoor and indoor security cameras.

How To Choose Micro SD Card For Security Camera

Acquiring the most appropriate memory card for your camera might be a time-consuming endeavor.

Different surveillance systems have different storage capacity and compatibility requirements along with security camera applications and a plethora of different brands fighting for your attention; Which one should I pick?

Capacity

Memory cards come in a variety of storage capacities, also known as the size of memory cards.

Ranging from 16GB to 32GB, 64GB, 128GB, and even 256GB memory cards, you can get enough storage space to meet your IP security cameras’ storage needs.

Moreover, there are a few other factors to consider, including;

  • Checking your camera’s specifications is the first step while looking for the best SD card. It is because some cameras have limited maximum storage.
  • Figure out how much storage space you’ll need depending on your security camera’s intended purpose. If your camera is set to record continuously, you should choose a memory card with a larger capacity. If you only wish to use your memory card as a backup storage device, you can get away with a lower capacity.
  • Finally, consider your camera’s resolution because higher-resolution video footage uses up more storage space. Hence, choose a high-capacity memory card if your camera’s resolution is 1080p or 4K.
  • Lastly, you must consider video surveillance time in terms of capacity. Some outdoor cameras offer motion detection features that only start recording once the motion is detected. It means that the camera only records when there is any distress.

Speed

The SDHC speed rating is another important factor when it comes to choosing the best microSD card for your CCTV cameras.

Memory cards are rated according to their writing and reading speeds. Particularly for security and digital camera applications, however, only the write speed matters in comparison to reading speeds.

The write speed of a memory card refers to how quickly it writes (records) data to its memory. When using a slow microSD card, recorded movies may skip frames or become sluggish.

Unlike the capacity, however, most security cameras do not expressly provide high speeds.

The recommended write speed for a video surveillance memory card is usually a 10-speed rating of SDHC class, which implies it can write at least 10MBPS. 

In addition, SDHC is being phased out in favor of SDXC I and SDXC II, making the decision even more difficult. So, how do you pick the right second-write speed memory card?

In terms of the speed rating of memory cards, we recommend that you make your selection based on the resolution of your camera.

Here are some recommendations for speed class that you can make as per your security camera.

MicroSD cards with faster writing rates are required for cameras with better resolution;

  • MicroSD cards with a write speed of at least 30MB/second are recommended for 4K cameras. It is denoted with the number “3” inside a U-bracket, marked on the card.
  • Use a memory card with a write speed of at least 10MB/second for 1080p and 720p cameras. Such cards offer a quick transfer of larger files. SDHC Class 10, SDXC with the number “1” inside a U-bracket.

For quick and easy selection, refer to the table below.

Class SpeedUHS SpeedApplicationWrite Speed
C2 Standard Resolution2 mb/s
C4 720p/1080p4 mb/s
C6 720p/1080p6 mb/s
C10U120p/1080p, 4k10 mb/s
 U3720p/1080p, 4k @ 60/120fps30 mb/s
  720p/1080p, 4k, 8K @ 60/120fps60 mb/s
  720p/1080p, 4k, 8K @ 60/120fps90 mb/s

You can choose your MicroSD card depending on the specifications of your camera to make sure it offers compatibility.

Durability

It is a vital feature of all outdoor or indoor security cameras and like every other aspect, memory cards are significantly affected when they are exposed to harsh conditions.

In addition, the use of continuous recording can also ultimately harm the memory card if used indefinitely. Hence, the quality, price, and brand come into play at this point.

When durability comes into play, you must consider the fact that some cameras feature magnets, which potentially are not good for most micro SD cards.

In addition, water and temperature resistance is not just important, but crucial, particularly if you are going to use them in outdoor security cameras.

Good brands like Sandisk, Samsung, and Kingston can easily get you a 5-year warranty for their tested and approved SD cards.

Data Protection

Data protection is an issue, in addition to capacity and speed. Only a few Sd cards feature an Error Correction Code (ECC).

It enhances reliability by automatically identifying and correcting transfer faults. This is useful in any setting, but it’s particularly useful in situations when you need to work rapidly and give results in a limited amount of time.

Having a dependable card with a low probability of failure or mistakes is crucial when you need to upload, share,  or email files to other storage.
