Alarm Grid Now Offers a MicroSD Card Made For Video Use

Alarm.com announced last week that it would begin offering a MicroSD card for use with its cameras that is made by Western Digital. Prior to that time, they offered a card manufactured by Micron. The WD Purple MicroSD card offers a lower price point and higher endurance performance.

The Alarm.com ADC-USD-256GB-WD MicroSD card is designed by Western Digital specifically for the mainstream video market. It offers an excellent balance of price, endurance, capacity, and longevity. This card is being offered by Alarm.com, but it can be used in any video camera that supports the use of a MicroSD card, either for backup, in the event the camera loses its network connection, or for primary recording, such as with the Alarm.com Onboard Recording and Smart View feature.

Alarm.com cameras only support card capacities up to 256GB, which is, I'm sure, why they've chosen to sell only cards with the 256GB capacity. Western Digital actually makes the WD Purple MicroSD cards in capacities from 32 GB to 1TB, as you can see from their Data Sheet. Currently, Alarm Grid is only offering the 256GB capacity cards that are offered through Alarm.com.

The WD Purple MicroSD cards use advanced 96-Layer 3D NAND technology. What this means is that there are 96 layers of NAND Flash memory medium stacked together, forming a 3D shape, sort of like a 96 story skyscraper, but very tiny. There are vertical channels between the layers, allowing communication between them. This architecture allows for less power consumption, greater storage capacity, greater endurance, and the ability to operate in temperatures ranging from -13℉ - +185℉ (-25℃ - +85℃). It also makes them humidity resistant, so they're great for working both indoors and outdoors.

Another feature of these MicroSD cards that makes them perfect for video surveillance use is the Card Health Monitoring feature. With compatible cameras, the camera can send a notification when it's time to replace the card. We're unsure if the Alarm.com cameras support this feature, but we have a request into them to check, and will update this post with the answer.

Update: Per Alarm.com CORE Technical Support, the Alarm.com cameras do not support the Card Health Monitoring feature at this time, but may begin supporting it in the future.

What are you thoughts on this subject? Do you have a camera that supports a higher capacity MicroSD card that you would like to see us offer for sale? Leave a comment below, and if there's interest, we can check into offering these cards in other capacities. Until then, have a great week, and we'll see you soon. Stay safe!
