In security camera applications, only the write speed matters.
Choose a memory card with a speed rating of SDHC Class 10, which means it can sustain a write speed of at least 10MBPS. Making the choice even more complex, the SDHC speed rating is now being replaced by SDXC I and SDXC II.
For 4K cameras, look for microSD cards that can sustain a write speed of at least 30MB/second. Such cards are usually marked as SDXC I with the number “3” inside a U-bracket or SDXC II V30. For 1080 and 720p cameras, use a memory card that can sustain at least 10MB/second write speed. They are marked as SDHC Class 10, SDXC I with the number “1” inside a U-bracket, or SDXC II V10
Samsung PRO Endurance microSD cards were recently released. The best thing about them is that they are designed specifically for home security cameras.According to Samsung, they are waterproof (IP67), high-temperature resistant (up to 185℉), magnet-proof, and even X-ray proof. Finally, they are capable of recording for up to 43,800 hours straight (that’s 5 years), making them the perfect solution for video surveillance. Samsung PRO Endurance cards can maintain a write speed of up to 30MB/second, which is more than enough for 1080p and 720p recordings and just right for 4K recordings .
Operating Temperature
(-13°F to 185°F)
Non-operating Temperature
(-40°F to 185°F)
Has SDXC1 with "1" inside of U-Bracket
Samsung PRO+ However, it’s not designed for prolonged recording. Speed is its priority, but it’s not as durable as Samsung PRO Endurance.
Western Digital Purple MicroSD cards:
SDA 6.0 UHS-I interface (WD Purple microSD) Variety of endurance offerings and card health monitor for extended continuous recording
Operating temperature range: -25°C (-77F) to 85°C (185F)
Up to 30MB/s Write Speed
Has SDXC1 with "3" inside of U-Bracket
WD Purple MicroSD card specifications
Q: How long will it store the footage?
A: Using H.264, 64 GB is about 24 hours of continuous footage for one camera that records at 1080P 30 FPS.
A: Using H.265, 32 GB is about 24 hours of continuous footage for one camera that records at 1080P 30 FPS.

These are statements I copied/pasted from various websites discussing the particulars of MicroSD cards. The top dog in all reviews was the Samsung PRO Endurance. Followed by 3 or 4 lesser cards. No mention of Western Digital Purple MicroSD cards anywhere for IP camera duty, which I found strange.
Some statements seemed....conflicting. A SDXC1 with "1" in the U-Bracket should mean 10MB/second write speed. Which is what is viewable on the Samsung PRO Endurance card itself, yet it claims 30MB/second write speed. The WD card does have "3" in its bracket.
Another is the temperature. PRO endurance says -40F to 185F but then in the fine print it says that temp is for non-operating temp. Western Digital card can go down to -77F...but does not say operating or non-operating temp.
And finally, some bells & whistles I am not familiar with. Western Digital card has the Card Health Monitoring when paired with specific cameras (must mean photography cameras not IP cameras) and uses 96 layer 3D NAND tech. Could not find the layer tech for the Endurance.
Price via Amazon: 128GB Samsung PRO Endurance = $26. For the Western Digital Purple Q101 128GB: $39
I personally bought all WD Purple cards for my cameras, only because of the highly recommended WD Purple for Blue Iris HD use. If any fail or I may need to purchase more cards, I'll give the Samsung PRO Endurance a shot.

There are some serious science and engineering specifications well above what my head can handle. I'll be sticking to either the PRO or WD
