At present, home security cameras mainly use two kinds of data storage mechanisms. One is to store surveillance videos in local storage, and the other is cloud space. So, which one is the best choice? May depend on your needs, let's take a look.
<br> <br> local store security cameras are a lot of mainstream support local storage, you were basically chose micro SD card, such as Samsung Smart Cam HD, D-Link DCS -2630 L and so on, up to 128GB capacity expansion. In mobile applications, users can set up their storage mechanisms, such as recording 24 hours a day or not until recording is detected. If you select 24 hours of uninterrupted recording, the user needs to choose to overwrite the previous content or stop recording when the memory card is full.
The advantage of local storage is that you don't have to worry about vulnerabilities in the vendor's cloud storage, causing privacy video leaks, and you don't have to pay monthly service fees.
Cloud storage
Security cameras such as the Nest Cam, Kodak CFH-V20, and Netgear Arlo Q use cloud storage. This means that users need to pay a certain service fee. The general price is about 10 US dollars per month (about 65 yuan). Cloud storage can be more easily applied in non-stop monitoring mode, without worrying about insufficient storage of SD card, or some key content is covered. Of course, cloud storage is a certain risk. After all, current hackers are omnipotent, and Internet user data leakage is also commonplace.
Oil Seal is a mechanical components that used to seal oil (oil is the most common transmission system liquid material), It`s isolated the lubricated components with other components, not let the lubricate oil leakage.
Oil Seal is generally divided into single-type and assembly type, assembly type is the skeleton and lip material can be free combination, generally used for special oil seals.
Oil seal can have different names, customary general rotary axis lip seal called oil seal, the static seal and dynamic seal (general reciprocating motion) was called seal parts.
The representative form of oil seal is TC type, is a double lips oil seal with a fully rubber coated and garter spring, generally speaking oil seal refers to TC skeleton oil seal, skeleton oil seal diagram see Figure:
Generally when the oil seal is working ,its lips area temperature is higher 20-50℃ than working medium. Make sure you noted this when you select the oil seal products.
Oil seal operating range is related to its material:
NBR: -40 to 120℃,
ACM: -30~180℃
FPM: -25~300℃
Application:
Any operate case which have liquid lubricants inside and need to connect with outside also, the connect place is required of oil seals.
Engine: crankshaft - crankshaft front and rear oil seal, valve - valve oil seal (engine repair kit o-ring) (distributor oil seal, pump oil seal, balance shaft oil seal, oil pump seal ...);
Camshaft - camshaft oil seal ; Transmission: transmission front oil seal, transmission rear oil seal, transmission shift oil seal (transmission repair kits o-ring)
Sub actuator front oil seal, Sub actuator rear oil seal,
rear axle: axle oil seal
