With the development of smart homes , more and more smart products have entered people's lives, especially smart cameras that can be remotely monitored and intelligently burglar-proof. For home users, to create a safer and better life for people, step into the smart Home, the purchase of smart cameras is very important.
There are a few issues to be aware of when purchasing a smart camera:
1. The size of the lens determines the breadth of the camera angle
The most direct factor affecting the size of the smart camera's view is the lens size. The appearance of the lens of the smart camera looks similar, but the size is not the same. The common size is 2.8mm/3.6mm/4mm/6mm/8mm/12mm. For most smart cameras, the larger the lens size, the farther the picture can be, but the narrower the viewing angle. This is all about fixed cameras.
Analysis: If consumers want a smart camera to see a wider angle, it is recommended to buy a smart camera with a pan/tilt. The rotation mode of the gimbal can also be divided into three types: 1. It is necessary to control the rotation angle of the camera through the mobile phone; 2. Automatic rotation; 3. Set the positioning. Most of the pan/tilt rotations on the market need to be controlled by mobile phones, and the smoothness and positioning of the rotation is very important.
2. Resolution determines picture clarity
Needless to say, the resolution determines the sharpness of the picture. The higher the resolution, the higher the resolution of the camera. This is like, your nearsightedness of 500 degrees, not wearing a pair of 250 degrees of glasses, it obviously does not work, walking on the road Zhang San Li four silly and unclear, if you put on a pair of 500 degrees of glasses vision is bright. Currently, the resolution of smart cameras on the market can be divided into the following three types: 480P, 720P and 1080P.
Analysis: Although the 480P resolution smart camera is cheap, but the resolution is low, it looks very vague, belonging to the low-end products in the smart camera, advise buyers not to consider. The 720P resolution is the smart camera of 1080P resolution adopted by most manufacturers at present. In the current view, the smart camera with 1080P is considered as a high-end product.
3. Video storage mode
Video storage methods are divided into local storage and cloud storage. Both have advantages and disadvantages. Cloud storage is more secure than local storage, and even if the criminals take the camera away, you can still view it in real time through the mobile phone. When a smart camera with local storage is lost, the memory card inserted in the body is lost, cannot be retrieved, and there is a danger of revealing privacy.
In cloud storage mode, the device will send the video to the remote server; local storage requires a separate accessory (SD card, DVR) to store the video you want, and what storage method to choose depends mainly on customer needs.
Analysis: Everything is a double-edged sword, and because local storage stores video on a memory card, it can store clearer and larger videos. While cloud storage relies on network transmission, video quality is limited by the strength of the network signal. If the signal is not good, the transmission will be interrupted.
Faced with a variety of smart camera brands on the market, consumers are often dazzled and do not know how to choose. Here are a few good home smart cameras for 2016:
1.360 smart camera 1080P
Uses: live broadcast, housekeeping shop
