That's how the IP camera is selected
IP surveillance camera selection, different IP surveillance camera manufacturers have different suggestions, different ways of purchasing.Xiaobian think that the purchase of IP surveillance camera, as long as users pay attention to these points can be.
I. Storage mode of IP surveillance camera
Once there is a problem with the storage of the monitoring system, the whole system will lose the basic function of restoring the truth of the video.There are three types of monitoring storage: VCR hard disk storage;SD card storage;Cloud storage.There is no need to set the plug-in card storage camera. It can support recording by inserting cartoon power. The mode is cyclic recording, and the earlier recording will be overwritten when the memory card is full.Cloud storage is the product of the development of Internet technology. Many household monitoring brands support cloud video recording, cloud access and playback.
Ii. Focal length of IP surveillance camera
IP surveillance cameras normally use 2.8 mm, 4 mm, 6 mm, 8 mm, 12 mm lens focal lengths.The lens of the surveillance camera can be selected according to the monitored object. Generally, the smaller the focal length of the lens, the larger the Angle range seen, but the shorter the monitored distance.So the 2.8mm lens is suitable for points in narrow environments such as stairways and elevators, 4mm for rooms, 6mm for corridors or door units, 8mm for workshops or corridors, and 12mm for narrow roads.
Iii. IP surveillance camera resolution
The resolution of IP monitoring camera is the definition we usually say. The higher the resolution, the higher the pixel, the clearer the image. Now the network camera usually uses more than 1 million, 2 million and 4 million pixels, which can basically meet the requirements of normal monitoring and use.The higher the resolution, the larger the storage space of the surveillance video will be, and then the storage time will be shorter. Therefore, when we consider the clarity, we should also consider the storage time of the video recording.
Iv. IP surveillance camera movement detection
No matter you are equipped with an INDOOR or outdoor IP surveillance camera, the motion detection function can well add a safeguard to security surveillance. When there is an unusual intrusion, the IP surveillance camera can send out an alarm at the first time and inform users to deal with it through SMS or email.
