Teach you how to calculate the power of an intelligent infrared camera

As the name implies, the intelligent infrared camera is a smart camera designed by the principle of infrared thermal imaging. The application of infrared thermal imaging technology can make the surveillance camera not interfere with low illumination and strong sunlight, and can automatically eliminate shadows and bad weather. Impact, this is an advantage that traditional surveillance cameras can't match.
Since its introduction, the intelligent infrared camera has gained wide application due to its outstanding advantages such as long night vision distance, strong concealment and stable performance. In practical applications, it has to consider the power supply problem. The following is a small series for everyone to introduce the calculation method of infrared camera power.
Due to the instant of the infrared camera, the starting current is very large, coupled with the loss of long-distance transmission in engineering. Therefore, the power required for surveillance cameras is not simply the sum of the power ratings of all cameras. The correct way to calculate the power of the infrared camera is to add the power of the camera of the entire monitoring system and multiply it by 1.3 times. This is the actual power required by the camera, and then add about 30 losses; finally add 30 Quantity, used as future expansion.

Infrared camera power calculation method:
If there is 100 in a business building and the rated power of each surveillance camera is 4W, how do we configure the camera power supply?
According to the above calculation method, we calculated that the rated power of the camera is 4W*100 units 400W.
The actual power used by the camera is 400W*1.3520W.
After considering the loss, the power required by the camera is 520W*1.3676W.
With the power supply margin, the power supply that the camera finally needs to be configured is 676W*1.3878W.
Summarized as follows: the power supply camera needs to be configured with the power rating of the camera *1.3*1.3*1.3
(Note: If the monitoring distance is extremely long, it is necessary to increase the power supply appropriately and increase the power supply voltage)
In addition, when calculating the power of the infrared camera, if you have a motorized zoom lens, you need to add about 800mA of current required by the motorized lens to get the working current required by the entire infrared zoom camera. It is worth noting that the infrared lamps of infrared cameras are also imported and domestically produced, and the actual required electric power is also different. Some manufacturers increase the power of the infrared lamp, and the actual consumption is still greater than the nominal current.
Nowadays, intelligent infrared cameras are basically not produced abroad, because infrared cameras are very dangerous in most monitoring environments. In addition, their low price competition seriously affects product life. The short product life is perhaps for infrared camera manufacturers. More profit margins, the infrared camera market is unstoppable, so all intelligent infrared camera manufacturers are constantly developing more cost-effective products.
