The infrared sensor camera purchase platform believes that it should be selected from the following aspects:
Lens: Infrared sensor-triggered cameras generally use CMOS lenses, and now the physical pixels can reach 4000x3000. The difference is that the wide-angle lens of the general infrared sensor-triggered camera is 52°, and the camera of the wide-angle series can reach 100°. The larger the wide-angle lens, the larger the shooting range.
Infrared sensor: Infrared sensor is the infrared-sensing sensing distance, that is, the target can be triggered by the infrared sensor camera within the distance range, generally 15-20 meters.
Storage space: This type of camera generally does not have its own storage space. It needs to be stored by SD card. It can support up to 32G, but some models can only support 16G. Please pay attention when purchasing this.
TFT display position: The display is easier to determine the target when installing on the back of the camera lens. Some products have a laser to establish the target position, which is very user-friendly.
Trigger start time: It is the camera start-up time from the discovery of the target to the photo or video recording. It is generally between 0.6s and 1.5s. Do not underestimate the fraction of a second. It can determine whether the camera can capture the moving target.
Standby time: mainly depends on the number of batteries, some products can hold 4-12 batteries, and some can only hold 8 batteries, but also determine the standby time according to the quality of the battery, the general theoretical standby time is 3-6 month.
Working temperature and humidity: Generally, the camera can work in the range of temperature -25 ° ~ +70 ° C and humidity 5% ~ 95%, and the lowest temperature of the product can reach -35 °, suitable for use in cold regions.
Product quality and system stability: These products are generally used in the field, the quality and stability of the products must be good, otherwise it will waste time.
After-sales service: These products are generally guaranteed for one year.
The optional infrared sensor trigger camera generally starts from the above aspects, the software is convenient as long as the setting is convenient, the design is humanized, and the difference is generally small. In addition, the purchase of products depends on the environment in which they are used and the length of use, as well as the size of the camera and the range of activities.
