Ensure Long Time Run： Ensure long-term stable operation of the equipment

The stable operation of the device requires not only the use of low-power components, but also the stability during the sleep wake work sleep process of each component. For example, the scheduling program of the main control chip not only needs to complete image acquisition, compression, AI recognition and other tasks within the maximum time, but also needs to coordinate with other units. This not only involves IPC architecture design, but also requires deep technical support. Therefore, the AOV mode requires stability for each component.

The management and detection technology of battery power is also a key factor affecting the long-term stable operation of equipment. For example, when the battery level is too low, how to ensure the maximum operation of the device and wait for the battery level to recover before resuming work.

 

Ensure  No Omission： Ensure that the event is restored without any omissions

To ensure accurate event restoration, it is necessary to achieve 7 * 24-hour recording. Ordinary low-power cameras use PIR triggered alarm recording, and do not record when not triggered. AOV mode change means working at full frame rate when there are people present and reducing frame rate when there are no people present.

The commonly used frame rate reduction here is 1 second per frame, as well as 2 seconds per frame or even 10 seconds per frame. The impact of the time interval on AOV is that if there is a human shadow during the interval period, and the movement speed of the human shadow is very fast, setting a long time interval will result in false negatives. For example, every 10 seconds, if someone enters the first frame and leaves the monitoring range within 5 seconds, a false alarm will occur.

Therefore, the most suitable range for reducing frame rate in AOV mode is 1 second per frame.

In addition, black light full-color technology is also a technical guarantee for improving the quality of AOV recording. We won‘t delve into the black light full-color technology here.

 

Ensure  THE Completeness： Ensure the integrity of the event

To ensure the integrity of the event, the triggering of the alarm must be accurate and fast, which involves the recognition technology of human or vehicle shapes. Another is the fast writing technology and pre recording technology of the TF card for storing video files. The third is the push of alarm messages, which involves the stable control technology of the 4G module, so as to form a complete event time chain.

 

Ensure Smooth Video： Ensure the smoothness of video recording

To ensure the smoothness of video playback, it involves fast memory wake-up technology, video file transfer technology during 4G viewing, and encoding technology when switching from low frame rate to full frame rate

AOV cameras have the characteristics of long battery life, long alarm distance, and excellent image quality. They are also easy to install after purchase, making them very suitable for use in environments without power or grid, such as villas, farms, temporary construction sites, orchards, fish ponds, and other places in the suburbs.
