(1) sending a portion of the information corresponding to the types of sensors of the second detection device;

or

(2) sending a portion of the information capable of being processed with the processing power of the second detection device.

7. The method of claim 1, wherein the information comprises at least one of:

(1) sensor data outputted by at least one sensor of the first detection device;

(2) identity data indicating a determined identity based on the sensor data;

(3) characteristic data of the UAV, wherein the characteristic data comprises at least one of speed, direction, range, or altitude of the UAV;

or

(4) secondary data, wherein the secondary data comprises a timestamp at which the sensor data, identity data, or characteristic data is determined.

8. A method for managing detection and identification of an Unmanned Aerial Vehicle (UAV) by a second detection device, which is configured to detect the UAV in a second detection area, based on information sent by a first detection device, which is configured to detect the UAV in a first detection area, the method comprising:

receiving, by the second detection device, the information related to the UAV from the first detection device; and

determining, by the second detection device, an identity of the UAV based, at least in part, on the information.

9. The method of claim 8, further comprising:

receiving an Estimated Time of Arrival (ETA) of the UAV for reaching the second detection area of the second detection device;

determining whether any UAV has been detected at the ETA; and

determining whether a detected UAV and the UAV corresponding to the ETA are the same.

10. The method of claim 8, wherein determining the identity of the UAV is based, at least in part, on the information and a trust factor corresponding to the information.

11. The method of claim 10, wherein the trust factor is based on one or more of:

(1) a predetermined value;

(2) a measurement time interval starting when the UAV enters the first detection area of the first detection device and ending when the UAV exits the first detection area of the first detection device;

(3) a distance that the UAV traveled within the first detection area of the first detection device;

(4) types of sensors used by the first detection device to determine the information;

(5) accuracy of at least one of the sensors used by the first detection device to determine the information;

(6) a hysteretic value reflecting historic accuracies of the information outputted by the first detection device previously;

(7) a time duration since data outputted by at least one of the sensors has been obtained; and

(8) environmental conditions within the first detection area of the first detection device.

12. The method of claim 10, further comprising determining whether the information needs to be updated based on the trust factor by determining whether the trust factor crosses a threshold.

13. A method for managing detection and identification of an Unmanned Aerial Vehicle (UAV) by a central server connected to a first detection device and a plurality of detection devices, the method comprising:
