Abstract
The invention provides an anti-interference security monitoring device, which comprises a base body and a monitoring lens, wherein the base body is provided with a first lens and a second lens; the antenna structure is led out of the substrate; the antenna structure comprises a cable which extends along the wall body and is more than one meter; the cable comprises more than 5 shielding wires which are arranged in parallel, each shielding wire is provided with an exposed section, and the exposed section is not coated with a shielding layer, so that the conductive inner core in the exposed section can transmit electromagnetic waves outwards; the exposed sections on the shielding wires are staggered with each other, and the projection of each exposed section on the cable covers the whole cable; the shield wires are commonly coupled to a transmission module in the antenna structure. This anti-interference security protection monitoring device can avoid antenna structure to be shielded to a great extent, has higher interference immunity.
Description
Technical Field
The invention relates to the field of security equipment, in particular to a security monitoring device.
Background
At present, more security monitoring equipment adopts a wireless transmission mode to transmit monitoring videos; for the wireless transmission monitoring equipment, lawbreakers can destroy the wireless transmission monitoring equipment in an electromagnetic interference mode; for example, by arranging a permanent magnet at any position of the antenna part of the monitoring device, the whole antenna can be seriously interfered, and data cannot be normally transmitted.
Disclosure of Invention
In view of the above problems, an object of the present invention is to provide an anti-interference security monitoring apparatus, which can prevent the antenna structure from being shielded to a greater extent and has higher anti-interference performance.
The technical scheme adopted by the invention for solving the technical problems is as follows: the anti-interference security monitoring device comprises a base body and a monitoring lens; the antenna structure is led out of the substrate; the antenna structure comprises a cable which extends along the wall body and is more than one meter; the cable comprises more than 5 shielding wires which are arranged in parallel, each shielding wire is provided with an exposed section, and the exposed section is not coated with a shielding layer, so that the conductive inner core in the exposed section can transmit electromagnetic waves outwards; the exposed sections on the shielding wires are staggered with each other, and the projection of each exposed section on the cable covers the whole cable; the shield wires are commonly coupled to a transmission module in the antenna structure.
Preferably, the free end of the cable is covered by a metal cover, and the metal cover does not contact with the conductive inner core in the cable to shield the end of the cable, so that the electromagnetic energy in the cable can only flow out of the exposed section of each shielding wire.
The invention has the beneficial effects that: when the anti-interference security monitoring device is used, if a metal cover or a permanent magnet is adopted to interfere an antenna structure mainly formed by a cable, the anti-interference security monitoring device can only interfere one section of shielding wire in the cable due to the limitation of size (the interference device can only be close to an exposed section of one section of shielding wire generally), and other shielding wires are not influenced at all, so that video signals can be transmitted to the outside through the exposed sections of other shielding wires; thereby achieving a high interference immunity.

Fig. 2 is a schematic diagram of an embodiment of a cable in the anti-interference security monitoring device.
Detailed Description
The invention is further illustrated with reference to the following figures and examples:
in the embodiment shown in fig. 1 and 2, the anti-interference security monitoring device includes a base 1 and a monitoring lens 2; the antenna structure is led out of the substrate; the antenna structure comprises a cable 3 extending along the wall for more than one meter; as shown in fig. 2, the cable 3 includes 5 shielding wires 31 arranged in parallel, each shielding wire 31 includes a conductive inner core and a shielding layer, each shielding wire 31 has a segment of exposed segment 310, and the exposed segment 310 is not covered with the shielding layer, so that the conductive inner core in the exposed segment 310 can transmit electromagnetic waves outwards; the exposed sections 310 on the shielding wires 31 are staggered, and the projection of each exposed section 310 on the cable 3 covers the whole cable 3; the shield lines 31 are commonly coupled to a transmission module (base module, not shown) in the antenna structure.
In the security monitoring device, the free end of the cable 3 is covered by the metal cover, and the metal cover is not in contact with the conductive inner core in the cable 3, so as to shield the end of the cable, so that the electromagnetic energy in the cable 3 can only flow out from the exposed section 310 of each shielded wire.
When the anti-interference security monitoring device is used, if a metal cover or a permanent magnet is adopted to interfere with an antenna structure mainly composed of cables 3, due to the limitation of size (the length of the cable 3 is more than one meter, and the interference device is difficult to reach the size), interference can be only formed on one section of shielding wire 31 in the cable (the interference device can only be close to the exposed section of one section of shielding wire generally), other shielding wires are not influenced at all, and video signals can be transmitted to the outside through the exposed sections of other shielding wires; thereby achieving a high interference immunity.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, but rather as the subject matter of the invention is intended to cover all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.
