Remote control electronic anti-theft lock At present, the common remote-controlled electronic anti-theft locks mainly include optical remote control and radio remote control. The optical remote control is further divided into an infrared remote control and a visible light remote control. The optical remote control utilizes a narrow angle optical transmission password, and the advantage is that the amount of information transmitted can be large, the speed is extremely fast, the human eye can not recognize it, and cannot be in the light path (operator and The electronic anti-theft lock between the main body) attempts to copy with the instrument capture signal, so the confidentiality is extremely high. Radio remote control is also the advantage of transmitted information can be large, fast, human eye can not, but the signal transmitted spatial dispersion, the instrument is easily captured, and therefore suitable for "change password", such as the so-called "code hopping" "Rolling code" (both are random changes without obvious laws), so that even if the signal at the time is captured, there is no value of utilization and copying. The use of a remote-controlled electronic anti-theft lock requires careful storage of the remote control (ie, the key), and for some applications, the key is a bit larger and may require the use of a specific battery. Keyboard type electronic code lock From the current technical level and market recognition level, the most widely used is the keyboard type electronic code lock, which is mainly used in safes, safes and vaults, and some are used in safe deposit boxes and cash transport vehicles. The keyboard type electronic password is input on the keyboard, which is similar to the telephone call, so it is easy to grasp. The outstanding advantage is that the "password" is the number and character recorded in the mind of the authorized person, which is accurate and reliable, and will not be lost (except forgot). It is difficult to be stolen (unless you disclose it yourself). But the password can't be too simple. It's too easy to be tested by others on the keyboard, or it may be sneaked by bystanders, resulting in insufficient confidentiality. Of course, the password can not be too complicated, too complicated, may be confused, or the input password operation success rate is low, resulting in inconvenient use. Therefore, in order to carry forward the advantages and overcome the weaknesses, keyboard-type electronic passwords are also constantly developing.
