Durable, intelligent keyless entry locks on the rise

says globalsources.com

Enhancements geared to provide better protection against unauthorised entry.

To reduce models' susceptibility to lock picking, makers are designing constructions with fewer junctures. Companies are releasing more one-piece units, which are made via die casting. Such products generally target the high end since they are 10 to 20 percent more costly to manufacture.

As regards access modes, most keyless locks have at least two. For card-operated and fi ngerprint-recognition systems, the major categories in the line, a password often has to be entered as well before entry is gained.

Zhongshan Tieshen Lock is employing a face recognition technology, which was developed in-house. Developed for residential applications, its MR55 model targets the high-end markets of Japan, South Korea, the US and Europe. The product is designed to work with other keyless entry systems.

For better anti-theft protection, a number of card lock suppliers have introduced devices that emit an alarm when an unauthorized card is used. At Qingdao Dannuo the selection includes units that relock automatically if the door is not opened within 10 seconds.

Yongkang Egate Electronics Technology offers a digital lock cylinder that can replace standard mechanical types directly. Used in conjunction with card systems, the product allows controllers to schedule access to an area. It records entry and exit data, which can be retrieved by a handheld terminal.

Other manufacturers are pursuing higher accuracy rates to minimise false acceptance and rejection. Yuhuan Wasble Machinery Co's WSB631 and WSB661 models boast specifications of over 98 percent accuracy.

Aiming for greater user convenience, several companies have released keyless locks that can be opened via a remote control or a mobile phone. Shenzhen Jieli Products is among the enterprises that have taken this route.

More designs are also being installed with a low-voltage warning function to indicate when batteries need to be changed. Some units can be accessed 100 more times after the alarm, giving users a chance to make the replacement.
