In today’s high-technology world, small doesn’t necessarily mean less powerful anymore. In fact, the most sought-after gadgets and gizmos are often those which are the most compact. A small size definitely presents a lot of advantages as well as many different opportunities.

In the realm of security, size also has it uses. Often, the smallest security devices are also the most inconspicuous, giving it the advantage of stealth. Because today’s thieves and criminals are well-versed when it comes to security systems, security devices that can be spotted at once can simply be disabled or tricked. Tiny, inconspicuous and invisible devices eliminate that risk. When intruders and thieves are sneaking up on your premises to take you by the surprise, small and invisible security devices can take them by surprise as well.

Do not risk the safety of your family, your belongings or yourself. For all those reasons, we’d like to introduce to you one of the smallest motion detectors available today: the Visonic SPY4 Infared Motion Detector.

Visonic SPY4 Infared Motion Detector

The Visonic SPY4 Infared Motion Detector is a miniature cylinder-shaped motion detector. This product is made by Visonic, a name with more than three decades of experience in the realm of home and office security. It is a brand that is respected among its peers in the industry.

Measuring 0.75” in diameter and 2.75” in length, the Visonic SPY4 Infared Motion Detector is the smallest infared motion detector for its power and versatility. Because you only need to expose its lens when you mount it, it becomes almost invisible to the naked eye after installation. However, don’t let the size fool you; the Visonic SPY4 Infared Motion Detector has a lot more to brag than just its size.

The Visonic SPY4 Infared Motion Detector is specially designed to guard corridors, doors and windows. It is suitable for both wall and ceiling installations, either by mounting it with a press-fit collar or a mounting plate (both included with the package). Even with its small size, it has a range of about 2m (in width) and about 4m (in height). It is very rugged and reliable, and is able to distinguish between malicious intrusion and false alarms. You will definitely not be hassled because this motion detector does not “cry wolf”.

One very good feature of the Visonic SPY4 Infared Motion Detector is its ability to detect curtain patterns. Because of this, your innocent curtains cannot be mistaken for intruders, and even the most experienced thieves will find that hiding behind the curtain does them no good. Because of this, it is suitable for guarding windows with curtains—a potential weak spot of your home or office.

Of course, this infared motion detector has a variety of other uses. You may use it for access systems, CCTV controls and such systems which require a highly reliable motion detection system. It is great for home or commercial uses, and it is definitely worth considering when you’re looking to install a security system. Small is powerful!
