Look at these points when buying an infrared detector! Did you buy it right?
Why the security equipment that all families must install is the "infrared detector", to say performance! There are not many security products with higher detection sensitivity and lower false alarm rate than it, but the more advanced things are less suitable for the public, because its price is not very "public", and the infrared detector is such a "good quality" and "price" "Inexpensive" security products, so it will become a must for every household.
In terms of product selectivity and applicability, the infrared detector has also been changed in external appearance according to the different places of use of the product, making it more suitable for the installation environment.
For example, in the living room, where the detection area is large and the range is wide, we use the "infrared wide-angle detector", which is also relatively sturdy in shape, with sharp edges and corners, and the hidden components in the wide "chest cavity" are ultra-wide-angle detection. 110° wide-angle detection is possible, and the detection distance can be up to 12m. It is completely enough in a large space such as a living room. If you want to use it in a wider place such as a warehouse, you can install a few more, and cooperate with the "ceiling infrared detector", the effect will be better!
"Infrared Ceiling Detector", as the name implies, is an infrared detector installed on the ceiling. Because of the different installation methods, the detection method is also very different. It is a top-down spiral detection range, 360° detection, detection height Up to 12m, the detection radius is 6m. Infrared detectors of this type are mostly used in bedrooms, study rooms and other places where the detection area is small and relatively concentrated.
Finally, there is a type of infrared detector-"infrared curtain detector", but its detection area is a bit strange, not a space, but similar to a wall, a wall monitored by infrared detection, as long as someone passes through this wall , The alarm will be triggered. The maximum detection distance of this type of detector is 8m, and the detection angle is only 15°. This type of detector is mainly aimed at the entrance and exit areas such as doorways, glass, balconies, etc., to prevent people from entering.

General infrared detectors are divided into these three categories. Of course, we can also add a microwave detection function on the basis of infrared detection, thereby becoming a dual-detector detector and increasing the accuracy of the detection results.
Aluminum shears cut scrap metal and help to separate different material types, earning you more money from your metals. Our shears are ideal for recycling scrap bar, tube, extrusions, car radiators, gear boxes and gate valves. We have been manufacturing alligator shears for more than 30 years. Ecohydraulic shears come in all sizes and are typically described according to blade length in mm. They can be powered by both single and 3 phase power supplies. Some shears have a diesel option. Operator safety is upper-most in mind so our range of shears are equipped with blade guards and foot-operated switches.
