One of the best ways to deter vandals, miscreants, burglars etc from entering your residential premises, is to set up an efficient camera system. Of course many people also use their CCTV cameras for indoor surveillance in their home; to monitor their baby or even to keep an eye on domestic help. Regardless of the brand, if you are setting up a new security system, there is some basic planning you should be doing.

Some wireless CCTV cameras are basic plug and play ones, and you won’t have trouble setting them up yourself. However, if you have chosen the more complex and advanced systems, you would need a professional to handle the installation and set-up for you.

The company you choose for the job should be able to handle all the cabling and hardware installation. For advice or CCTV system installation services, call Allround Electrical at 1300 169 263. You can also drop us a line via email.

When it comes to crime, it’s evident that there’s an appeal to darkness. Less visibility means less chance of getting caught. The 2014 National Incident-Based Reporting System (NIBRS)—an annual Uniform Crime Reporting (UCR) Program publication that’s released by the FBI—includes detailed crime data, such as time of day and type of offense. More than 18,000 law enforcement agencies participate in the UCR Program and provide data voluntarily. NIBRS’ Crimes Against Persons data shows that of the 1,093,466 incidents reported in 2014, 562,104 (51.4 percent) were between the hours of 6 p.m. and 6 a.m. Crimes Against Property data shows a lower—yet significant—39.4 percent of 3,493,904 reported incidents taking place between those same hours.

In an attempt to lessen crime and increase energy savings, many cities and businesses have started replacing traditional high-intensity discharge (HID) lights with LED bulbs, light engines, and fixtures. These actions have paid off. In 2008, Los Angeles began a project to retrofit 215,000 lights with LED lights. Since implementation of the project, color-rendering indexes (CRI) than HID fixtures. CRI refers to how accurately a light source reveals the true colors of objects, people, and surroundings. The CRI of an HID bulb can range from zero (high-pressure sodium) to about 65 (metal-halide). LED fixtures are capable of having CRIs of 75 and higher. Lights with a CRI of 80 or higher are considered to show colors most accurately and increase visibility, which is especially important for security purposes and parking lot surveillance.

Insect Vision: Ultraviolet, Color, and LED Light, Marianne Shockley Cruz and Rebecca Lindner from the University of Georgia’s Department of Entomology write, “Experimental work supports the idea that color perception exists in insects and that they are especially responsive to the shorter wavelengths of the visible spectrum and UV light.” Wavelengths are measured in nanometers, and shorter wavelengths of light (less than 550 nanometers) can indicate ultraviolet (UV), blue, or green colors. Cruz and Lindner also cite work that confirms the correlation between UV light from the sun and moon and how certain bugs navigate Earth. Another point to remember about bugs is that certain types, such as mosquitoes, are attracted to heat and have thermal receptors to help them find it. All of this information is helpful for determining why bugs flock to certain light sources.

The color that is emitted from a light source is important because of its ability to attract bugs. As previously stated, shorter wavelengths (UV, blue, and green light) are more visible to bugs than longer wavelengths (yellow, orange, and red light) and, therefore, will draw them closer. Incandescent, compact fluorescent (CFL), halogen, and high-intensity discharge (HID) lights emit UV radiation that is attractive to bugs, and since certain types of bugs navigate by UV light from the sun and moon, a closer, brighter source of UV light can disrupt their orientation and draw them in. LEDs produce very little to no UV light, which makes them less visible to bugs. However, it is still possible for an LED bulb to produce shorter wavelengths of light (bluish-white/cool white color), which will be more attractive to bugs. Therefore, when browsing for LED lights that will attract less bugs, it’s important to choose a fixture that emits more wavelengths that are above 550 nanometers, such as warm white, ultra warm white, or yellow lights.

CCT) instead of nanometers, it’s easy to tell if the bulb will be more or less visible to bugs. CCT is measured in Kelvin (K), and different temperatures on the Kelvin scale represent different colors. An LED bulb with a CCT below 3600K will emit warm or ultra warm white light that’s not easily seen by bugs. Bulbs with CCTs of 3600K and above will emit natural or cool white light that is more likely to attract bugs.

Incandescent, halogen, CFL, and HID bulbs waste most of the energy they consume—as much as 90 percent—in the form of heat. Bugs with thermal receptors can sense the heat released by these light sources. LED bulbs produce a minuscule amount of heat, which makes them less appealing to bugs.

Bug lights are simply light bulbs with a yellow coating that decreases the color temperature of emitted light. Because of the coating, bulbs will emit a peak wavelength of light that is around 550-600 nanometers. However, you don’t need a yellow-coated bulb to reduce the presence of bugs. LED lights that emit warm-colored illumination, such as yellow malibu light bulbs for landscape applications, or From top left to bottom right: incandescent bug light, yellow LED strip lights, yellow LED malibu light bulb installed in landscape fixture, and gold-tint LED filament bulbs

Ecologist Michael Justice performed an experiment to determine the type of residential light that attracts the least amount of bugs. He used six lighting types inside of an insect trap each night during the summer. Justice also made efforts to equalize the effects of weather and the moon’s irradiance. His LED Z-Bug Bulb™ from NEBO is a bug zapper and an LED bulb in one. The bulb emits white illumination from its top and ultraviolet (UV) light from its caged center. The UV light attracts mosquitoes and other insects toward the bulb’s high-voltage electric grid and kills them on contact.

Because different types of bugs see different wavelengths, it is never guaranteed that an LED light won’t attract them. However, most bugs are attracted to short wavelengths of light and are especially drawn to UV light; they can see it better, and some use it for navigation. Bulbs that emit more short wavelengths of light (cool white/bluish color) will attract more bugs. Lights that emit a majority of longer wavelengths (yellow/orange/red colors) are less visible. Heat can also draw bugs into an area. LED lights produce little to no UV light and a minuscule amount heat, which makes them less attractive to bugs—so long as they emit longer wavelengths of light.
