Security lights get switched on whenever it detects an intruder within its field of view. Such systems may be based on PIR or Photosensitive sensors. A PIR may be connected to normal lights to make security lights (requires technical knowledge). Security lights are very useful to scare the intruders especially if these lights are employed in the compound or on the roof tops. When the lights are switched ON, the intruder feels that he has been detected and the owner is trying to confirm this. Normally this will deter the intruder for making any further attempt.
For safety and security of homes and offices specially when there is no one in the house automatic/timer based lights are very helpful. Such lights are automatically switched on after a predefined time. Normally, it is feasible to program these lights to switch ON or OFF at any particular time. However, if the house is going to be alone for a long time then a thief can see that the lights are switched on or off at the time same time every day (provided he is keeping a vigil over days). This may arise his suspicion and such a light may not be useful in such situations.
Dont worry about lighting, PIR sensors can automatically switch lights on and can greatly enhance both safety and comfort to a home. PIR lights and automatic light switches form an integral part of safety and security around your home. They offer support for family members who tend to rise from bed at night and illuminate windowless areas eg. cellar, shed or garage. Also, a PIR light does not need to be turned off, it emits a soft, warm light only until you have returned to bed or left the room.
A PIR light is usually simple to install, particularly the night lights which just plug straight into a wall socket. PIR lighting is the perfect way to ensure safe movement around the home at all times of day. PIR lighting uses passive infrared motion sensors to detect heat and movement within a given range. These sensors trigger the activation of a built in light.
PIR lights can also help with safety outside properties to reduce falls at night or be useful for guests coming to your property in the dark. Most PIR lights are fitted with an adjustable timer which extinguishes the light after the preferred length of time.
Automatic light switches offer another kind of home safety, they provide guaranteed illumination in an area for a set time, or, if installed with an automatic light sensor, it means the light will switch on once natural daylight fades. Relatives and carers know that certain areas will be well lit until the person they care for retires to bed. By fitting a table lamp in your living room with an automatic light switch, you create the illusion that you are still at home, even when you are not. Automatic lights are ideal for those who often work away from home or travel frequently to a second property, reducing reliance on family or neighbours to manage your empty house.
There is a wide range of PIR lights and automatic lighting available from RK & Sons.

Image projectors have been used as modern tools in many sectors of the society. The two main sectors that benefit greatly from projector technology are the commercial sector and the entertainment sector.
Generally speaking, projector technology is very important because of many things including movie projectors used in movie theatres. Most people enjoy watching movies and perhaps without projector technology, it would not be a similar experience. Slide projectors are also beneficial to the community as it is used in academic institutions to provide a dynamic way of learning for students. It is also used in business functions where images are used for data and analyses. Overall, projector technology has contributed to every societys growth and development, which makes this piece of modern technology very beneficial.
Largest possible picture. Front projectors generate the biggest possible image size. You can use them to create the very large screen experience of a commercial movie theater in your own home. In theory, actual image size can go up to 300" diagonal or more. But in reality the size of any given projector's image is limited by its light output. Nevertheless, most projectors produce beautiful images at sizes of 90" to 120" diagonal, which is far larger than anything you can get with flatscreen TVs or rear-projection TVs.
Smaller images a great option also. Perhaps you don't want a huge image, or maybe you don't have space for one. If this is the case, a projector can be used to throw a smaller image, say about 60" diagonal. So it can serve as an inexpensive substitute for a 60" plasma TV. At this image size the picture is usually very bright, and can be used with some of the room lights on. Given the low cost of many entry level projectors, this can be the least expensive way to get a 60" picture on your wall.
RK's exciting line-up of LCD & DLP multimedia projectors deliver the right display solution for the classroom, boardroom, lecture hall or any collaborative meeting space.

Most uninterruptible power supplies contain a surge protector to protect your electronics should an electrical surge happen such as a lighting strike from a thunder storm. An uninterruptible power supply can protect your computer, or anything connected to it, from the changes in voltages coming from the power line. That is the essence of what a surge protector does. Although a UPS can do that and supply backup battery power to your computer in the event your house looses electricity.With an uninterruptible power supply, you can get battery life that ranges from half an hour to a whole hour of life.
Every UPS is, by definition, a big battery and a voltage inverter that converts DC power from the battery to give to your computer in AC form. However, not all UPSs work the same. With a basic UPS, you can get something like 300 watts of power to supply a fairly low end desktop computer and monitor for a few minutes before it crashes. It would also have a surge protector for protection against surges. But if you had a higher end UPS such as one that has 900 to 1000 watts of power, you can actually power a high end gaming system with a 30" monitor for ten minutes or so.
A high-end uninterruptible power supply usually includes something like an online system called a Line Interactive UPS. But lower-end uninterruptible power supplies usually don't, making them an offline UPS. With an offline UPS, you're taking the main voltage from your house and you're feeding that directly into your computer unless it goes off or plummets substantially. With an online UPS, it can handle a brown out or an occasional spike and can adjust on the fly without switching to battery mode and without exposing your computer to the harmful electricity from the power line. A brown out is when something is plugged into your house and takes enough power to cause, say, your lights to flicker a bit. Your computer will be protected from that when connected to an online uninterruptible power supply.
When a UPS starts to kick in, you can hear a bit of a ticking noise. This means that some kind of a brown out or voltage irregularity is taking place in your house's power line. Over time, such electrical anomalies can cause minute damage that shortens the life of your computer which can also lead to dead hardware. A UPS can be incredibly important for protecting the hardware in your computer. It is also useful for giving you ample time to save your unsaved work should a power outage occur.
Inverters have become one of the indispensible requisites not only for the industries but for residential purposes as well. The decreasing prices of home inverters in India have made it accessible even for the middle classes. They are also easily available with the inverter sales increasing day by day. There are also inverter service centers where you can approach in case of failures.
But before you buy home inverters you need to learn a few safety tips about inverter installation. Here are a few of them.
* Power inverter installation at homes is quite easy as they are of smaller rating and does not require much wiring.
* Choose the right location for your power inverter. Clean the area and start the inverter installation.
* Charge the inverter battery before the inverter installation.
* Find the terminals of the home inverter power source.
* Mount the home inverter in a place that has enough air circulation and make sure that the inverter battery is switched off before installing.
* Get the red wire which is the live wire and connect it to the positive input terminal of the home inverter. The other end of the live wire is to be connected to the power sources positive terminal.
* The next part of the wiring includes the setting of the neutral wire which is usually in black. Connect both ends of the neutral wire to negative terminals of the power inverter and power source.
* The wiring of your home inverter is now done. You now need to test the wiring of the power inverter by switching it on.
It is important to keep a check over the home inverter every now and then to ensure safety. If you are not sure of the inverter installation procedure, it is better to approach your electrician. This is the best safety measure you can take!
