Lighting Stand

There are two things that intruders do not like – noise and bright light.
The first makes it difficult for them to hear people approaching, and makes a convincing case for installation of interior sirens (sound bombs) in the alarm systems. However, this is a topic for another day.
The latter means it can be easily and is possibly the most effective deterrent. Safety lighting may be used in conjunction with closed circuit television to make better photos.

Safety lighting can be used inside and out, and everything said here applies to anyone. Remember, however, that outdoor lights should be approved for outdoor use, although there is nothing to prevent indoor use.
Many of the locals to leave the lights on all night. If you do this be sure to that low energy lighting such as fluorescent lighting or sodium is used, otherwise there will be no electricity consumption of large size.

Switched PIR Lighting

A PIR or passive infrared detector red lights when motion is detected body heat. Therefore detect human beings but also animals such as cats up. The most popular form of security lighting is built into a RIP, which turns on the light if some-one night is approaching. RIP frequency can be adjusted to 3 things – the light level at which to start work, the time during which they remain in (usually 20 seconds to 10 minutes) and sometimes the sensitivity or range over which they work (typically 4 to 12 meters). They are usually physically adjustable so that it can be noted below for reduce the range, and side to provide coverage over certain areas. They are more sensitive when the person comes through your area of detection, in a straight line they.
When choosing a location should be at least 2.5 m above the ground, so they are not easy to handle, well away from any heat source, as an escape from central heating and detection zone should not include a path to the end of the property.
Many have a PIR over-ride mechanism, so that light can be switched on for 8 hours continuously.
Halogen, ranging from 150 to 500 or, sometimes 1000W, are the most common security lights with PIR, but others types of lighting fixtures are also available.
Low energy bulbs are best avoided, because some do not last long and can reduce the life of the RIP and not reach full brightness immediately, what is desirable in a security light.
Projectors can be disruptive to neighbors, if they shine on their property, especially through windows, so viewing and adjustment must take this into account. Usually can be adjusted independently from the PIR to avoid pointing outside ownership of other peoples.
PIR lights must be connected via a fused spur switch, so that could be isolated for maintenance, as change a light bulb.

Dusk to Dawn Lighting

Instead of a RIP, these lamps usually have built in photocell, which changes in them at dusk and stay all night until dawn. Because they are for long periods, most light bulbs use energy. These do not as powerful as lighting projectors. Some light bulbs photcell have been built in, so you can put in any facility that is large enough to take them. If you use these, make sure the photocell is exposed to light and not obscured by the installation of light, otherwise it will come during the day.

Regular outdoor lighting accessories Switched

These include floodlamps without RIP, and all other forms of lighting.
There are several ways these can be changed to turn them in security lights.

1. Using an ordinary light switch to turn them on manually. It may be useful light for convenience, but useless if they are not there to light them.

2. Using an external RIP. Stand-alone PIR can be used to light the lamp. There will to be the wiring of the light is going to RIP. This is useful if the light is the best outside the detection zone. All the above applies here on PIR. External PIR are often better than those built on. Some have a 360degree detection area, but only up to 180deg. is required when mounted on a wall.

3. Using an external photocell.

4. Using a time switch. The easiest way is to use a plug-in timer. These are inexpensive and easy to use. Light is equipped to plug, that plugs into the timer. This can be adjusted to the light to go in and out of what the timer is set. If the light is out, the or timer must be within, or in a waterproof outdoor sockets.

5. Using a random lamp holder switch. This is mainly used for internal use and outsders gives the impression that some-one is in the house lights change.

6. Using a key fob remote. The projector controlled the radio is powered remotely using a small key chain transmitter. This can be kept on a keychain and operated from a car, or, say, a bedroom, to change in an external projector.
