Security lighting - protect your premises

Author: Glenn Harper
Published: September 1, 2014

Whether you're safeguarding a home or a business premises, security lighting is one of the more effective measures you'll take against unwanted visitors. Before investing in security, try briefly adopting a criminal mindset so you can identify vulnerable parts of your building. Look for easy areas of concealment near doors and windows and trim any trees or shrubs that offer a natural hiding place or obscure vision.

As well as good security lighting, consider installing alarms, full security systems, CCTV, perimeter fencing and warning signs. Ensure your locks are sturdy. Sliding glass doors are a common unlawful entry point into homes. To counteract this, they can be fitted with dowel rods, security sensors, and shatter alarms. Screws and washers are sometimes inserted to prevent such doors being hoisted from their frame.

Lyco stocks various products to help thwart intruders and vandals, but we'll primarily discuss security lighting.

Sensors

There are two types of sensor typically used in outdoor security lights: PIR sensor and photocell (commonly called a dusk-to-dawn sensor).

The PIR sensor is essentially a motion sensor that detects changes in IR radiation. Any movement within a given range triggers light for a short, often adjustable duration.

A photocell measures ambient light levels and triggers light on and off at dusk and dawn, respectively. This creates the impression that a property may be occupied, acting as a useful deterrent.

Light technologies

Take a closer look at the Sky Saviour 230W Halogen FloodlightAll lighting technologies have particular advantages and disadvantages, which may affect your buying decision when choosing security lights. Here are some of the relevant factors:

  • Halogen lights may not be the most energy efficiency, but their colour rendering is unsurpassed by other artificial light sources. This mixture of attributes lends itself well to PIR security lights, where running costs are of secondary importance. As an omnidirectional light source, halogen can cause light pollution, but this is well controlled in products such as the Byron Sky Saviour 230W Halogen Floodlight with PIR sensor.
  • Low-energy fluorescent lights are rarely used with PIR sensors because of their warm-up time, but this is less of an issue with dusk-to-dawn light sensors, where immediate bright light isn't necessary. The ASD Horizon Bulkhead offers automatically tripped overnight lighting using an economical 2D fluorescent lamp.

  • LED lighting offers numerous advantages outdoors, including reliable low-temperature performance, immediate full-power light (useful with PIR sensors), resistance to shock or vibration, and a naturally directional output that reduces light pollution. The Selene Solar Spotlights, for instance, can light an area at a distance of 20 metres with minimal light wasted outside of the spotlight beam.
  • Sodium lamps are often used in security lighting. They offer incredible energy efficiency, though colour rendering is relatively poor. A SON lamp allows some identification of colour, while a SOX lamp produces a monochromatic light that forfeits colour but heightens human perception of contrast. The Dextra 400W SON Floodlight with Photocell lights very large outdoor areas with a performance that may easily exceed 120 lumens per watt. It is ideal for industrial areas, building perimeters and car parks.

Home security lights

Security lights for the home needn't be expensive, either to buy or run. The Coach Wall Up Lantern is available with or without a PIR sensor. A PIR light is useful for legitimate entry into a home as well as deterring intruders, and it saves the expense of running a permanently switched fitting.

Take a closer look at the Coach Wall Up LanternThe Nemi Globe Wall Light uses a photocell to automatically light the outside of any home overnight and switch itself off in the morning. This fitting is IP44 rated, which is a good all-round specification for rain proofing and resistance to dust.

Lighting doesn't get any cheaper to run than when it's solar-powered, with LED development opening up a whole new market in this area. LEDs are a low-voltage light source, so they feed very efficiently off a solar-charged battery and need remarkably little power. The Evo15 Solar PIR Utility Light is a security light that is free to run and can be discreetly installed outside the home.

Business security lights

Take a closer look at the SON Wall Light with PhotocellThough there aren't any strict definitions, business security lights will often be plainer in design and stronger in output — different to residential lights in ways you'd expect. The SON Wall Light with Photocell, for instance, is another fitting that exploits a high-pressure sodium lamp for its huge lumen output and relatively low wattage. It is suitable for most outdoor industrial environments, automatically controlling overnight light and resistant to dust and jets of water.

A more directional security light, triggered by movement, is the ESP Nighthawk LED Security Floodlight with built-in PIR sensor. This 12W luminaire has a 10-metre, 160° range and projects a powerful 1100 lumens of light. Its Nichia LEDs have a mighty 91 lumens-per-watt output, which makes the manual override facility all the more attractive; this is an economical floodlight for general use, too. Nighthawk floodlights can be configured in a slave system, where multiple fittings are triggered by one PIR sensor or photocell.

Take a closer look at the Guardcam Security FloodlightAlso from ESP is the Guard-Cam Security Floodlight, which not only lights up intruders with a powerful halogen lamp, but also records them with video or still images. An audio mode allows playback of a pre-recorded warning to say “you are being recorded by a security camera” and also has a barking dog option. You can even record your own politely phrased messages.

CCTV

The presence of cameras is enough to dissuade most opportunist intruders from committing crime and gives any property owner peace of mind. Lyco sells a wide range of CCTV equipment, including convenient kits like the ESP CCTV Combi Unit with 4 External Cameras. Infrared cameras are often used, which project invisible IR light to effectively see in the dark as well as functioning normally during the day.Take a closer loko at the CCTV Combi Unit with 4 Cameras

Our CCTV security systems can be remotely monitored from PCs, tablets, or smartphones, with special apps available for iPhones or Android phones. Email alerts can also be set up, so you'll immediately know if the security system has been set off.

Entry systems and locks

To supplement any security lighting or CCTV measures, Lyco offers a range of door entry systems, door locks, and bolts and padlocks. These help protect your property during normal hours of business as well as overnight.

A false sense of security

Most of us are guilty of occasionally leaving windows open, not bothering to switch on alarms, or concealing keys in obvious places. Contrary to the popular saying, criminals rarely return to the scene of the crime. Avoid making their job easy the first time round.
