Recently Secured by Design have updated the specification for door viewers, and in order to reach SBD specifications a door viewer must have a viewing angle of at least 120 degrees from the end of the viewer (i.e. 60 degrees at both sides). Door viewers (sypholes) are a great security accessory for your home, as no door should be opened without first checking who is on the other side. Door security is essential to ensuring a home is safe and once quality locks have been fitted it’s key to have a door viewer. Many homeowners overlook the importance of really seeing who is on the other side of the door and essentially this can actually be the best way to prevent unwanted guests, break-ins, and scams. Providing your customers with this important information will help them learn to better protect their homes and keep intruders out.Each viewer has gone through rigerous testing, and have each been tested to DHF TS002:2009 which covers Corrosion Resistance, Security (Angle of Vision), Visual Clarity, Resistance to Misting Up, Ability to Clear After Misting, Length Adjustment Range and Marking.Made with a solid brass body, and comprising of 3 plastic lenses, each syphole ensures to give crystal clear performance for years of safe, secure use. As standard, all composite door viewers are salt spray tested for a minimum of 480 hours, and comes with a 5 year inland coating guarantee against pitting and rusting (defined as 25 miles from the coast and 5 miles from a heavily populated industrial area).
