About Us

Security Devices International (SDI) is a defence technology company specializing in the development of innovative next generation less-lethal 40mm ammunition. Less-lethal weapons (LLW) are also described as “non lethal”, “less than lethal”, or “compliance weapons” in industry terminology.

Why We Started SDI

SDI (Security Devices Inc.) was incorporated in 2005. The Corporation began as a research and development company focused on the development of 40mm NLW for the modern military and specialized law enforcement personnel. Our products are an alternative to what was previously available that have been found to be less effective in meeting NLW requirements.

SDI’s Family of Blunt Impact Projectiles (BIP) are designed for military, peacekeeping, homeland security, law enforcement, correctional services, and private sector security. They are ideal for crowd control scenarios and can adapt to any 40mm caliber standard issue weapons and grenade launchers. Our patented rounds have been developed for accuracy at longer ranges in order to ensure the greater safety of the user. They provide an effective means of incapacitating subjects without causing lethal injury. This is due to the unique design of the BIP that uses an innovative collapsible head to mitigate kinetic energy, thus making it highly effective even at a very close range.

SDI less-lethal weapons are a safer and more accurate alternative to previous solutions such as 12 gauge stabilizer rounds, 37/40mm rubber bullets, wooden batons, 40 mm rubber ball canisters and bean bags. SDI now offers more efficient alternatives to these NLW used for crowd and riot control. SDI develops and markets payload delivery variants of its ammunition that can be adapted to contain liquid and gas agents. SDI’s NLW payloads can also carry liquid and powdered marker rounds to identify organizers and agitators of riots and unlawful assemblies.

As well, the company has designed a Wireless Electric Projectile (WEP) that uses mini-harpoons to affix a bullet to a target’s clothing or body. The 40mm bullet contains an electrical system that releases a charge, inducing a muscle spasm that causes the target to fall to the ground helpless. SDI has brought together a strong management team that has the ability, skills and knowledge to market its unique compliance ammunition to a variety of potential users, including the Military, Police, Correctional Services, Private Security and Homeland Security Agencies.
