Quality keyed lock
A lock that is sturdy, well-made and will stand the test of time and force. A good quality lock will usually be key-operated from both sides. Look for locks that meet the Australian lock standard.
A three-point (or triple) lock has one central lock, plus an internal rod that connects to two additional locks, one above the main lock and one below it. It is significantly more secure than a single lock as it locks at three points on the door jamb.
Deadbolts have no spring activation and are thicker and heavier than spring latches. The locking bolt is typically made of steel or brass, is not rounded or angled at the end and extends about 25mm into the door frame. It can be either key-locked from the inside or with a turning mechanism.
Electronic, smart or keyless locking An electronic lock that doesn’t use a traditional key. You gain access via a keypad located at or near the door, which requires entering a numeric code; a fingerprint scan; or remotely via a smartphone or electronic control (you can also monitor who comes and goes).
One-way vision meshA mesh for screen doors that restricts vision to one-way so that people looking from the outside, cannot see in.
Motion sensorA device that detects movement in an area is where they shouldn’t be (eg, an intruder) and sends an alert to your control panel, which alerts your monitoring centre.
Monitored alarm systemA monitored system alarm will alert a call centre if the alarm gets triggered and this call centre will contact the police.
Unmonitored alarm systemThis system sets off a loud siren inside and outside the house when the alarm is tripped. This system relies on your neighbours nearby to call the police if you are not home.
Window and door sensorsDoor and window sensors will sound an alarm (emit a siren, trigger your home security system or sending you an alert on your phone) when someone picks a lock or climbs through an open window or door.
