CCTV surveillance systems
What is CCTV?
CCTV (Closed Circuit Television) usually comprises several cameras strategically placed around the home to monitor entry points and the perimeter the home. Additional cameras may survey high-value items, such as cars in a garage. A CCTV system allows you to review footage after an event has occurred, or to live-view what's happening around your home.
What are the benefits of CCTV?
CCTV can record suspicious behaviour that happens around your home, including burglary. The footage can be used to help police identify the perpetrator or their vehicle, and may even be used as prosecution evidence in court.
CCTV cameras can also deter potential intruders, who may hesitate to approach a home with a surveillance system. That said, CCTV systems are best used in conjunction with an intruder alarm system if you aim to deter burglars.
Theft aside, CCTV cameras can also be used to check on your pets, kids or elderly parents to make sure they're home safely.
How do I watch my CCTV footage?
Many modern CCTV systems deliver their footage via WiFi to apps on your mobile phone or computer. Therefore, you’ll be able to live-view your house or review past footage on your smart device anywhere with internet coverage.
Some motion detection systems can even send alerts to your phone if movement is detected when the system is armed.
How many cameras will I need?
Every home and every homeowner’s requirements are different. In general, you should aim to have a camera covering your entry points (front/back/side doors, front path, driveway, garage door) plus any valuable outdoor assets, like cars, boats or tool sheds.
"Discuss your requirements with a licensed security adviser for the best results," Dean advises. "They can help you decide what to cover."
Do fake security cameras work?
Fake security cameras are a cheap and easy way to give the appearance of security around your home. But don’t underestimate a criminal’s intelligence. Most fake or dummy cameras are easy to spot, and this will undermine your home’s overall security.
Do CCTV cameras have motion sensors?
Not all security cameras sense motion, because their main function is to capture visual footage. As a supplementary feature, however, some cameras and systems will detect motion. But as most CCTV cameras are used outside, they are prone to unwanted activations by passing cars, pedestrians, animals, wind, etc. It’s recommended to rely on your intruder alarm to detect motion and your cameras to capture visuals.
Ask a licensed security consultant about their range of cameras that use artificial intelligence to accurately distinguish between humans, vehicles and animals, avoiding unwanted alerts.
How often do DIY CCTV camera batteries need to be replaced?
DIY camera batteries will need charging every few weeks to every few months, while professionally installed CCTV cameras are constantly powered by mains power.
