Home Security Systems

Home Security Systems

If you are thinking of ways to better secure your home and property from theft or damage, CCTV, alarms, safes, and motion or smoke detectors are all good options. We have quality home security equipment from trusted companies such as EVOLVEO, iGet, KGUARD, AeoTec, and others.

Cameras and alarms

Camera systems and GSM alarms are effective security solutions for houses, apartments, offices, and shops. For example, a camera system can include four EVOLVEO CCTV cameras with sufficient wiring for monitoring large objects. Wireless alarms are easy to install, and wireless motion sensors are easily placed inside or outside the house at appropriate distances. If the sensors pick up movement within the space, the system automatically calls or sends an SMS message to multiple numbers. 

Digital safes and door peepholes

A digital safe is a smart choice for keeping your valuables safe and secure. For example, G21 vaults are protected by a PIN lock, are very simple to use, and feature a high-quality metal design. Digital safes are suitable for depositing money, jewelry, passports and small electronics. Another security option is a motion detector that senses a person at a distance of up to several metres. It automatically records images on a memory card, as well as the date and time of the recording, so you'll know exactly who visited and at what time.
