CCTV SURVEILLANCE SYSTEM
A closed-circuit television camera (CCTV) is an integral part of a TV system that is used for security and surveillance reasons. They are a private way to monitor what is happening in and around your home. Cameras are strategically placed so you can observe certain areas of your house and property. The cameras communicate with monitors and the images are shown only to the people who are designated to see it. This provides an optimum level of privacy and security. This system is reliable, which means it is often used for traffic monitoring, building and grounds security, medical facilities and other important purposes.
HD VS IP CAMERA
If you want to use surveillance video for license plate reading, facial recognition, or evidence of a crime, you'll want a camera with high definition. But with such a wide range of cameras available, how do you know which one is right for you?
Analog cameras have been used in surveillance systems for over 30 years. The surveillance industry is moving away from CCTV and toward IP, but many businesses are still using analog systems. If you want to continue using your analog equipment but want the HD resolution of newer cameras, you'll want to switch to HD analog cameras.
HD analog cameras measure resolution in pixels instead of TVL, which older cameras use. Benefits of HD analog include lower costs than IP cameras and easy installation like any other CCTV camera.
IP cameras are the newest development in surveillance, coming into popularity in the last few years. These cameras use your network to connect to your system and share data. This allows the system to grow and change with better flexibility - less reliance on cables and power outlets gives you more control over where cameras are placed
security alarm system
In this instance, we’re talking about home security systems, which are networks of integrated electronic devices working together with a central control panel to protect against burglars and other potential home intruders.
A typical home security system includes:
A control panel, which is the primary controller of a home’s security system
Door and window sensors
Motion sensors, both interior and exterior
Wired or wireless security cameras
A high-decibel siren or alarm
How does a security system work?
Home security systems work on the simple concept of securing entry points into a home with sensors that communicate with a control panel or command center installed in a convenient location somewhere in the home.
The sensors are typically placed in doors that lead to and from a house as well as easily accessible windows, particularly any that open, especially those at ground level. Open spaces inside of homes can be secured with motion sensors.
Control Panel: The control panel is the computer that arms and disarms the security systems, communicates with each installed component, sounds the alarm when a security zone is breached, and communicates with an alarm monitoring company.
They typically feature a touch pad for easy programming and interaction, is where pass codes are entered to arm and disarm the system, can work on voice commands, and can be programmed to work with wireless remote controls called key fobs.
Door and Window Sensors: Door and window sensors are comprised of two parts installed adjacent to each other. One part of the device is installed on the door or window and the other on the door frame or window sill. When a door or window is closed, the two parts of the sensor are joined together, creating a security circuit.
When the security system is armed at the control panel, these sensors communicate with it by reporting that the point of entry is secure. Should a monitored door or window suddenly be opened, the security circuit is broken and the control panel interprets this as a breach of a secured zone. A high-decibel alarm is sounded and in most instances the alarm monitoring company is automatically notified.
Motion Sensors: These security components, when armed, protect a given space by creating an invisible zone that cannot be breached without sounding an alarm. These are typically used to protect rooms containing valuables, as well as areas less frequented in larger homes.
