CCTV surveillance systems are often popular solutions for homes and businesses in deterring intruders and capturing suspicious activities. Depending on your usage needs, you can choose between IP, analogue and wireless systems. As an overview, security surveillance systems usually consist of security cameras and a recorder for capturing footage of your designated areas.
Understanding IP / Analogue / Wireless Surveillance System
- IP Security Systems are made of video cameras that transmit video footage via IP network. Its plug-and-play installation makes it easy for most users to set up on their own. Footage is stored using an NVR (Network Video Recorder).
Features of IP Security System:
- Easy to set up
- High-resolution video quality
- Access video footage easily via smartphone
- Needs only a single PoE cable
- Encrypted security
- Covers up to 3 times more area than analogue cameras
- Analogue Security Systems are made of video cameras that transmit video footage via a coaxial cable to a VCR or DVR. Cameras need to be directly plugged into the DVR and require power through a low voltage power cable.
Features of Analogue Security System:
- Lower cost in comparison to IP systems especially if many cameras are needed
- Consumes less bandwidth than IP camera systems
- Wireless Security Systems connect to the NVR through Wi-Fi. Wired Power is needed for each camera. Wireless systems can usually only support up to 4 cameras.
Features of Wireless Security System:
- Easy to install, no need for cables between the cameras and recorder
- Easy to relocate, good for temporary setup
- Easy to conceal without wires

Other CCTV Camera Designs: Fixed Lens / Varifocal Lens / PTZ
As its name suggests, a fixed lens camera maintains the same area view once it is set in place. You will not be able to adjust the focal length or pan and tilt movement.
Varifocal lens cameras have optical zoom to maintain video quality with focal adjustment. Of course, the more you magnify an image, the more pixelated it is. The higher the resolution of your video, the less pixelated.
Features of PTZ Cameras:
- Has optical zoom and varifocal functions
- Has in-built motors for cameras to pan and tilt
- Can Pan-Tilt-Zoom (PTZ camera) so you can cover more area with fewer cameras
- Great IR night time range
- Usually costs more due to advanced features
- Great for business and commercial spaces such as airports, train stations, stadiums, hospitals, and school campuses.
