IP security camera Jargon Buster

Gigabit Switch. Typically we recommend having POE (Power over Ethernet) switches where the camera allows. These send power through the network cable removing the need to get power to each camera.

Infrared  - The infrared illuminators will emit invisible light, enabling you to monitor an area that’s completely dark, up to a range of 20m.

Infrared Cut Filter (ICR) – A filter that can block infrared while still passing visible light.  Enables enhanced daytime images while also allowing the camera to be used at night.

Network Video Recorder (NVR) – This will manage and record images from the various cameras, typically to a hard disk.  They can also record to a recordable DVD and the cloud.

Remote Viewing - Computers and some mobile devices can view the cameras remotely for the ultimate in peace-of-mind.

Pan, Tilt, Zoom (PTZ) cameras – The ultimate in surveillance technology.  These cameras are not limited to viewing the area they are pointed to when installed.  They can pan 360˚, tilt up and down and zoom in and out to provide maximum coverage of large areas.

Power over Ethernet (PoE) – This is the use of a data line instead of the usual mains power supply to get power to the cameras.  Mains power supply can fail due to power cuts, or simply being unplugged, and this would cease recording.  PoE overcomes this.  It can also be simpler, and therefore cheaper, to install.

UPS. The UPS (Uninterruptible Power Supply) means that during a power cut the DNR can continue to record. UPS can be used for switches as well so that cameras can continue to record during a power cut also.

Wired Cameras – Wired cameras can be powered using PoE (see above) and do not need their own power supply.  They will continue to record during power cuts as the UPS (see above) enables them to do so.

Wireless Cameras – These need their own power supply, which could be as simple as being plugged into a wall socket.  They transmit their recordings back to the recorder wirelessly, and are therefore more suitable for being moved between various locations.
