01What the video shows
The video opens on the before: an old camera on a building parapet with its cables joined in the open, the joints exposed to dust, rain and sun. Installations like this are behind many cameras that flicker, go offline in the rain or stop recording without anyone noticing.
It then shows the IP CCTV system that replaced it, with cameras on proper network cabling and connections protected, so the system can be relied on and maintained.
02Why IP CCTV
IP cameras send a digital video stream over network cable to a network video recorder (NVR). With PoE (Power over Ethernet), one cable carries both video and power, which means fewer joints and fewer points of failure. IP cameras also offer higher resolutions and smart features like human and vehicle detection.
Compare the two architectures in HD CCTV vs IP CCTV and see how PoE works.
03Upgrading an existing system
You don't always need to replace everything. An upgrade starts with an assessment: which cameras, cables and recorders can stay, and which parts are causing faults. Exposed joints, undersized power supplies and failing hard drives are the usual culprits.
Qyvea works on systems installed by other companies too. See CCTV installed by another company and upgrading an existing security system.
04Frequently asked questions
Why do exposed cable joints cause CCTV faults?
Water and dust get into the joints and corrode them, causing flickering, lost video or cameras going offline, especially after rain.
Can I upgrade to IP cameras and keep my old cables?
Sometimes. Coax cables usually need replacing for IP, but routes and conduits can often be reused. An assessment shows what can stay.
Is IP CCTV better than analogue HD?
IP gives higher resolution, smart detection and simpler cabling with PoE. HD-over-coax can still suit small systems or reuse of existing coax.
