Both Analogue and IP CCTV systems do a brilliant job at securing your property.
Analogue CCTV systems are very cost-effective, come through to your phones, and you can still achieve 8mp 4k UHD analogue images giving you around 14-15m that you can get the fine detail like faces and number plates.
IP CCTV Systems are the future of CCTV, with ever evolving technology being implemented, even after installation via firmware upgrades. Being ran on a data cable future proofs these systems, and they host advanced features such as built in AI that can tell the difference between humans and vehicles as oppose to any movement, which reduces false triggers on notifications, have features like facial recognition, and the 8mp 4k UHD digital images on this system gives you around 25-30m that you can get the fine detail like faces and number plates.
