4MP is the sweet spot for most CCTV systems: at 2560 × 1440 it records roughly twice the pixel detail of a 1080p camera — enough to read a number plate at the end of a drive or recognise a face across a shop — without the hard-drive and bandwidth demands of 4K. Zenith Security Co stocks 4MP IP cameras from HiLook by Hikvision, Hikvision, Dahua and Honeywell in turret, bullet and dome bodies, including ColorVu 3.0 models with Smart Hybrid Light that record in full colour at night.

Popular 4MP choices

• HiLook IPC-T249HAA-LU — 4MP ColorVu 3.0 turret, IR or colour night vision, our most recommended all-rounder.
• HiLook IPC-B149HAA-LU / IPC-D149HAA-LU — the same camera as a bullet or a dome.
• HiLook IPC-D140HA / IPC-B140HA — budget 4MP dome and bullet with 30m IR.
• HiLook IPC-C340HA-D/W and IPC-B140HA-D/W — 4MP Wi-Fi cameras with two-way audio for cable-free installs.

All 4MP cameras here are PoE (or Wi-Fi where stated), work with HiLook and Hikvision NVRs, and support ONVIF. Pair four of them with a 4-channel PoE NVR and a 2TB surveillance drive for a complete small system.
