4MP Kits: quick answers
How many days of footage will a kit in this range keep?
It depends on the drive and on how many cameras record, at what resolution. As a guide for continuous recording, each terabyte holds about 23 days at 4MP, and about 11 days at 4K for one camera. The median kit in this range is estimated at 29 days. Every kit's card states its own estimate, and motion-only recording keeps footage for longer.
What is the difference between channels and cameras?
Channels are how many cameras the recorder can take; cameras are how many come in the box. Recorders in this range have 4 to 32 channels. Spare channels let you add cameras later without changing the recorder.
What is in the box?
A recorder (an NVR for IP kits, a DVR for Turbo HD) and its matched cameras, checked against each other. Every kit in this range includes a hard drive. The exact contents, every part with its model number, are listed on each kit's own page.
4MP Kits: complete NVR/DVR and camera bundles for CCTV installs
A 4MP kit pairs a recorder (NVR or DVR) with pre-matched 4MP cameras and a fitted hard drive, so channel count, PoE budget and storage arrive as one coordinated spec sheet rather than three separate purchases.
The range spans DVR kits (e.g. DVR-8CH-HYL8MP, Dahua DH-XVR5108H-4KL-X-8P) using Prolux PXC-612C4W-A-POC 4MP cameras, through to PoE NVR kits from Hikvision, Tiandy, Longse and Prolux running Hikvision DS-2DE4425IW-DE and DS-2DE4A425IW-DE 4MP camera lines. Channel counts run from 4 to 32, with HDD capacities of 6TB or 14TB fitted as standard per kit.
How to choose
- Channel headroom: match NVR/DVR channel count to current camera count plus spare ports for future additions — e.g. a 32-channel NVR kit here ships with only 4–6 cameras populated.
- PoE vs DVR: PoE NVR kits (marked "P" or "POE" in the model code) power cameras over the same cable; DVR kits pair with the PXC-612C4W-A-POC camera instead.
- Storage: confirm the bundled HDD (6TB or 14TB) suits your retention needs before adding extra channels of footage.
- Cross-brand pairing: several kits mix recorder and camera brands (e.g. Longse NVR with Hikvision cameras) — check the exact model pairing per kit rather than assuming same-brand throughout.
4MP Kits — frequently asked questions
What's included in a 4MP kit?
Each kit bundles a recorder (NVR or DVR), a set of 4MP cameras, and a fitted hard drive (6TB or 14TB depending on the kit).
What's the difference between the NVR and DVR kits in this range?
NVR kits generally use PoE to power cameras over the network cable, while the DVR kits here pair with the Prolux PXC-612C4W-A-POC 4MP camera instead.
Can I add more cameras later if I choose a higher-channel NVR?
Yes — several kits, such as the Hikvision DS-7732NI-M4/24P 32-channel NVR kits, ship with only 4–6 cameras installed, leaving spare channels free for expansion.
