How many days does a CCTV hard disk record?

For 2MP cameras on H.265, recording 24 hours a day. On H.265+, four cameras keep about 13 days per terabyte. Recording only on movement in a quiet house stretches 1 TB to about 33 days. 4MP uses about 60% more space than 2MP, and 4K about three times as much.

Which CCTV system fits you

Wi-Fi cameras

No cable runs: each camera records to its own microSD card and needs a power point and a good Wi-Fi signal. You watch on the EZVIZ app.

Best for one to three cameras in a flat, a room or a small shop.

EZVIZ cameras

DVR with analog HD cameras

The lowest-cost wired set for 2MP cameras. Each camera runs on 3+1 cable, which carries video and power together, to a DVR that records to a surveillance hard disk.

Best for homes and shops with four to sixteen cameras.

NVR with IP cameras

For 4MP and 4K cameras. One network cable per camera carries video and power (PoE), and IP cameras have smarter motion detection.

Best for shops, offices and bigger houses.

Plan my system

How the planner works it out

These are planning estimates. They lean to the safe side, so the disk you buy should last at least as long as the planner says.

Space per camera on H.265: about 2.5 Mbps for 2MP, 4 Mbps for 4MP and 8 Mbps for 4K. H.265+ uses about 40% less and H.264 about twice as much. One camera at 1 Mbps for 24 hours fills 10.8 GB.
Wi-Fi cameras use EZVIZ's own figures: at most 21.4 GB a day for a 1080p camera and 42.8 GB for a 4MP camera, so a 128 GB card holds about 6 days of 1080p.
About 90% of a hard disk's label size is usable for video.
Recording on movement: about a quarter of the day is recorded in a quiet place, and about 60% in a busy one.
Cable: your distance for each camera plus 10% for bends. 3+1 cable comes in 90 m rolls and network cable in 305 m boxes. A single network cable run stops at about 100 m.
Power: about 1 A at 12 V per analog camera; 6 W per IP camera on PoE, or 8 W with colour night lights. Watching live on a phone uses about 0.5 Mbps of upload per camera.

CCTV planning questions

How many days will a 1 TB hard disk record CCTV?

With four 2MP cameras on H.265 recording 24 hours a day, a 1 TB disk keeps about 8 days and a 2 TB disk about 16. On H.265+ it is about 13 days per terabyte, and recording only when there is movement in a quiet house stretches 1 TB to about 33 days. Put your own cameras into the planner above to see your figure.

How many CCTV cameras do I need for my house?

Count the spots you want recorded. Most houses need about four cameras: the main gate, the front door, the back and the parking. A small shop usually needs three or four. Pick a recorder with a spare channel or two, so you can add a camera later.

DVR or NVR: which one should I buy?

A DVR records analog HD cameras over 3+1 cable and is the lower-cost wired choice for 2MP cameras. An NVR records IP cameras over network cable that carries power too (PoE), and is the usual choice for 4MP and 4K cameras. The planner picks one from your camera count and picture quality, and you can switch it.

Should I buy Wi-Fi cameras or a wired CCTV system?

Wi-Fi cameras suit one to three cameras where running cable is hard. Each records to its own microSD card and needs a power point and a strong Wi-Fi signal. For four or more cameras a wired system is more reliable, and its recorder keeps recording to the hard disk when the internet goes down.

Will CCTV keep recording during a power cut?

Only if the recorder and the camera power supply are on backup power. A four-camera wired set draws about 34 W, so a small UPS keeps it recording through short cuts; for long cuts, connect it to your home inverter. The planner shows the power draw for your set.

Can I watch my CCTV cameras on my phone?

Yes. Hikvision recorders work with the Hik-Connect app and EZVIZ cameras with the EZVIZ app, as long as the recorder or camera is online. Watching live uses about 0.5 Mbps of upload per camera, so four cameras need about 2 Mbps.

Do you install CCTV?

Yes. Our team installs CCTV systems. Make a plan here, keep installation switched on and send it to us on WhatsApp, and we reply with one price for the parts and the installation.
