CCTV Camera Playback Not Working on Your DVR or NVR

12 min read · Oct 20, 2026

When cctv camera playback not working is the problem but live view looks fine, the fault is usually on the recorder, not the camera. The four usual causes are a hard drive the recorder cannot see or has never formatted, a record schedule that is switched off, a system clock set to the wrong date so the footage is "hidden" under another day, and a drive that has already overwritten the period you want. Work through the checks below in order; the first two are quick and are the usual culprits.

This guide is about recorders: a DVR (for wired analogue cameras) or an NVR (for network and WiFi cameras). If your camera records to a memory card inside it, the steps are different and are covered in why a camera is not recording to its SD card. If recordings exist but you are not sure how to read the timeline in the app, start with how to watch playback and save a clip.

First, work out what "not working" means

Different symptoms point to different causes. Before you change anything, note which of these you see:

"No record file" or an empty timeline for every camera and every day. The recorder is not storing anything at all. Look at the hard drive (Check 1) and the record schedule (Check 2).
One camera has footage, another has none. The drive is fine; the missing camera has no schedule, or its channel is set to record on an event that never triggers.
Footage exists, but not for the day you need. Either the clock is wrong (Check 3) or the drive is full and has overwritten older days (Check 4).
The timeline shows coloured bars, but playback spins, freezes or shows black. Recording works; the problem is reading it back, often a failing drive, a remote connection that is too slow, or a stream setting the viewer cannot decode.
Playback works on the recorder's own monitor, but not in the phone app or on a computer. The recordings are fine. The problem is remote access, covered near the end.

Write the symptom down. It saves you from changing five settings at once and then not knowing which one fixed it.

Check 1: is the hard drive detected and formatted?

A recorder with no usable drive will show live video perfectly and record nothing. It is a common cause on new installs and after a drive has been swapped.

On the recorder's own screen (connect a monitor and mouse if it is a headless box), open the main menu and look for a section called Storage, HDD, Disk management or similar; names vary by model and firmware. You should see one line per installed drive with a capacity and a status.

What the status tells you:

No drive listed at all. The recorder cannot see it. Power the recorder off, unplug it at the wall, open the case and reseat both the data cable and the power cable on the drive. Make sure the drive is the type and size your recorder supports; the manual or the label lists the maximum capacity per bay.
Listed as "uninitialised", "unformatted" or "abnormal". The drive is detected but not prepared. Select it and choose Format or Initialise. This erases anything on the drive, so only do it on a new drive or one with nothing you need.
Listed as "normal" but with zero free space and no overwrite. The drive is full and the recorder has been told to stop rather than loop. See Check 4.
Listed as "error", or it keeps dropping off the list. The drive is likely failing. Copy off anything you need first if you still can, then replace it with a drive rated for continuous surveillance recording; ordinary desktop drives are generally not designed to write around the clock.

Safety note: the recorder's power supply is mains-connected. Always switch it off and unplug it before opening the case. If the recorder sits in a ceiling space, a cabinet high up or a rack you cannot reach safely, ask a qualified installer or electrician rather than working from a chair or a ladder alone.

Check 2: is the record schedule actually on?

A formatted drive is not enough; each camera channel needs to be told when to record. Many recorders ship with recording enabled by default, but a factory reset, a firmware update or a newly added camera can leave a channel with an empty schedule.

Open the Record, Recording or Schedule menu and select each camera channel in turn. You will usually see a weekly grid:

Check that the channel's recording is enabled. There is often a separate on/off switch above the grid.
Check the grid is filled in for the hours you care about. A blank grid means no recording at any time.
Check the type of recording. Continuous (sometimes called "normal" or "timing") records all the time. Motion or event recording only writes when the camera detects something, so quiet hours stay empty on purpose.
If the channel is set to motion only, open its motion detection settings and confirm motion detection is enabled and the detection area covers the scene. A motion schedule with motion detection switched off records nothing.
Repeat for every channel, including cameras you added later. A new camera does not always inherit the schedule of the others.

After saving, wait a few minutes, then open playback for the current hour. If a fresh bar appears, recording works and the missing older footage was simply never captured.

Check 3: is the recorder's clock right?

If the recorder lost its time after a power cut, or the time zone is wrong, footage is being recorded but filed under the wrong date. You search last Tuesday and find nothing, because those hours are stored under a date years ago or hours away.

How to check:

Look at the date and time stamped on the live view. Compare it with your phone.
Open System, General or Time settings and confirm the date, time, time zone and daylight saving setting.
If the clock was wrong, search playback across a wider range. Try the date shown on the recorder's clock when the problem began, or the default date a reset sets (often the start of a year). Your "missing" footage is frequently there.
To stop it happening again, turn on automatic time sync (often called NTP) if your recorder offers it and is connected to the internet. Some recorders also have a small backup battery on the board that keeps time during power cuts; if the clock resets after every outage, that battery may need replacing.

Fixing the clock does not move old recordings to the right date. Those files keep the time stamp they were written with, so note the offset when you export them as evidence.

Check 4: has the drive already overwritten the footage?

Recorders normally loop: when the drive is full, the oldest recordings are deleted to make room. That is usually what you want, but it means footage has a shelf life. If you go looking for an incident after that window has passed, it is gone, and no setting brings it back.

To find your real history window, open playback and step back day by day until days stop showing footage. That earliest day is your current limit for CCTV footage storage.

How long a drive lasts depends on drive size, number of cameras, resolution, frame rate, compression and whether cameras record continuously or only on motion. There is no single figure. As a worked example only: if one camera's stream averages around 1 GB per hour, four cameras recording continuously would use roughly 96 GB a day, so a 2 TB drive would hold somewhere around three weeks. Your own numbers can be very different, so measure them by looking at how many days your drive actually holds.

If the window is shorter than you need, your options are:

Switch quiet cameras to motion recording so they only write when something happens.
Lower the recording stream (resolution or frame rate) on cameras where detail matters less.
Fit a larger drive, or a second drive if the recorder has a spare bay.

If you are still deciding between a recorder and memory cards for a small WiFi setup, the trade-offs on CCTV storage are laid out in whether you need an NVR or an SD card is enough.

Check 5: the camera is added, but its channel records nothing

On an NVR, a camera can appear in live view through one route and still not be recording on the channel you expect. Things to look at:

Channel status. In the camera or channel list, a green or "online" status means the NVR is pulling video. "Offline" or a warning icon means it is not, and nothing will be recorded.
Password changes. If someone changed the camera's password after it was added, the NVR loses access, often after the next restart or power cut. Update the password in the channel settings.
IP address changes. A WiFi camera that gets a new local address from the router will vanish from the NVR. Giving it a fixed address prevents this; the steps are in adding a Yoosee camera to an NVR.
Stream settings. Recorders usually record and play back the camera's main stream. If that stream uses a format or bitrate the recorder struggles with, playback can stutter or show black even though recording ran. Try a lower bitrate or a more widely supported video format on the camera, then check a fresh recording.

When playback only fails in the app or on a computer

If playback works on the recorder's monitor but not remotely, the recordings are safe and the problem is the connection:

Check the recorder is online. In the app, the device should show as connected. If live view from outside works but playback does not, the upload speed at the site is often too low; playback needs more bandwidth than a small live preview.
Switch to the lower-quality stream in the playback screen if your app offers it.
Try one camera at a time. Playing back several channels together multiplies the data the site has to send.
Update the app and the recorder firmware; menu names may differ slightly between app versions.
Test on the local network. Connect your phone to the same WiFi as the recorder. If playback works there and not on mobile data, the issue is internet upload at the site, not the recorder.

When to get help

Stop and ask for help, rather than continuing to experiment, when:

The drive keeps showing an error after you reseat the cables, or the recorder clicks, restarts on its own or will not finish booting.
You need footage for a police report or insurance claim. Do not format, reset or replace anything until a copy has been made; every change risks the files you need.
The recorder or cables are in a place you cannot reach safely, or the wiring involves mains power.
Several cameras drop offline together, which often points to a network switch or power supply fault rather than the recorder.

A qualified installer can test the drive, check the wiring and export footage properly. For legal questions about who may access recordings, check local rules.

Install or resell cameras?

Most playback complaints after an install trace back to set-up steps that are easy to skip on the day. A few habits prevent them:

Format the drive in the recorder during the install and confirm its status reads normal before you leave.
Open the record schedule for every channel and fill it in, then show the customer a fresh bar on the playback timeline for each camera.
Set the time zone and turn on automatic time sync, and stamp the correct time on the image.
Give every network camera a fixed local address so a router restart does not break recording.
Tell the customer, in writing, roughly how many days their drive holds at the settings you chose, and how to check it themselves.

Frequently asked questions

Why does my DVR say "no record file" when the cameras show live video?

Live view comes straight from the cameras, while playback reads from the hard drive. "No record file" means nothing was written for that channel and time, so check that the drive is detected and formatted, that recording is enabled for that channel, and that the clock shows the right date.

Can I recover CCTV footage after the drive has overwritten it?

In practice, no. Once the recorder loops over a period, the old data is replaced by new recordings. Specialist data recovery is sometimes attempted on drives that failed suddenly, but overwritten footage is generally treated as lost, which is why exporting important clips quickly matters.

Can I move a recorder's hard drive to a computer to watch the footage?

Usually not directly. Many recorders write to the drive in their own format, so a computer may not read it or may offer to format it, which would erase the footage. Export clips from the recorder to a USB stick instead, and never accept a format prompt on a drive that holds evidence.

Why does playback show footage at the wrong time of day?

The recorder's clock or time zone is off, or daylight saving was set incorrectly. Correct the time settings and enable automatic time sync; older recordings keep their original time stamps, so allow for the offset when you search or export them.

Does a power cut stop the recorder from recording?

Yes, while the power is off nothing is recorded, and a recorder without a working clock battery may also come back with the wrong date. A small backup power supply for the recorder and the network equipment keeps recording going through short outages.
