DVR and NVR repair . NYC and tri-state

NVR not recording? We repair the recorder and recover the footage.

Live view works but nothing is saving, the recorder will not boot, footage disappears before you can review it, or the drive shows errors. We diagnose, repair, and recover footage where the drive is still readable.

WHICH PROBLEM IS YOURS? 6 patterns

RECORDER · LIVE VIEW, NOTHING SAVING

WHERE IT USUALLY BREAKS

Drive Power Firmware Cooling Settings Recovery

Every camera shows on the recorder, but there is no footage when you look back. A failed drive, a write error, or firmware stopping the record process.

FIRST THING WE CHECK

Drive status and the record schedule.

All patterns 06

RECORDER · 01 / LIVE VIEW, NOTHING SAVING

Live view, nothing saving

Every camera shows on the recorder, but there is no footage when you look back. A failed drive, a write error, or firmware stopping the record process.

FIRST THING WE CHECK

Drive status and the record schedule.

RECORDER · 02 / WILL NOT BOOT

Will not boot

The power light may come on, but it never reaches live view or shows a boot error. A failed power supply, a dead drive or corrupted firmware. Many are repairable without losing footage.

FIRST THING WE CHECK

The power supply, then whether the drive spins up.

RECORDER · 03 / OVERWRITES TOO FAST

Overwrites too fast

You only see a few days of footage when you expected weeks. The drive is too small, retention is set low, or motion recording is capturing too much.

FIRST THING WE CHECK

Retention, motion settings and drive size against your camera count.

RECORDER · 04 / DRIVE ERRORS

Drive errors

A multi-drive recorder shows one or two drives as failed or degraded. A clean swap on most systems, with footage usually preserved.

FIRST THING WE CHECK

The health of each drive bay, then RAID status.

RECORDER · 05 / REBOOTS ON ITS OWN

Reboots on its own

The system comes up, works for minutes or hours, then restarts. A weak power supply, overheating or unstable firmware.

FIRST THING WE CHECK

System logs, fan and temperature, then the power supply.

RECORDER · 06 / NEED OLD FOOTAGE

Need old footage

The recorder failed and you need what it recorded before, for insurance, a legal matter or an incident. We pull the drive, read it in the lab and recover what is there.

FIRST THING WE CHECK

Stop powering it on. We pull the drive and read it in the lab.

What causes recorder failures 05

The five common culprits, in the order we check them.

DVRs and NVRs fail for a short list of reasons. We work through them in this order.

Hard drive failure

The most common cause. Surveillance drives run under constant write load and fail over time. It shows up as missing footage, write errors, or a recorder that will not boot. A clean swap in most cases, with footage recovery possible when the drive is still readable.

Drive

Power supply failure

The internal power supply has died or is degrading. It causes random reboots, boot failures or complete death. Replaceable with a matched part, with drives and footage preserved.

Power

Firmware corruption

A firmware update went bad, or the recorder runs a version that cloud or app services no longer accept. Reflash with the correct firmware. Common on recorders untouched for years.

Firmware

Overheating

A failed fan, dust buildup, or a hot closet with no ventilation causes thermal shutdowns and shortens component life. Clean, replace the fan, and relocate where possible.

Cooling

Configuration drift

Record schedules, motion thresholds or retention settings were changed, on purpose or by accident, and the recorder is working as told, not as expected. We audit the settings and restore them.

Settings

After an incident

The recorder died. Is the footage gone?

Often not. Most DVR and NVR failures are the processor or power supply, not the drive. We pull the drive, read it in a lab setup, and recover the recordings where the file system is intact.

Do not power-cycle it repeatedlyEvery reboot can overwrite older footage on some recorders.

Note the time window you needThe date and time of the incident speeds up recovery.

Not every case is recoverableBut most are. We tell you honestly before any work starts.

Any brand, even if we did not install it

You do not need the original installer.

Most recorder calls are on systems from installers who are no longer around, with no admin password or paperwork. We identify the recorder, recover access, and repair or replace it.

The recorder brands we service

DVRs, NVRs and VMS appliances across the brands common in NYC commercial and residential buildings. Plus unbranded or rebadged recorders from installers who sourced white-label gear.

The storage and drive side

Recorder failures are often drive failures in disguise. We stock surveillance-grade drives in common sizes and swap them in-visit for most recorders. Footage recovery is handled separately in the lab.

Repair or replace

Recorders are usually worth repairing.

When we repair

A failed hard drive or power supply in a working recorder is almost always a repair, not a replacement. We swap the part, recover the settings, and the system is back online in the same visit in most cases.

When we recommend replacing

The recorder is a dead model with no firmware updates or parts, it cannot talk to modern cameras or VMS platforms, or you were already planning to move from analog to IP and the money is better spent there. Honest math either way.

The repair visit 04

How a recorder call goes.

Four steps, and we test the full record path before we leave.

Phone triage

No footage, will not boot, failing drives or footage recovery. Five minutes on the phone tells us what parts to bring.

On-site diagnostic

Boot, drive status, record schedule, firmware version and system logs. The first 15 minutes identifies the failure.

Fix, order or lab

Common drives, power supplies and standard recorders are same-visit. Specialty parts get a firm order date. Recovery goes to the lab with a quote.

Verify recording

Every camera recording, retention set correctly, playback and remote view working. Written summary for your records.

Frequent questions 06

Recorder not recording FAQ.

My DVR died but we need footage from last week. Can you recover it?

In most cases yes. Recorder failures are often the processor or power supply, not the drive. We pull the drive, read it in the lab with surveillance-aware tools, and recover what is on it. We quote after the first read, so you know what you are paying for and what to expect.

Our footage overwrites much faster than expected. Is the drive dying?

Not necessarily. The usual causes are a drive that is too small for your camera count and resolution, retention set lower than you thought, or motion recording capturing more than it should. We audit the settings first, and replace the drive only if the storage is actually too small.

Can you add a bigger drive to our existing recorder?

Usually yes. Most recorders have a maximum supported drive size and sometimes a maximum number of drives. We check the model, confirm the upgrade is supported, and swap it in. Where it is not, we show you the replacement math.

Our recorder is 10+ years old. Can we still fix it?

It depends on parts. For common older DVRs from Hikvision, Dahua, LTS and their OEM clones, parts are easy to get. For discontinued models we often fit a modern recorder that works with the existing cameras. We tell you honestly which one you have.

Can you recover footage for a legal matter or insurance claim?

Yes, and we document the recovery for chain of custody when it matters. We can produce exported video files with timestamps, hashes and a written recovery report. If you need an expert witness or sworn affidavit, we work with your legal counsel on that separately.

How fast can you come out?

Same-day across NYC when the schedule allows, with priority for recorders down after an incident or at a site with an active security concern. Call 212-347-5400 for the soonest window.
