Read this before you do anything else
Do not power it on, and take it off charge. Corrosion is the clock.
Current through wet circuitry drives corrosion and shorts components that would otherwise have survived. The damage continues for as long as the device is powered and for as long as it stays wet, which means the two things that matter are cutting the power and getting it looked at quickly. Drying it out on a shelf is not neutral: corrosion progresses while it sits, and the residue left behind by evaporating water, especially salt water or anything sugary, keeps attacking the board after the moisture has gone.
Emergency
Water damaged CCTV recorder
If your CCTV recorder has got wet, the most useful thing on this page is above this paragraph, and it is free. What follows is what the fault usually turns out to be, how recoverable this class of failure is, and what it would cost, including the cases we would tell you to take elsewhere.
What this usually turns out to be
Recorders live in ceiling spaces, roof cavities and outbuildings, which is precisely where roof leaks and burst pipes end up, so water damage to a DVR is usually a slow drip from above onto a unit that has carried on recording throughout. That matters more than the water: the unit has often been running wet for days, corroding under power, while also continuing to loop over the footage you need. The drive inside is sealed and its platters are usually fine.
Recorders write in a manufacturer's own format and loop over the oldest footage continuously. The clock on a CCTV job is retention, not hardware.
Corrosion on the circuit board
Progressive, and it continues while the device sits waiting. This is why a water job is genuinely time-sensitive in a way most other failures are not.
Short circuit from powering it on wet
Often the actual killer rather than the water itself. Components survive immersion and then fail on power-up.
Sealed platters, untouchedbetter news
The platter chamber is sealed at the factory and vented only through a filter. Water frequently reaches the exterior and the circuit board and stops there, leaving the recorded surface completely intact.
What to check first on a CCTV recorder
- Cut power to the unit at the wall.
- Open it and look at where the water landed, since a drip from above frequently hits the power supply and misses the drive entirely.
- Work out the retention window and the incident date, because a unit that kept recording for a week may have already overwritten what you needed.
What not to do
Do not power it up to check whether the footage is still there. If the board is wet you risk the unit, and if it starts successfully it resumes recording and continues overwriting. Do not accept any prompt to format or prepare the disk afterwards.
Try this before you pay anyone
There is one thing to do, and several popular things not to
- Take it off power. If it is a phone, take it off the charger and do not press the power button to check.
- If it is still wet, keep it that way rather than letting it dry with residue in place, because a device that dries with contamination on the board corrodes underneath it. Get it to someone quickly instead.
- Note what the liquid was. Salt water, pool water, and anything sugary are substantially more aggressive than clean tap water, and it changes how the board has to be treated.
Skip the rice. It cannot reach the inside of a sealed device, it does nothing for corrosion already underway, and it costs the days that decide a water job. A hair dryer drives moisture further in and can lift components. Neither of these is a small mistake. They are the two that most often turn a recoverable water job into an unrecoverable one.
How recoverable this is
Better than most people expect, and it degrades with every day of delay. On hard drives the platter chamber is sealed, so the recorded surface is often perfectly intact and the work is on everything around it. On phones and SSDs the memory package frequently survives a board that does not. What consistently makes the difference is elapsed time and whether it was powered on while wet.
What moves it, for your device specifically:
- How long since it got wet, and whether it has been powered since
- What the liquid was: salt, pool and sugary liquids are far more aggressive
- Whether corrosion has reached the storage itself or is confined to the surrounding board
- Whether the sealed enclosure kept the liquid out of the head and platter chamber
We will not give you a percentage for your device, and you should be wary of anyone who does. Nobody can know what is recoverable until the media has been imaged and read. What is above describes this class of failure; your drive gets its own answer after an assessment, in writing, at no cost.
What it costs
Quoted after assessment
CCTV, NVR and DVR footage
Proprietary recorder formats parsed directly from the disk. Priced on recorder type, number of disks and the time window needed.
Nothing is charged until you have seen a fixed quote for your actual device and agreed to it, and the assessment that produces it is free.
