I changed my password or forgot or lost it
Most people change the password on their devices whether they be a spy gadget or a CCTV systems.
This is the correct thing to do to ensure privacy, however you should be aware that in many cases the device will no longer be repairable.
For the spy gadget end you will need to repurchase the item or do you very best to try and remember what you changed it to.
For CCTV system DVRs and NVRs, it is possible sometimes to get the manufacturer to supply a temporary access code, however many times this will involve sending your recorder to OzSpy Head Office for reset and charges may apply.
Remember, electronic security is designed to be safe, so you are unlikely to ever get back in in many devices.
