I forgot my password to my Defender Security DVR, online support says they will only respond by email in a few buisness days and only if so info matches their system, and I have no clue as to the date I purchased this! Is there a way to hard reset this or is there an override password?

Please think twice and realize people can not help you when they do NOT know what the particular device are you talking about!
What the particular model of the Defender DVR device you are talking about?

Here is an article about hardcoded support passwords in some DVR's including some Defender DVR's (a brand of Circus World Displays), which (may be!) you can use to access your device.
Read carefully and look if this info related to your case.
Search with Google info on your particular model, it's internals and access methods. Most of advanced network DVR's contain Linux-based firmware, so there are good chances for hackers to explore firmware internals and find useful things.

In the modern world any devices may be produced by any manufacturers and sold under any brands. Thus, internal architecture of the particular device and its real properties is highly depend not only on the particular device model, but even its hardware revision. E.g. many network devices having the same brand, the same model, the same casing, but JUST ONE different letter in the revision string could have been made by absolutely different real manufacturers and have absolutely different boards, CPU, hardware configuration and firmware.
It's a real fraudlent world and stupld 'money making Matrix system', we built. Forget about brands. The only countermeasure we have is our wide knowledge and accuracy.

Get the 12 digit alpha numeric mac address off of main board and call your tech support. They should have, as I do, a keygen for the master password for that main board. Any reputable dealer will have the MacCov program from Rifatron.

    How to reset my pass word on my Samsung Security Video System SDH-B74041

    For nearly all Samsung Security DVRs, the default password is 4321. If it hasn't been changed since setup, then you can just use that to access the DVR. The default password is included in the reset procedures for completeness. If you have changed your password or access code for your Samsung Security DVR since it was setup, or if you changed it during the initial setup, use that password in place of the default password. The password will be the latest password that was set on the DVR. If no password has ever been set, then it will be the default.
    Samsung Security DVR Reset Procedure #1
    1. Reset the unit to factory by pressing both [MODE] and [PTZ] button for 5 seconds
    2. Then enter the 4321.
    Samsung Security DVR Reset Procedure #2
    1. Reset the unit to factory by pressing both [MODE] and [CH2] button for 5 seconds
    2. Then enter the 4321.
    Samsung Security DVR Reset Procedure #3 This reset will work on Android based DVRs only. All steps are performed on the device itself.
    1. Turn the device Off
      Wait 2 minutes
      Press and hold the following buttons
      • POWER,
      • HOME
      • VOLUME UP
    2. The unit should power on. Once it does, you can release power.
    3. Use the volume UP and Down buttons to select "Wipe/Factory Reset" from the recovery menu.
    4. Activate the reset using the HOME button.
      When the DVR goes through it's setup again, it will be at factory defaults. The password will be 4321.
    Samsung Security DVR Reset Procedure #4 This reset will work on SDR models. It may also work on other models.
    1. With just the cameras showing, press the following in quick succession using the remote:
      • Freeze
      • Alarm
      • Freeze
      • Alarm
      • Freeze
      • Menu
      • Enter
    2. Make sure you press them quickly, one after the other. If it doesn't work the first time, try doing it several times. It can take many tries to get the timing right. If/when it works, you should get a screen that gives you the option to reset.
    Samsung Security DVR Reset Procedure #5 This reset will work on SDR models where procedure #4 failed. It may also work on other models.
    1. Press the DVR Button to place the system in DVR Mode
    2. Press:
      • Freeze
      • View
      • Return
    As with Procedure #4, you may need to press Freeze, View, and Return in in quick succession a few times to get it to work. The timing can be tricky.
    These reset procedures cover many Samsung Security DVRs, but not all. I will add reset procedures to this article as they become available to me. By design, Security DVRs are made to be secure, and not all of them can be reset by the consumer. If you have an urgent need related to your Samsung Security DVR, you should contact Samsung directly at their support page Samsung Support, or by calling: 877-349-3149. For less urgent matters, you can email them directly at Email Samsung Support. Support is available 7 days a week, 9:00 am - 9:00 pm EST.

    The security camera on my phone quit working. need to fix it please?

    Hello there,
    You need to first save the settings info by jotting down all addresses and passwords. Next, uninstall the software and restart your phone. Re-install the software, in so doing look for an updated version if possible. If this does not work, then open your DVR software settings and check your Mobile settings. Make sure that the user name and password still stands. This includes your server port. That should fix it.
