Account Benefits – Nodac Technology

1. Do you offer free delivery?

Yes. We offer free delivery for orders that meet both of the following conditions:
- The order total is $1,000 USD or more, and
- The delivery address is located in Doral, Florida or nearby areas.

If both conditions are met, delivery is free and fulfilled by our internal logistics team.

2. What if my order does not qualify for free delivery?

If your order doesn’t meet the free delivery requirements, we ship your products via FedEx, our trusted logistics partner. Shipping fees will be calculated at checkout based on destination, weight, and dimensions.

3. Do you ship outside of the United States?

Yes, we do. For shipments to the Caribbean, Central America, South America, or other international destinations, the customer must provide a freight forwarder located in the U.S. (usually in Miami or Doral).
We will deliver the order to the freight forwarder’s address, and from there, your logistics provider handles the international leg of the shipment.

4. How long does shipping take?

- Local deliveries (Doral and nearby): Typically delivered same-day or next business day after order confirmation.
- FedEx (U.S. nationwide): Delivery time depends on the selected FedEx service (Ground, 2-Day, Overnight, etc.).
- To freight forwarders: Delivery is typically done within 1 business day after order processing.

5. Can I track my shipment?

Yes. If your order is shipped via FedEx, a tracking number will be sent to your email as soon as the shipment is processed.
If we deliver it locally, we will notify you by phone or email once it’s out for delivery.

6. Do you offer pick-up at your location?

Yes. You may choose to pick up your order at our warehouse in Doral or Pompano. Just select “Local Pick-Up” at checkout and wait for confirmation that your order is ready.

7. What should I do if my package arrives damaged?

If you receive a package that is damaged, tampered with, or incomplete, please report it immediately to our support team and include pictures. We will investigate and coordinate a replacement or resolution as quickly as possible.

1. What is the IP address to access the camera system?

Answer:
The IP address is usually something like http://192.168.1.100or http://tu-ip-publica:puerto. If you're outside the local network, you'll need the public IP address and port forwarding enabled.

2. What browser should I use to view the cameras?

Answer:
Many older systems require Internet Explorer for ActiveX plugin compatibility. Newer systems work with Chrome, Edge, or Firefox , especially if they use HTML5.

3. What username and password should I use?

Answer:
By default they are usually:

• User: admin

• Password: admin or blank.
  It's recommended to change it for security reasons. If you don't know it, consult your installer or reset your device.

4. Why doesn't the camera image load?

Answer:

• A plugin (ActiveX, VLC, etc.) may need to be installed.

• The browser is not supported

• The port is blocked

• The NVR/DVR or camera is off or off the network

5. What port is used to remotely access the CCTV?

Answer:
The HTTP port is usually 80 , but it can be another port (such as 8080 or 37777). Alternatively, the RTSP (554) or HTTPS (443) port can also be used, depending on the device.

6. What should I do if I forgot the DVR/NVR password?

Answer:

• Some allow you to reset it with a security question or recovery code.

• Others require contacting the manufacturer with the serial number of the equipment.

• Some have a physical reset button.

7. Can I view the cameras from my cell phone?

Answer:
Yes. You must install the app corresponding to the manufacturer (Eg: Hik-Connect, iVMS-4500, XMEye, etc.) and enter the device ID or IP plus the username and password.

8. Is it necessary to have a fixed IP to access from outside?

Answer:
It's not mandatory, but it makes access easier. Alternatively, you can use a DDNS service (e.g., no-ip, DynDNS) that updates your dynamic IP address with a memorable domain.

9. Why does the image look slow or not smooth?

Answer:

• Limited bandwidth

• Bad network connection

• Very high camera resolution

• Non-optimized compression settings

10. What should I do if I see "offline" or "device not found"?

Answer:

• Check that the equipment is turned on

• Check the network and wiring

• Make sure you are using the correct IP

• Check that the port is open on the router

1. How do I access the access control system from the website?

Answer:
You must enter the server or device's IP address into your browser (e.g., http://192.168.1.201or http://miempresa.ddns.net:8080). Use your assigned credentials. If you don't have access, contact your administrator.

2. What do I do if I forgot my username or password?

Answer:
Request a password reset using the PQRS form or contact your company's technical support. For security reasons, some systems require manual verification.

3. Why can't I see the logs or access history?

Answer:
Verify that you have the appropriate permissions. If the error persists, there may be a communication failure with the device or server. Report the issue to support.

PROXIMITY AND BIOMETRIC READERS

4. What is the difference between a proximity reader and a biometric reader?

Answer:

• Proximity: Use RFID cards or tags to validate access.

• Biometric: Uses fingerprint, face, or iris for authentication.
  Both can be combined for greater security.

5. What types of cards are used with proximity readers?

Answer:
It depends on the reader. The most common are:

• 125 kHz (EM/HID) – low frequency cards

• 13.56 MHz (MIFARE / DESFire) – high-security and multifunction cards

6. What should I do if my biometric reader doesn't recognize my fingerprint?

Answer:

• Clean the sensor

• Make sure you place your finger correctly

• Try again with a different finger if it is registered.
  If the problem persists, request a new fingerprint capture.

COMMUNICATION PROTOCOLS

7. What communication protocols do access control systems use?

Answer:
The most common ones include:

• Wiegand (26, 34, 64 bits) – for proximity readers

• RS485 / RS232 – for serial communication between devices

• TCP/IP – for networking

• HTTP/HTTPS – for web management

• ODBC/SQL – for databases

8. Can I integrate readers from another brand into the system?

Answer:
Yes, as long as they use compatible protocols like Wiegand or OSDP . For advanced integration, software and driver compatibility should be verified.

9. What is the difference between Wiegand and OSDP?

Answer:

• Wiegand: This is an older and more limited unidirectional protocol.

• OSDP: Modern, bidirectional, encrypted protocol, ideal for more demanding security systems.

FREQUENCY AND TECHNOLOGY OF THE READERS

10. What do the frequencies 125 kHz and 13.56 MHz mean on readers?

Answer:

• 125 kHz: Low frequency. Compatible with EM/HID cards, which are less secure.

• 13.56 MHz: High frequency. Compatible with MIFARE and DESFire cards, providing greater security and greater capacity.

11. Can I use the same card for multiple access points (cafeteria, printing, etc.)?

Answer:
Yes, if you use 13.56 MHz cards (MIFARE or DESFire), which allow multiple applications on the same chip.

12. Do proximity readers interfere with each other if they are too close?

Answer:
Generally no, but they should be installed at a minimum distance (usually >30 cm) to avoid electromagnetic conflicts.

SUPPORT AND MAINTENANCE

13. How often should I update or perform maintenance on my system?

Answer:
It is recommended:

• Software: Check for updates every 3-6 months.

• Hardware: Cleaning and functional testing every 6 months or depending on environmental conditions.

MONITORING AND CONNECTIVITY

13. Can I receive alerts on my cell phone?

Answer:
Yes, if the system has an IP, GSM, or WiFi module. Alerts arrive via notification, call, or text message, depending on the alarm type.

14. Does the system work without internet?

Answer:
Yes. Alarms can operate locally. However, remote notification requires a cellular network or internet connection.

15. What happens if the power goes out?

Answer:
Alarm panels have an internal backup battery that allows them to operate for several hours after a power outage.

MAINTENANCE AND USE

16. How often should I check the system?

Answer:
We recommend performing functional tests at least every 2-3 months and changing batteries according to the manufacturer's recommendations.

17. Can I install the alarm myself?

Answer:
Yes, if it's a basic wireless kit. For more complex installations or monitored systems, professional installation is recommended.

18. What do I do if the sensor gives false alarms?

Answer:

• Check for moving objects (curtains, pets, etc.)

• Check the sensor sensitivity

• Clean the lens and check for interference
