Troubleshooting Steps for HoistCam Communication, Wireless and Antenna Problems
Last Updated 6 days ago

The following steps should be completed in order to verify proper power, communication and antenna configuration. These steps are performed when the red pair light inside of the HoistCam and on the VRB (Video Receiver Box) are not solid red.

  1. Power confirmation:
    1. HoistCam Camera - greater than 12.5VDC (approximately 50%)
    2. HoistCam VRB (Video Receiver Box) - powered on and is receiving 12VDC power
  2. VRB (Video Receiver Box):
    1. VRB Connector - Make sure the central pin is not recessed (almost even with the end of the bulkhead connector), clean, not corroded and tight to the enclosure.
    2. Antenna Cable - Make sure the central pin is not recessed (almost even with the end of the connector), clean, not corroded and tight to cable.
    3. Antenna Cable - Make sure the antenna cable is not ran along a power cable. EMI can interfere with the antenna cable
    4. Dielectric grease (looks like clear glue) is inside of every end of the connectors.
  3. Antenna Side:
    1. Any right angle or T-Connectors - Make sure the central pins are not recessed (almost even with the end of the connector), clean, not corroded and tight to adapter.
    2. Antenna Cable - Make sure the central pin is not recessed (almost even with the end of the connector), clean, not corroded and tight to cable.
    3. Antenna - Make sure the central pins are not recessed (almost even with the end of the connector), clean and not corroded.
    4. Dielectric grease (looks like clear glue) is inside of every end of the connectors.
    5. Make sure the receiving antenna is not near an electrical box or conduit. Electrical boxes can cause EMI (electromagnetic interference).
    6. Make sure the receiving antenna is not behind glass, especially polarized glass.
  4. Other Variables:
    1. Verify that there are no other wireless cameras in the area; Try turning them off for testing purposes

After verifying all of the connections are good, step through the re-pairing sequence if the HoistCam needs to be paired to the VRB again.

Advanced Troubleshooting:

  1. If a spectrum analyzer is available, the frequency can be measured from 2.410Mhz to 2490Mhz across the entire spectrum with a desired maximum transmit greater than -35dbm.
    1. -30dbm to -28dbm is observed in ideal conditions such as in a Faraday chamber and the HoistCam lid open.
    2. A lower dbm indicates a stronger signal (-30dbm is more powerful than -40dbm)
