Troubleshooting Camera On/Off or No Image Scenarios
The following steps may help to isolate and eliminate camera connection issues.

Note: Proper GRIDSMART installation requires testing all equipment prior to installation to eliminate any potential issues that may occur while pulling of the cable from the cabinet to the camera location.

Intermittent Camera Image
Grounding of Shielded Cat5e

Intermittent Camera or image drop may be caused by electromagnetic interference (EMI), a cable distance over 100m, or a poor connection or kink in the Cat5e cable. To reduce the effect of EMI, proper GRIDSMART installation requires using a shielded cable with a grounded drain wire. The drain wire should be grounded to the Junction Box or EPM ground lug.

  1. Verify the installed cable is a Shielded, gel-filled, burial grade Cat5e. 
  2. Ensure the drain wire is grounded to either the SMCH or SMC2 ground lug or, if using the SMC, to the EPM ground lug. 
  3. Check the distance from the cabinet to the camera. If the cable distance exceeds 100m an Ethernet Repeater is required. 
  4. Check the terminal block connections in the SMCH & SMC2 Junction Box and all RJ45 connectors.

No Camera Image
GS2 Ground

No image may be caused by – faulty RJ45 connection, GS grounding issue, bad EPM or Junction Box, damaged Cat5e cable, or other grounding/power issues in the intersection.

  1. GS2 Only – see TSB above. If applicable, apply the grounding kit fix. 
  2. Review steps 1-4 under Intermittent Camera Image. 
  3. Using the GRIDSMART Client, verify the 48v power in the Diagnostic window. 
  4. Check cable integrity using a quality cable tester 
  5. Bypass the EPM and plug the camera directly into the GRIDSMART Processor 
  6. If available, connect another camera to the processor and verify the camera image. 
  7. Bypass the Junction Box using an RJ45 Coupler 
  8. Remove the installed camera and plug it directly into the processor.
