Observant V1 Camera
The V1 is a low-power, ruggedised, color, still-image camera. It communicates to (and is powered by) the C3 field unit via a 4-way electrical connection.
The V1 is a standard, Modbus, serial communications device and is supplied with cables terminating in Observant's standard, 4-way, device connector. For wiring details, see Figure 1, below.
- The standard C3 device cable (DTC) is 19' 8" (6 m) in length, this may be shortened if desired by re-wiring the terminal block end.
- If a longer cable run is needed the 32' 9" (10 m), device extension cable (DCE) can be used.
- Either cable will connect to the V1's cable as shown in Figure 1.
- Be sure to mate the C3 and V1 cables carefully and secure with the knurled ring on the V1 cable
- Note: either RS485 port on the C3 may be used.
- Be aware of the of the V1 camera's field of view when selecting a mounting location. See Figure 2, below.
- The V1 can mount to the same pole as the C3 using the provided pole-mount bracket, as shown in Figure 3.
- Either high-quality, flexible conduit or standard, rigid, electrical conduit can be used to protect the cabling.
- Alternatively, if the elevation allows, the V1 can be mounted directly into the 32 mm, bottom-entry hole of the C3—as seen in Figure 4.
- Be sure to install the V1 body with its vent hole oriented downward; otherwise, your image will appear upside down.
- Ensure that the vertical adjustment bolt is fully tightened only after you are satisfied with the position of the camera.
- Note: the 4-way device connector on the end of the C3 device cable can be threaded through standard 1" (25 mm) electrical conduit.
