Terminal Wire Connections
The terminal block wire connections are described in Table 1.
The terminal block can be used to connect the MemoCam power sources as follows:
Single Power Source – The MemoCam unit is powered by a 12VDC, 500mA power supply that feeds both the PIR and the video circuits. The MemoCam DVR is powered by a 12 VDC, 400mA power supply.
Dual Power Source – The MemoCam unit can be connected to a normal power supply and a backup power source. In this configuration, when the ordinary power supply is not available, the backup battery powers only the PIR, and thus can still activate an alarm. The MemoCam cannot record images in backup power mode.
The jumper is used as follows:
Installed (Default) – The MemoCam unit is powered by a single DC power supply connected between terminals 1 and 2.
Not Installed – In this mode, the MemoCam unit can be connected to a backup power supply such as UPS or a battery from an alarm panel, in addition to the main power supply. The backup power supply is connected between terminals 1 and 2, feeding the PIR, while the video circuits can be fed by an ordinary power supply via terminals 1 and 3.
