4 years ago I have other question about config in the rposConfig.json "PTZOutputURL": "127.0.0.1:9999", What does this line mean?
RPOS will receive PTZ commands in ONVIF Format. It can convert the PTZ Command into older 'serial data' PTZ format (sometimes called RS485 data). The serial data formats supported are Pelco-D, Pelco-P and Sony VISCA. RPOS then has to send the Serial Data (eg Peldo-D serial data) somewhere. It can send it to a USB COM Port or it can send it to a Socket. In this case 127.0.0.1:9999 is sending the Pelco-D serial data to a Socket. There would be some other server listening on Port 9999 that knows what to do with Pelco-D serial data.
It does not send an ONVIF PTZ command on to the URL. That could be added. But right now it is just RS485 Serial Data for Analogue CCTV cameras.
I checked the operation of rpos with the milesight VMS lite. The command Focus Far is worked normally. But Focus Near does not work. It issues comes because in the PTZDriver.js has :
else if (command === 'focus') { if (_this.pelcod) { if (data.value < 0) _this.pelcod.focusNear(true); else if (data.value > 0) _this.pelcod.focusFar(true); else { _this.pelcod.focusNear(false); _this.pelcod.focusFar(false); } _this.pelcod.send(); } }If I send focusNear command then data.value === 0 . I changed if (data.value < 0) to if (data.value <= 0).I have other question about config in the rposConfig.json
"PTZOutputURL": "127.0.0.1:9999",What does this line mean? Can I use Raspbery pi to relay onvif commands to another onvif camera? For example: raspberry has the address 192.168.1.2. There is a camera on the local network with the address 192.168.1.3. My videoserver sends the zoom command to the address 192.168.1.2. Raspberry recieve this command, sends it to the serial port and sends the onvif command to the camera via TCP. The camera also responds to this command.
