AXIS P1355 Camera I/O + relay to turn on light/garage door

AI Thread Summary
The discussion focuses on using the AXIS P1355 camera to control a green traffic light and a garage door based on license plate recognition. The user seeks guidance on selecting the appropriate relay and diode for connecting the camera's outputs to a 220V traffic light and garage door system. Key questions include whether the camera's outputs can be connected directly to the garage door inputs, and if both devices can share the same outputs without additional circuitry. Suggestions include using a remote control for the garage door, potentially simplifying the setup by connecting it directly to the camera's output. The user is looking for ready-made solutions but has found limited options.

here is the manual http://www.axis.com/en/files/manuals/um_p1355_49956_en_1303.pdf

see page 61

Notes: i have seen this thread https://www.physicsforums.com/threads/axis-camera-with-i-o-and-relay-to-turn-on-lights.538043/ but this camera is a bit different i think as it has digital inputs and outputs and different voltagei need to use this camera in a parking lot to turn on a green traffic light and at the same time open a garage door/barrier when camera recognizes the correct license plates (via embedded separate application installed in camera which will trigger the i/o) as output from the camera (i won't use inputs at all in this application only output alarm of the camera)

Im trying to figure out which relay and diode should i use and how to connect them to the camera but i can't figure it out and documentation of the camera isn't helping at all, i searched ebay and i can't find a proper relay that will do the job or at least i think, any ideas ? The traffic light is 220v (x1 60w-100w normal light bulb that will turn on when barrier/garage door opens from the camera and off when it closes) I would prefer a relay with built in diode for simplicity if available

My guess is pins 4 and 2 should be connected to 220v relay with 3.3v drive and the diode head arrow should point to pin 2 or pin 4 ? the plus goes to pin 2 from relay coil ?

This is the first question the second question is when i connect the output to the garage door inputs (ssee attached pic) can i connect it directly from the camera or does it need a diode and relay again ? I think garage door has its own relay right ? so i should put diode again in parallel so it won't burn the camera out ?

Third question can i connect both the traffic light and the garage door inputs to the same outputs of the camera directly or do i need some circuit in between that needs to be purchased separately?

If there are any ready made solutions for this please let me know as i searched google without success

(this guy is out of the question http://www.ibou.fr/cameras/cameras.html too expensive and not responsive to emails)

thanks a lot for any help in advance

p.s. someone suggested i could do this easier (part 2 of the question) by using directly the remote control of the door and wiring the camera via the relay to the remote directly which works with a small 12v battery. In a few words glue the button of the remote permanently down and the camera via the relay will provide 12v momentarily via relay open to the remote which will act like a button was pushed and door will open.any thoughts ? cheers

p.s.2 i got another remote which uses exacty 3.3 v battery like the camera alarm output's could in this case be wired directly from camera to remote without relays and diodes or it won't work ?

thanks

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
