    Again, you must match the DVR and PTZ address and protocol.

     

    Follow this steps:

     

    Let's setup your Pelco PTZ to Pelco D, 2400 baud rate, address 1

     

    1. DIP switch #3 must be on all OFF position. (that is Pelco D at 2400 baud rate)

    2. DIP switch #1, turn ON switch #1( that is address #1)

    3. Install the PTZ and make sure you have the right settings by looking at the configuration screen.

     

    D address: 1

    P address: 2

    Comm: 2400, N, 8, 1

    Configure done

     

    Now setup your DVR by matching the above configurations.

     

    I want you to move the BNC wire of the PTZ to DVR input #1

     

    Under PTZ device of the DVR menu make sure it is on channel #1

     

    Under RS485 device of the DVR menu select Pelco D or (Pelco Spectra if available)

     

    Make sure your data wire RX+ and RX - polarity are correct.

    You need a 24VAC/ 50VA power supply to power up Pelco PTZ. If your housing is environmental and has fan and heater built into it you need at least 70VA at 24VAC. (do not use 24VAC plug in transformer that is 20VA)

     

    I am using Pelco WCS1-4 to power up my Pelco Spectra III and IV.

     

    Good Luck!

    The RJ45 on the back of your DVR is NOT for PTZ connection. It is for network connection only. Connect your PTZ data to RS485(A & B). Yes you can connect 2 or more PTZ's to your DVR.

     

    Give us more information about the model of your PTZ's. It maybe a IP PTZ's and it's not compatible with your analog DVR.

     

    Good Luck!

    According to your PTZ camera power specs, your camera can tolerate +10% of the input voltage (DC12V+10% 50W) that's around 1.2 volts. AT 100 feet in length using 18 guage wires at 14.2 VDC your losses is around 23% that's 2.64 volts (14.2-2.64=11.65 volts). You are very close to 12 volts but you forgot to mention the amps/wattage of the power supply you're using (14.2 VDC). Your PTZ consumption is 50 watts.

     

    Good Luck!

    I would suggest to use a 24VAC 50VA power supply for the cameras that is 1000 and 600 feet away and use a AC to DC Power Converter (24VAC to 12VDC Regulator). The converter input is from 20-36 volts AC so even if your AC drop to 20 volts the regulator maintain its output to 12VDC. I recommend you use 14-16 power wire. I have tried this using 18/2 and I have no problems at all.

     

    Now let's go to your video signal. A good quality RG-59 can go as far as 1000 feet but that is no longer in compliant. Some cameras can tolerate this distance and have no problem at all. If you experience a signal drops and the image is wavy I suggest you use a ACTIVE video baluns by running CAT5 or CAT6 cable. Remember video baluns works on twisted pair wires or UTP.

    Yes it is a voltage drop issue. If I were you I will use a 24VAC/50VA power supply to each PTZ camera. If your PTZ camera aren't dual voltage (12VDC/24VAC) then

    I will use AC to DC Power Converter (24VAC to 12VDC Regulator) at the end of the camera. They are rated at 2 amps at 12VDC some are more. I am assuming your power wire is at least #18 or better. Even if your AC drop to 20 volts you're still getting 12VDC all the time.

     

    Good Luck!
