I have a Swann the power light is flashing green and likewise the power light on the monitor. i had a computer firm check the hdd and it appears to be working have also tried another monitor .

A flashing green light on a Swann 960H Pro Series security camera system can indicate a few different things, depending on the specific model and configuration of your system. Some possible causes of a flashing green light include:

1. The camera is in setup mode: When a camera is first powered on, it may flash a green light to indicate that it is in setup mode and ready to be configured.
2. The camera is in standby mode: When the camera is not actively recording, it may flash a green light to indicate that it is in standby mode and ready to start recording.
3. The camera is recording: Some models of the Swann 960H Pro Series security camera system have a green light that flashes when the camera is recording.
4. The camera is low on power: Some models of the Swann 960H Pro Series security camera system have a green light that flashes when the camera is low on power.
5. The camera is malfunctioning : Some models of the Swann 960H Pro Series security camera system have a green light that flashes when the camera is malfunctioning.

hdd might be full or bad,, check is overwrite parameters are set..

Here's some tricks I would try. Something here, might help...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your monitor on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
Good luck.

Yes it should flash the red led, that means that the system is recording at that specific moment....I would worry if there is motion in the front of the cameras and the red light wouldn't flash.

1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.

My DVR box is powered up but, i get no picture and the HDD red light is flashinG

When you switch on both Poota and Monitor, is there visual startup flashes or startup information showing on screen.

Make sure the monitor connect to rear of poota is located and firmly in place and properly screwed in?

That usually means that the connection between the PC and the monitor has been interupted- check that the cable (probably has blue ends) between the two is firmly connected, and power it back up. If that doesn't work, you have one of three problems; a broken VGA cable, a broken monitor, or a broken video card. Finding out which- you'll actually need someone tech-savvy there to help you figure that out. Try plugging the monitor into a different computer. If that fails, use a different VGA cable (cables are pretty cheap at monoprice.com), and if that fails, it's your video card.
