I noticed that on a rainy night just after midnight to a few minutes after 6:00 am that 3 of the 6 cameras on the CCTV system stopped showing and recording however they work fine in the daylight. One of the functioning ones was grainy and showing intermittently. I have identified the offending camera. When I turn on the lights that camera along with the others are functioning. When I disconnected that camera, the others are working fine with night vision. I am wondering why the issue with the problem camera is affecting the other cameras on the network. Does anyone have any idea what could have caused this problem?

Thank you for your response

I am using a 12V-13.8VDC Output Security Camera Power Adapter to power 2 of my cameras Will using the power supply set at 13.8VDC cause any damage to the cameras or DVR? The cameras are located about 10 metres from the DVR

.I tried using this 2.5 amp. power adapter splitter to power both cameras. However, I noticed that I am getting ground loop problems. When I used two separate power supplies the ground loop problems stopped. Are these power splitter power adapters any good? On another note, I noticed is that the guy who installed the other 5 cameras used an “EPCOM DC ADAPTOR MODEL PS120DC4C” power supply 5 AMPS Although the adapter says 4 channels, he doubled the connection on one terminal to accommodate two cameras on that single terminal. Is this normal?

Thank you for your response.

Thank you

When installing a camera, is it necessary to use all 3 pairs of remain wires in cat5e cable for the power supply as shown in this diagram?

Is it necessary to use all 3 pairs of remain wires in cat5e cable for the power supply as shown in this diagram? The cameras are just a few metres from the DVR and the cat5e cable is about 12 to 15 metres long

Thank you for your response I want to add 2 of these cameras to my system.

Does anyone know what amperage powers supply is required to power two of these cameras? The manual is silent on this issue. https://www.hikvision.com/en/Products/Analog-Camera/Turbo-HD-Camera/5-Mega-Pixels/Outdoor-Dome/DS-2CE56H0T-ITMF

Thank you for your response. Forgive my ignorance, I am a novice to CCTV but is the HDView brand Camera any good?

My current CCTV system is a Hikvision I just wanted to add a camera

I am looking for a 5mp Analog varifocal Hikvision turret or dome camera. An Amazon merchant emailed me saying he has a Hikvision OEM varifocal Camera. He said “The camera is manufactured by Hikvision however, it does not have logo or brand and the box is plain brown box.” What’s the difference between the Branded Hikvision and the OEM version? And would it be compatible with the Hikvision DVR 7208 that I am currently using?

Thank you for your advice. I don’t think that the remaining areas would need plate recognition although face detection may be an advantage.

Thank you very much I checked the frames per second on the DVR and the manual and you are right. I am using the Hikvision Turbo 7208 DVR and it adjust the frame per second according to the megapixel of the camera, in this case for the 5mp camera the maximum frame per second is 12. At 8mp it would be 8 frames per second, for 3mp it would be 18 frames per second and so on.
