Question: what is the right power source for this camera? and what type of video cable?
Document: Most home type CCTV cameras require somewhere between 200mA and up to 800mA for a zoom with a lot of "bulbs".I'm now using a 2000mA power supply, and using a 16 AWG cable (lamp cord or speaker cable) to power the camera mounted 40 feet away from the power supply.
I studied on this camera and read the reviews to make my mind up. The day vision is great, but the night vision doesn't work, just a xray ghostly terrible picture.I will have to return it. Hate to lose the camera.I solved the problem, changed the video cable to RG 59 and put it on its own 2amp power supply. The night vision is over 300ft and the night is as good as the day.Great customer service.
First time using a bullet camera of this type. LED's threw me for a loop.The picture is very sharp and colors are great. Sourcing the 2 Amps for the camera was a bit of a challenge as I purchased 4 of these and finding a Power distribution box that will power these along with the other 12 Cameras @ 1Amp was an issue, Went with 2 Distribution Box's. If only I could find these with vari-focal I would be a very happy installer!
You could also use a CAT 6 Ethernet cable, using three wire pairs, for 2800 mA capacity. Otherwise, you could either mount a 2000mA power supply next to the camera, or use typical 16 AWG power cord, with a balun connector at the camera end, like I did. However you do it, this is still a great night time camera, but you'll need to be somewhat handy with wiring to properly power the camera.
I had 50' pre-made cables, which work perfectly with all of my other CCTV IR cameras, but they could not supply enough current to operate the 4 large IR lamps that these cameras use. I am guessing that this model draws 600-800 milliamps or more, but I don't have the equipment to measure it. The camera only worked at night when I used a 2' long cable and a 2 amp power supply (2000 milliamps)--not suitable for most CCTV installations.
Last night I replaced what appears to be wimpy 24 AWG power cable on one camera with a shorter run of 18 AWG power cable and the night vision works flawlessly now. So spare yourself the wasted money of purchasing a cheap BNC and power cable combo and buy either a higher quality combo with at least 18 AWG power cable or purchase them separately. I will update once I replace the power cable to the second camera.
I bought these to go with one I purchased earlier this year. They are very clear day and night. Like most people say, these cameras need the full power for the IR. I run a poe from DVR to camera and use a 2a power supply. My distance is about 70ft and have had no problems. These have been installed so all 3 are up and running. This quality of video, night vision, price point and PTZ would be everthing I need for my shop security.
I have been using this camera for about a month. As others have said you need to make sure you are not using thin audio/video combo wire for the power as well. I have a separate 16 gauge outdoor rated extension cord for power. Before I did this, the night time picture was worthless. The camera needs to be able to draw enough power for the IR. After I made this switch the camera works flawlessly. Good pictures day and night for this price.
The array type ir give the best spread of illumination. Customer thinks the camera is great also. I have bought more like this cam.
The Loftek NAJA-6H is the best BNC &#34;sub HD&#34; security camera I have found. At 600 TVL, it has a good picture duringdaylight, but after dark is where it really shines, both figuratively and in reality. The four infrared beams lights upthe area almost as good a daytime. I am very impressed at its performance for its price. If you are using the oldcoax type of connection, this is the best camera for the $$ I have found.
Answer: Coax cable with 12v power supply
