Spasiba 0 Posted February 9, 2019 Purchased a AHD Security Camera off Aliexpress not sure what the issue is with the camera but link to the camera is below.. https://www.aliexpress.com/item/2-0MP-1080P-HD-AHD-TVI-CVI-1200TVL-CCTV-Security-CS-Box-Color-Mini-Camera-OSD/32882234708.html Problem I am having is that their is no picture showing when it's plugged in and power is on, I removed the cap that blacks the sensor and I can clearly see the chip in the back. Red LED on the back of the camera comes on, have the camera connected to a BNC plug that runs to a dash cam monitor no picture is showing on the monitor also tried using a USB capture card that connects to a computer still no image all of the stuff I am using works fine with other BNC security camera's. I am not sure if their is a bad board I opened the camera enclosure housing every thing is connected wires look fine but no video shows up I should at least see a over exposed video but nothing. Was told by the seller on Aliexpress that I need a AHD DVR to test that camera would that really be true that the camera would only work with a DVR and can't be tested without a AHD DVR I am a bit confused why that camera wouldn't be able to display a picture without a AHD Dvr but all my other BNC camera's work fine without a DVR. They all use a 12v 1a AD/DC adapter and have a BNC plug and will work fine with the monitor or USB capture card connected as far as I know nothing is different.

Hi. Yes you need a dvr .....your camera is a 4 in 1 and a dvr would detect the format I.e cvi tvi AHD or analog.. you can't use a HD camera direct onto a monitor you can with old standard analog cameras Share this post Link to post Share on other sites

The button on the back of that camera has a set button pressing on it doesn't bring up a menu, took the cap off the front of the camera, their is no image going thru the camera. Tried using a BNC to USB capture card nothing tried connecting it to a small monitor no image shows on it either. And I am using the CVBS cable both cables have a yellow plug one for male and one for female. It's freaking silly if the camera can only be used by a DVR I have never heard of a security camera that requires a DVR to work. The seller on Aliexpress claims you need a DVR as well.

cctvman1379 2 Posted February 17, 2019 You'll need a DVR to change the mode but once in the cvbs mode it'll not need the DVR could you get take it to someone who's got a DVR with HD input and change the setting through their DVR Share this post Link to post Share on other sites
tomcctv 190 Posted February 17, 2019 Hi. On the spec it warns that default is AHD so putting it on a AHD dvr setting it to analog .....once powered down it will go back to AHD Share this post Link to post Share on other sites
cctvman1379 2 Posted February 17, 2019 Once it's set to a particular mode even. If. Power is. Lost it should stay in that mode Share this post Link to post Share on other sites
Spasiba 0 Posted February 19, 2019 Eh gonna have to give a call around town for a security camera shop and see if I can get them to do that, will double check the out come of the camera by disconnecting it and hooking it up to a small monitor and seeing if it stays. I mean here's the funny thing I right now have a HD UTC Controller I've set it to both AHD and CBVS and it didn't pop up a menu with the UTC controller which is why I find it a bit funny do I really need to do this connected to a DVR or should the UTC Controller enable me to switch. I guess I might have obviously left that part out about me having a UTC controller. Share this post Link to post Share on other sites
tomcctv 190 Posted February 19, 2019 hi itv controller still will not work as the output is still AHD so won’t work on monitor you can go to cctv shops but like spec says it is a default AHD .... power down it will go back to AHD also so did you buy the camera for it’s spec ? 2mp Share this post Link to post Share on other sites

It looked very similar to the Revolution Imager camera that sells for $300 bundled, was trying to save a bit of money trying to see if I could just find the same camera or one like it. Cause I don't really need the bundled kit. At this rate I've almost spent enough money trying camera's like this that either don't have OSD with UTC feature. I believe a few other people possible came here asking about camera's for Video Astronomy. Share this post Link to post Share on other sites
