... that is until I received these.I worked Retail Security for over 12 years, and even the most basic CCTV Cameras have been color for the last few decades. I can't begin to comprehend why these are even available to purchase these days. Decent price? Sure. Of any use if someone kicks in your door? Nope.Let's role play, shall we? Police: What color shirt was the suspect wearing? You: I don't know. Police: What color was the vehicle they got in to? You: I don't know. Police: Dispatch said you had everything on camera, can you review video to check? You: No. Police: Why not? You: I didn't listen to that one guy's review on Amazon and bought Zosi's B&W CCTV Cameras in 2021.That's not to say that these wouldn't be fantastic for some things. I could see these cameras being extremely useful for remaking your own version of Perry Mason or Dragnet. They might make some good footage for your home edited episode of Car 54, Where Are You?. If that's your thing then by all means feel free to ignore my review and be as creative as you can be.If you'd like a Security Camera that will provide some semblance of evidence in the event of something unfavorable happening in their presence, I'd look elsewhere. I most certainly will be.

I ordered these to replace some existing analog cameras mon my stand alone security system. I do not have a DVR , I connect these existing cameras via a 8 port switch that sends the camera selected signal directly to the RCA AV port on my TV via the BNC terminated cables that came with the existing cables. When I connect any one of the four cameras in place of my existing cameras I get a "no signal" on my TV. I can reconnect the old cameras and they work ok. Do these cameras HAVE to be connected to a DVR in order to work? The instruction book that came with the cameras states if the BNC cable will not connect directly to your tv RCA AV port, then you will have to use an adapter on the cable. That makes me think they should work direct connect to my tv and not need a DVR.I am using the supplied power adapter and four-way splitter for power for the new cameras. I am using the cables supplied with the new cameras also. Checked all four cameras and cables and the new cables will not make my old cameras work either. The power supply shows 12.7 volts on my Fluke DVM.

I bought these cameras to go with my existing Winbook security DVR. The DVR does not recognize the cameras. I hooked up one of the new cameras directly to my TV and it is scrambled and the TV tells me it is PAL format. The stickers on the bottom say NTSC. I switch my input mode of my DVR to PAL to test the new cameras are still not recognized.I sent ZOSI an email a week ago and I get no response. I will give this review a couple days and then I will send back the cameras for a refund before it is too late.👎👎👎👎👎

I have over 2 dozen of these cameras, I'm mostly happy with them. Picture quality is amazing and night vision is crazy good kinda like a spot light is on. Several times I thought I left my patio light on and after going out there it was pitch dark. A few of the cameras got condensation inside and one quit working but that's only a few of them, most pumping out quality video and incredibly inexpensive.

I installed these cameras for the office and they were easy to install and work great. The dome camera is much easier to get that perfect angle whether you’re mounting on the ceiling or on the horizontal wall. The body of the camera does feel a little cheap because it is plastic but they are very light. I mounted the majority of them on the fiber board used in the ceiling on a drop ceiling so being light is great. Obviously you will need a DVR so don’t forget that. Night vision is great as long as there’s no car lights shining through the windows. Thankful I have never needed to use them but they are extra security just in case.
