ZOSI 1/3" 4.6mm 700TVL Superior Resolution Home Security Camera System Color CMOS Weatherproof Video Surveillance Camera, Long Distance Night Vision, Mini,Vandal and Water-Proof Body

Good quality for the price. Works.

I bought the ZOSI 4PACK 1920TVL 1080P 4-in-1 HD TVI/CVI/AHD/CVBS Security Cameras 100ft Night Vision CCTV Cameras Home Security Day/Night Waterproof Camera for 960H/ 720P / 1080N / 1080P Analog DVR Systems cameras to start replacing a 10 year old camera system already in place that was starting to become more of a nuisance than a surveillance system. The old cameras became so bad that someone walking directly in front of the cameras couldn’t be identified 10 feet away. Because I work in a prison, I have higher security surveillance in some areas and less critical lower security surveillance in others. I chose 3 different camera styles with different viewing capabilities for the areas I was trying to surveil. One of the requirements I had to have was total compatibility with my current system and there was no problem with any of the cameras that I hooked up- basically plug and play. After reviewing footage of these cameras, I was extremely impressed with the clarity of the video and in the application I needed these cameras for, I had to have a wide angle view to cover a lot of ground. I then installed 2 (for a total of 8 cameras) ZOSI 4 Pack 2.0 Megapixel HD 1080P 4 in 1 TVI/CVI/AHD/CVBS Security Cameras Day Night Waterproof Camera 100ft IR Distance For HD-TVI, AHD, CVI, and CVBS/960H analog DVR System cameras for roof placement and my larger areas like the gymnasium. While I was installing one of the cameras, as soon as it was turned on, it fogged up and gave me a “No Signal” error. I replaced it with a spare that I had and had no further problems. Image quality was phenomenal and I had better coverage than my previous setup. The last 4 cameras I bought were ZOSI 2.0 Megapixel HD 1080P 4 in 1 TVI/CVI/AHD/CVBS Security Cameras Day Night Waterproof Camera 65ft IR Distance, Compatible for HD-TVI, AHD, CVI, and CVBS/960H analog DVR ones that replaced some of my internal cameras around our Culinary department and visiting areas. And again, I had no complaints with the quality of the images. After about a month of continuous use, one of my first 4 cameras displayed images that began to turn green, then purple, and then faded to black. I had lost the image completely. As I only had access to email since I work graveyards and most people are comfortably asleep in their beds, I contacted Zosi Customer Service and explained the circumstances of my failed cameras. Within a day, Coco had contacted me for more details of the malfunctions. After I sent model and serial numbers for the defective cameras, she sent me two replacement cameras without waiting for the faulty ones to be sent in. For me, that was a first! The usual process has always been- File a claim, wait for a return label, wait for the company to receive the product, then wait some more for them to tell me it was something I did, then argue back and forth until they reluctantly send me a replacement. In this case- not a single complaint about how the claim was handled and Coco was absolutely great! She was able to get back with me within a day or two at most and had all my questions answered and new cameras sent to me- all right before Christmas! Thanks for such an awesome experience!!!

Arrived on time, worked as advertised, replacing another bnc camera, basically plug and play

Great quality especially for the price, added another to my cctv system, tried many brands but zosi is definitely the best 👌

Have been getting many ZOSI cameras this year, at least a dozen, 4-5 different models. Found couple defective ones that the company replaced without too much hassle. This one is almost entirely plastic and weighs less than half as much as others before. Seems to work better than the others, about 80deg wide angle, good night vision options. ***Huge caution against using the "Reset" option in the menu. I tried it on this one and thought that killed it, but it came back on after a couple minutes, not 5 sec. as noted in the instructions. I have another (similar) ZOSI model that I "reset" but it is a gonner (will show scrambled video sometimes, mostly black screen). I will try and return/exchange that. No more resetting for me! Overall video quality is good (not bad, not great). It does not do well with sun lit and dark shadow areas in the same view. Lots of controls in the menu to try, but I could not get a good balance when sun and shadows are in the view. Does very well if the view is uniformally lit with normal daylight. Night view is good but if your view is less than 15 feet, the IR projects a bright spot at the center rather than an uniform flood lighting. If your night view is more than 20 feet, the IR brightness drops off quickly. I found it best to try the default setting first, then change only what you don't like a little at a time. Changing a setting during the daytime can also change the night setting at the same time (for better or worse).
