This blog explains why PTZ cameras are more sensitive to horizontal movement. It covers key reasons: mechanical design (pan is more efficient than tilt), sensor/lens optimization for horizontal coverage, stable weight distribution for panning, real-world surveillance prioritizing horizontal motion, and zoom amplifying horizontal sensitivity. It notes this is a deliberate design, not a flaw, to boost PTZ’s core tracking function.

from 5965 reviewsHad a client order. This my be my new goto. Only consideration is it's very big. Plan your mounting space according and some of the included mounting hardware was not very helpful to a typical senerio.

Excellent value for money, it was easy to mount, night vision is ok as long as you don’t have too much light in the background, sound is very clear

Easy to install, great sound and picture quality, and a great price

I bought two of these cameras and I’m really impressed with how versatile they are. One is set up in the living room, paired with my Jennov Doorbell, and it acts as a chime. This is honestly my favorite feature, it works perfectly and makes sure I never miss someone at the door. It also doubles as a security camera when I’m not home, so it pulls double duty without taking up much space.The second one I installed in the garage for general surveillance. I often work on my bike out there, and sometimes I don’t hear the doorbell when deliveries arrive or friends stop by. Now the garage camera chimes when someone presses the doorbell, which is incredibly convenient. I love that both cameras serve as reliable chimes and functional security cameras.As a camera, the Jennov A31 performs really well for the price. The picture is clear, the field of view is wide, and the compact design makes it barely noticeable. Overall, I’m really happy with these and would definitely recommend them if you’re already in the Jennov ecosystem or looking for affordable indoor cameras with bonus features.

Easy to install, functions exactly as it should perfect to see my dog during the day

This camera is so easy to set up and use with a very clear picture. It alerts me on my phone every time my dog walks past it so it’s very efficient. Great price too.

This camera/motion detectors awesome! Picture is pretty good. I set up the motion detector and alarm. When I get home I go in the app and set it to "home mode" to disarm alarm and constant motion detection alarms so they don't drive me crazy. When I leave the house I go in app and put it in the "away from home" mode. That turns on alarms and motion detectors so I get notifications if someone tiggers them coming into home. When i watch live videos on the app I can hear very clearly people talking. I can push speaker botton to talk to whoever is in my home. The app is easy to use. I did have some trouble getting one of the cameras to connect. But after a few tries it did. I do have wifi issues so could have been the issue. Anyways the alarm is pretty loud. I open my front door to test it and the camera pointed at it was triggered. My only grip is the alarm only goes of for 30 seconds. It goes on and off in 30 second cycles. A continuous alarm would be better. But it's not a real security system so good for what it is. The alerts on my phone are loud so if someone breaks in I'll be alerted immediately and can call police. I highly recommend.

Works perfect - decided to purchase 4 more to add to existing set of 4 - now I can see and monitor my parents house in case something happens when I am not home with them.

A while back I bought a door camera from A31 (D130). Great camera and great app, for viewing.I had an older indoor camera (different vendor), but the app became over run with ads and ultimately unusable, so I bought a A31 C100.The new A31 (C100) is a better camera and uses the same app as the door camera. Win..Win...Life is now much better!

I purchased this solely because I had an inoperative hardwired doorbell and didn't want to fix it. It works great as a chime to our Jennov doorbell, and doubles as a camera to watch our rear door! Very pleased! Install was super easy and seamless. NOTE: If you have mulitple zones, like we have an "indoor" and "outdoor" zone, the mini and doorbell must be on the same zone. If not, you won't be able to get the doorbell chimes inside your home.

Love this camera! I’m using it as a puppy camera to check on my puppy while at work. Audio picks up on everything including the white noise from the AC. Night vision is good! My friend has the original and the video quality for normal and night vision is better; I would recommend this one to the original if you have a smaller dog. It notifies me if it disconnects; when I check the app it’s typically back up and running. I haven’t needed to pay for the payment plan yet but will update later if I end up getting it.

They work amazingly well i liked them so much i bought multiple for indoor and outdoor use. They are easy to set up and the light is pretty bright. Great value for what they do.

10/10 recommend!!! Worth EVERY single penny! I bought this for my living room/dining area. The set up was very simple & I’ve had this hooked up for about 6 months with no issues!

Easy setup. Works and looks great! Very happy with it!

Easy to set up, great video and camera quality, has night vision, sound quality good for listening and talking, sleek design. I feel safe and I can check on everything on my phone through app. Overall great purchase !

This blog emphasizes that network cables are the lifeline of PoE security systems. It explains PoE cables’ dual role (power + data), how bad cables cause issues (power loss, blurry footage, overheating), key features of quality cables (category, copper conductors, certification, weather resistance), and why a 1-meter short cable aids troubleshooting—helping users maintain reliable PoE camera performance.
This 4K security camera guide explores the power of high-resolution surveillance. It explains 4K’s key benefits—crystal-clear details (e.g., license plates, faces), wider coverage per camera, and better post-recording zoom. It also covers considerations like storage needs, bandwidth requirements, and compatibility with systems, helping readers choose and use 4K cameras effectively for home or business security.
This blog outlines the top 5 advantages of dome security cameras. It highlights their discreet design that blends with surroundings, tamper-resistant structure (hard to reposition/tamper with), wide viewing angles for broad coverage, weather resistance for outdoor use, and versatile installation (ceilings/walls). These perks make them ideal for homes, offices, and retail spaces needing reliable surveillance.
This blog answers whether the "Z" (Zoom) in PTZ cameras always means optical zoom. It explains that while optical zoom (using lens adjustments for sharp, lossless detail) is common for "Z", some PTZ models use digital zoom (enlarging pixels, causing quality loss) instead. It breaks down the differences between the two zooms, why manufacturers might use digital zoom, and tips to check which type a PTZ camera has—helping buyers avoid misunderstandings.
This blog focuses on window security cameras, explaining why they matter (windows are security weak spots) and key features to look for: glare/relection reduction, suitable night vision, weather resistance (for outdoor use), compact design, and custom motion detection. It also guides on installation—prioritizing high-risk windows, choosing indoor/outdoor mounting, and avoiding placement mistakes, plus bonus usage tips.
