Hikvision DS-2CD2783G1-IZSB Camera 7Buying Guide For CCTV Cameras

Resolution  Resolution is the most important and primary factor to check before buying a CCTV camera. The better the resolution, the better is the picture quality. When the resolution is poor, then you see barrel distorted images or videos on the screen and they pixelate.

When you see footage and images are not clear, then you fail to recognize the faces, which is an example of poor resolution. Nowadays HD cameras and IP cameras are in more demand and they are available with very good resolution quality. Buyers like 1080P resolution quality very much.

Night-Vision  Night vision is a must for any CCTV camera. If you have installed a CCTV camera, then it is for 24*7 support. When night vision is not clear then you may miss some very important clippings and activities that may cost you, dear, security-wise. Most of the cameras are with IR support. These IRs turn on and off based on the natural light available.

Varifocal lens- A varifocal camera allows you to adjust between its top and bottom limits on its view angle. This means that you can manually set both the view angle and level of zoom. Have a scenario where you need to zoom in on a gate or other access point? Use the 12mm setting (12 degrees and about 4x zoom). Need a wide-angle view? Go with 2.8 mm (109 degrees). Need something in between? Try 6mm (~45 degrees) or 9mm (~30 degrees).

Hikvision DS-2CD2783G1-IZSB Camera 4Digital camera– An IP camera is a digital camera that functions on the laws of Internet Protocol (IP) networks instead of analog electric signals. IP cameras capture in megapixels which are better versions for higher picture quality. 

Power-over-Ethernet– In PoE technology, you don’t require a separate power cable and ethernet cable for each camera. It keeps the system smoother as there is a lesser number of wires. 

Passive Infrared Motion(PIR) Sensor– It is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. For that purpose, an imaging IR sensor is required. A PIR-based motion detector is used to sense the movement of people, animals, or other objects.

Two-Way Audio– Two-way audio makes you more powerful as you are in a position to pass instructions and guide or growl at a threat from a faraway place. It keeps you in the command.

Waterproofing– Check if the outdoor camera is compatible in stormy weather. IP66 layers are a must for cameras. It happens often that cameras develop glitches in strong weather conditions. Any good outdoor camera is weather resistant.

Wireless & WiFi– When cameras are wireless & wifi Accessible, then no clusters of wire around and it is always easy to access them online through any router installed in the range. It gives you the freedom to monitor from any remote location.

Recording– Check if cameras have a slot for an SD Card. Also find that you can preserve recording in the cloud or not.

Warranty– Warranty and company support are important. Cameras are always installed at key points. When they go out of order, then it is a threat to security. There comes the condition of warranty or company support as handy. A good company has always customer-friendly policies.

Users Review

Donn E Bly Shared their opinion:

  • As a wide-angle camera, it worked great out of the box with perfect focus, but I wanted a camera with zoom so that I could tell whether someone had left the deadbolt disengaged or not. This camera met those needs, and I can now tell via camera whether or not the door is locked. The ability to change modes via dip switch on the end of the power pigtail was nice as opposed to dipping switches on the camera body.
  • If you have never used a dome camera before it may seem awkward to mount, but if you remove the Allen hex-head set screw and unscrew the retaining rings everything comes apart and you can easily screw the base onto the wall or ceiling surface. In my case, I used standard #8 wood screws because I was going into the stud behind the drywall instead of using the supplied screws and anchors.

Brett says that

  • In the past, I’ve purchased fixed-lens systems (typically 3.6mm) and a pack of M12 lenses of various focal lengths. While this approach works in principle, in practice it sucks. Each time you want to change the focus, or focal length you have to disassemble said camera; that gives the chance of breaking something, introducing moisture, dirt, etc. Further, there is the issue of constant changes in temperature, weather, etc which can cause CCTV camera lenses to go out of focus
