What to do when CCTV cameras power supply stop working?

Your CCTV camera isn't working? No image or video? The problem could be your power supply. CCTV power supply is a necessary part of the CCTV systems-if it fails, your camera won't work as it should. Some of the common issues of CCTV cameras include:

  • Not recording any video.
  • The night vision is not working.
  • The CCTV camera playback is not working.
  • Not being able to view CCTV cameras remotely.
  • CCTV is not recording 24/7.
  • Not showing video, but the LED camera is on.
  • CCTV camera not connecting to WIFI.
  • The video is blurred or has no color.
  • Red and green lights continuously flash on the NVR or DVR.

Ways you can solve your CCTV camera issues

1. Check the CCTV camera connection and power

When your CCTV camera is not working, you should first check if all the connections are correct and the camera is powered up. Refer to the user manual with the camera to ascertain if you've connected the camera correctly. If your CCTV camera is wireless, you'll need to check with the wifi connections-you can test if the connection is okay with a network cable. Confirm if your router is functioning properly.

If using a wired CCTV camera, check whether the power supply and video signal are well transmitted. For PoE cameras, make sure there is a proper and functioning PoE injector or switch. For NVR cameras, check all the system connections. 
Check the settings of the security camera

You may find that your camera is not working 24/7, not connecting to the wifi, or not recording at night-these are problems you can solve by checking the settings and setting them up. Some of the CCTV camera's features are enabled by default, while others require manual enabling.

2. Check if the cabling is correct

If your LEDs lights are not on at night, it might be a cable issue-this can result in no video or image recording at night. You can get another cable and connect to the camera to check whether the problem is still there.

3. Reboot the CCTV camera

The golden rule to troubleshooting in IT is to Reboot the device. You can reboot your CCTV camera to get rid of the cache, settings to reset, and connections to self revise. To reboot, plug off the power supply, hold on for a few minutes, and plug in again.

4. Update your camera to the latest firmware and software

One of the major reasons your camera is not connecting to the software is that the software's compatibility and firmware are not up to date. Most of the providers provide consistent updates to increase the camera capability. 
Once the firmware is updated, check that the software is updated too.  Check on your provider's website often, in case you don't receive the notifications updates. 

5. Check if there are IP address conflicts

Each camera should have a unique IP address to receive and send data through the internet or PC network. If another device uses the same IP, it will create a conflict, resulting in the CCTV camera not working. 

6. Ask for help from the tech support

After trying all the above measures and your CCTV is still not working, it's time to call for help. Most companies provide free technical support, and you can call or email them. A technician from them will be able to provide a solution to your issue. Give a direct explanation of the issue so that they can give an accurate solution.

Types of CCTV cameras

There are varieties of CCTV cameras to select from. The most known ones are:

What is the difference between an NVR and a DVR?

NVR (Network Video Recorder) -It's a recorder that records videos directly from the network with the aid of Cat5 or Cat6 ethernet cables with RJ45plugs. NVR system is used with IP (Internet Protocol) cameras. There are two types of NVR: PoE NVRs, which have ethernet ports for connecting to the PoE cameras. The second one is Wifi NVR; this one doesn't have camera ports; they connect to wifi cameras wirelessly.

DVR(Digital Video Recorder) -This recorder processes uncompressed videos via coaxial cables, compresses them to a digital signal and sends them out. The DVR system works with analog cameras.

Differences between NVR and DVR

They are used in IP cameras They are used in Analog cameras
They use ethernet wires or cables They use coaxial cables
They are expensive but still affordable  They are cheaper
They have high resolution and high FPS  They have low resolution and FPS
They support cloud-based servers  They support local hard disk storage only
They use the latest, more advanced technology They use traditional CCTV systems
RJ45 ports for IP cameras  Coaxial ports for analog cameras
They process video data at the camera They process video data at the recorder

Advantages of NVR CCTV systems

  • They record higher quality videos: NVRs are paired up with IP cameras, possessing a resolution of 2MP-12MP(or higher) which DVR systems don't have.
  • They are easy to wire: it's a headache to set up CCTV cameras for cabling, but the NVR system makes it easy even for beginners. The NVR wifi gets to the network wirelessly; hence no worry about running wires to the NVR.
  • The recorder is flexible in replacement: as NVR uses IP network cameras, you can place it virtually anywhere, like at the garage, backyard, front door, etc., as long as you have a network.
  • They are easy to configure and easy to use: you may think NVR involves many network configurations, but that's not it. With P2P NVR cameras, you can set up the system with zero configurations. You'll download the NVR software, and the IP cameras will pop up in the LAN network device list. Read more on LAN here
