.srt is supposed to be a captions file. Just standard text. As tomcctv stated, often used in point of sale systems (overlay transaction data of the cash register on the video feed). Try opening with notepad in windows and see if it opens as a text or gibberish. If it opens as gibberish then the system has used .srt file extension with some other file format.

Yes, same company and usually same products under another brand (Lorex) without the 'premium' features of Dahua analytics. Dahua IMOU range is a separate production line (probably similar internal components). Agree to the point about full support.

Lorex, Amcrest and a few other rebrands of Dahua will be of standard Dahua quality for their low-end line. Dahua original cameras tend to have all their analytics/Artificial Intelligence functions. Those sort of functions is commonly IVS rules. IVS is the camera trying to work out the difference between a human/vehicle and then triggers an event when they cross an imaginary line. Far better than standard motion detection which triggers on a bug attracted to the camera. Example image is from Dahua with a tripwire IVS rule. Car crosses the line and it does something (notifications, records, sounds an alarm). Dahua does have system that use Coax, however it is best to use Ethernet cable (Cat5, Cat6). Can you use the coax cable to pull an ethernet cable through your roof space?

That web GUI looks like XMeye cameras. System > 'Net service' has the menus for Cloud and DDNS. However.... cloud stuff on these is P2P with XMeye's servers. Anything of P2P is not that secure. DDNS is for port forwarding a device and having another DDNS service keep track of the IP address your router changes to. Otherwise you can pay your internet provider for a static IP address. But this is also not secure.

hang on, sneaky link to your website (based on the site domain and your Cctvforum username) and YOU SAY 480TVL IS STUNNING IN 2022????

True to that. Plug a standard router into the camera and use a power bank, then connect your phone to the WiFi from the router. It will be as if the camera is connected 'normally' to a network.

Theoretically an Ethernet to USB adaptor should work. Configuring the network adaptor on a computer and plugging an IP camera in works. I don't know what it would involve to host a network adaptor and change it's settings. I do guess that the phone will require 'USB on the go' support.

Turn off the DVR (unplug from power) Open up the DVR. Find a small coin battery. Take out the battery for 30 seconds. Place the battery back in. Power up and see if system settings have disappeared. The battery is used for the clock time keeping but some use it to power the chips storing system data.

HDMI over Ethernet with USB passthrough (mouse). or HDMI over IP with USB passthrough (mouse). HDMI over IP devices will allow for multiple receivers of the HDMI signal however I don't think they offer one with USB passthrough.

I know both Hikvision and Dahua have all these AI capabilities in their high end models, People/vehicles in wrong areas is easy with standard line crossing or in area detection. The $150 - 300 price mark cameras. Standing too close to machines is a difficult one... the camera would use the same as above (line cross or in a box) but I would be weary of false alarms. I'd have to see a picture of the area first. Might be advisable for an IR beam detector and that connected to the camera. Wearing PPE is limited to the high end stuff that Dahua/Hik makes. I have seen a Dahua demonstration but not a Hikvision one. The companies are competitors to each other so I presume Hikvision has similar to Dahua. Given that Dahua has it, I presume non-Chinese companies like Axis and Avigilon will have similar (at least soon). There is a Ban in the United states on Dahua/Hikvision for government use and I think it expands to installation by installers. For now end users can use it.

Unplug the power from the DVR. Open the DVR. Find the small button on the circuit board. Hold down the button. While holding down the button, power the DVR. Be careful not to touch anything else as this is now powered. After 20s the DVR should start a factory reset. This erases everything.

Easiest way I would do is use a modulator with a "loop through". Another option someone suggested to me was using a 1 to 2 splitter in reverse, so it combined the modulator with the Antenna/amplifier/street input and outputted to the splitters doing each TV. That was suggested by a TV installer to me at the time I was looking, I have never tried it though. My own home uses an amplifier with an extra input labelled as "back feed".

Hello all, I'm Mark. CCTV has been a great use to me, it's always interesting to see what just happened. I am an end user gathering equipment and playing around with it. So far I have Dahua, Axis, Bosch and a crappy Swann system I got given. By far, in my option Axis has the best over all image and user interface. However Dahua has great image for 1/3rd of the price. Here, ipcamtalk and a few other forums I am on.
