Cctv camera

[dr. d]

baket naman ganito na kapiraso bakal ay pag kamahal, 200 to 400 kesos kada piraso

400 bucks each!
i am confident, there are significantly cheaper alternatives.
one has to but look around.

you might even make pa-sadya. i imagine, it'd still be much cheaper.

I am planning to add at 2-3 more IP cams to my current one. I'm thinking of buying a 4-way power supply splitter to power up the others. If my current tp link IP cam is 9 volts 0.6 amps, then I would need at least a 9 volts 2.4 amps for all 4? There are 2 other variants I saw available, a 2 amp and a 3 amp. If I switch to a 3 amp, won't it overload 1 cam or say 2 cams only if I plan to add cams 1 unit at a time over several weeks or months or even limit it to 3 only. Also, will a 25 meter length work? I think this is the set up for 4-8 cam CCTVs which have wires as long as 20 meters? Thanks.

A 9V with 3A (or higher A) power supply is fine as long it's of relatively good quality. Some crappy PSUs will say it's rated for 3A but folds at 1.5 - 2.0 A.

The cameras require 9V but will only pull the current (Amps) it needs.

the length of wire is a factor that will add resistance to the circuit and could cause a voltage drop from 9V and affect the camera operation. with longer wires between the power source and the camera, you may need a higher voltage than 9V

as for the current, since your circuits require a total of 2.4A you will need to use a 3A maximum limit to ensure that your power supply can provide the current needed by each camera to operate properly.

if the cameras are POE compatible you can supply the power through the network cables

Thanks for the tip on buying higher amp Sir OJ88, so there's no harm using a higher amp supply than the requirement of the cam.

Sir Kisshmet, is it safe to go up to 12 volts? There's no info regarding cam power requirements except the specs on the supplied adapter which is 9 volts. My unit is Tapo C320WS and I plan to add the same. Thanks.

Don't use 12V. The current draw is low enough so voltage drop below a dozen meters or so can be ignored.... unless you're using very thin wires.

These should work quite well.

its hard to say for sure 12V is enough

the longer the wire the higher the resistance will be generated in between the power supply and the camera

also, the bigger the size (AWG number..the lower the number the thicker is the wire) the lower the resistance will be

so it depends on the length and the size of the wire that is used, what the voltage drop will be

non technical people can do a trial and error..electronic engineers can compute it

if tplink support wont tell you what the maximum voltage the camera will tolerate, then stick with 9V. if the length of wire you will use in a particular camera will cause it not to operate then the voltage drop is significant. in such cases use a thicker wire to reduce the voltage drop

Thanks again OJ88 and Kisshmet, I guess I'll try to ask the advice of the seller which Oj88 recommended at Shopee.
